how does pertronix ignition work

. The distributor retains its vacuum advance and also its advance weights and springs, but the . The new module has 5 times the available energy as compared to a points system and has a built in Rev Limiter on the module. Use a fresh one as they slowly lose output over time. I just installed an Ignitor and Flamethrower in my 3.8L (4.3's cousin). The 12V source came from the driver's side of the car. I installed it and a Flamethrower coil in my 1970 351 Cleveland during a complete resto/rebuild. The performance of an Ignitor is dependent on all of the components in your Ignition system. UK/USA pre 1975/76 MGBs came stock with a 3 Ohm coi Connect the vacuum advance and bring the rpm up and you should see additional increase. Ideally the ballast resistance should match coil specs. For better performance, you must ensure that these components are in good condition, including the distributor cap, rotor button, spark plug leads, spark plugs, ground connections, injectors etc. Ignition Conversion Kit, Ignition Conversion Kit. are stock. Remove the resistor from the vehicle and splice the disconnected wires together at a single point. Using my "calibrated eyeball" it should be similar to the specs. Posted: Mon Jan 10, 2022 9:48 am Post subject: Re: 9N 12 volt pertronix electronic ignition. The Ignitor III you MUST run a full voltage to coil and you must use a coil at around 0.32-0.4 ohms. Do you mean a nominal 1.5 Ohm coil with a ballasted wiring loom, or a 3.0 Ohm coil (for any year wiring loom) with or without a ballast wire in the loom, or an external (e.g. The gap set using the 0.85mm plastic feeler gauge provided produces a dwell of about 54 degrees. Part Number: PNX-1265LSP6. Bypassing the ballast resistor is correct when using a 3 ohm coil, but when using a 1.5 ohm coil which is what mjeansonne is using, the resistor should remain in the circuit to prevent the coil from receiving to much voltage.. When the points are open, current is sent through the coil's primary windings, creating an electric field. Turning ignition on. Apr 15, 2016. We cover some tro. In cars with a push-button start, a small computer in the ignition switch sends a signal telling the battery to start releasing energy into the ignition system while activating the starter. The Pertronix Ignitor pickup component mounts in place of the points and condenser. Increase rpm to 2000 rpm and you should see the timing advance increase. 4. If you are getting less than 1/2 ohm you probably don't have a ballast resistor or resistor wire. You must use battery voltage, no ballast resistor or in the case of Ford, resistor wire. The distributor itself is a stock replacement with the points switched out for a Pertronix ignition module. Ignitor III Features: - Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance Pertronix now has their new Ignitor III module available for AMC/Delco Distributors. 1.5 or 3.0 Ohm primary resistance values available.. Hello all, A while back, my '84 Turbo Esprit came to a halt with what was diagnosed as a bad coil. ) As per the instructions , the red wire from the Pertronix is hooked to the positive side (+) of the coil which is also the post that 12 volts from the ignition switch goes to. it probably would work better on the 12V side rather than the resistor-dropped side. So it seems that the pertronix ignition is fried and I must purchase a new one. It provides increased voltage for improved performance and fuel efficiency. According to PerTronix, The Ignitor system has an effective rpm range from 0 to 6000 rpm with a standard coil. Some EFI systems just call this a points signal. Available chrome plated or black for that \"stock look\". I've been told this can't be done but it can. 1. (other than to drain your wallet) and, with the MSD, I don't see a real advantage to their separate CDI box (like the 6AL) over a new MSD Billet distributor with the built in module. The Pertronix will have no effect on the timing. The spark plug wires then carry the voltage to the spark plug where the current amps the gap, creating a spark inside the combustion chamber. For use with inductive ignition systems. If you need to go from 0 to 15000 rpm, all you need to do is change to a stock heavy duty coil. It's a points to electronic conversion unit that uses the OEM distributor by removing the points and installing the Pertronix trigger and control unit. As you can see it is not just as simply as adding the Ignitor and running 12-volts to any coil. BlueMule Gearhead . The system completely eliminates the contact points and fits neatly underneath the distributor cap for a "stock" look. There was a relay that clicked (activated) when ignition was activated. The red, depending on which set of instructions you got, should either go to the always-12V side of the ballast or the (+) side of the coil. The misfire persisted. Before that it was run to my MSD box. 2:1 improvement over "points" in current fall time for increased coil output. The car runs great and no more points maintenance will be needed. Pertronix Ignitor should last as long as any HEI distributor. The standard Hall Effect Ignitor module has the integrated circuit triggered by the cobalt magnets in the magnet sleeve or ring that is mounted on the shaft (usually on the cam lobes). Your 72/76 has a points/capacitor system. I have installed the Pertronix ignition and coil on my '55 C-3-B8. Compatible with all 12 volt negative ground systems.PerTronix Ignitor Systems can be used with any stock point-type coil, or . By the way, right now all of my ignition parts (coil, distributor, wires.) Before running it, I replaced the ignition resistor wire in the steering column to get 12 volts to the coil. Initially it was believed to be a fuel starvation/vaporization issue. I have never seen modified springs or curve in a stock 56 distributor. Seriously, its worth the time and money. At least you could plug it off if you don't want to use it. Aug 7, 2010. The car is a 1973 Buick Riviera with a 455 ci 8 cyl engine, air conditioning, power steering and brakes, and a turbo 400 automatic transmission. Never change points again with the PerTronix Ignitor points conversion kit.

Pertronix Troubleshoot Your Ignitor Episode 415 Autorestomod The Pertronix is one of the easiest upgrades to your car with points ignition. However, once the ignition key is turned on, a circuit is completed, allowing the battery's electricity to start flowing. Another thing I found out - make sure your generator puts out at least 5.5 volts cause the pertronix fails to fire below that. Posts: 1781 From: Kent Island, MD USA M&M # 2423 Registered . I'm upgrading the ignition points in my car to electronic. Another nice thing about this system is that you do not have to change the timing or your stock plug gap. When I disconnect the pertronix ignition from the coil, I have 12 V at the coil again. "To combat this, the PerTronix Ignitor system uses a Hall Effect sensor that replaces the troublesome factory breaking points. #1. The kludge circuit lets the ESA see 0V (real ground) when a Pertronix gadget really only gets to 0.7V (.7V above ground). While installing the pertronix (part number 1541 for the IAD-4008 in 12 volt), I found a broken advance spring laying in the distributor. #3. The electronic ignition system is the type of ignition system that uses electronic circuits, usually by transistors controlled by sensors to generate electric pulses which in turn generate the better spark that can even burn the lean mixture and provide better economy and lower emission. Turn the ignition switch to the run position. The Pertronix unit will usually work with this voltage, but there is a significant feel it in the seat of the pants improvement when you run the correct voltage. Cam and Jeff give tips and tricks on Pertronix 1 2 and 3. BUT you must use a Pertronix 40,000 volt coil that has a resistor built into it. We show how to install the Pertonix Ignitor I Pertonix Ignitor II and Pertronix Ignitor III.http://. True, the stock Ford coil works very well with PerTronix I. As recommended by others above, call them directly to 1) verify the correct trigger number for 6 volt, POSITIVE ground and 2) get the right coil for your system. Those still considered in danger of getting too warm were heat shielded. Now read the voltage at the positive coil terminal. High heat and/or high current will reduce the amount of time until it fails. I replaced the spring while I was in there. Or the coil will not keep up with the ignition system. The rub is after installing the Pertronix parts in the distributor, the tach now reads nearly double actual RPM. PerTronix Ignitor and Ignitor II will work with many aftermarket Electronic Fuel Injection(EFI) systems. Just be sure to remember to run 12 volts to the Pertronix unit. Either way there should be no reason for it not to work on practically any car, unless you have a glich such as bad ground , bad ignition coil , wiring incorrect , in other words something minor. I agreed to have this, along with the distributor bits, replaced by a Pertronix system (though, in the interests of originality, I might conside. I suspect the Pertronix circuit (it's two resistors and two diodes) would work with other electronic ignition setups. All fuel pipes were checked and re-routed where it was considered necessary. RWENUTS, Apr 7, 2013 SHARE POST #7 GMC BUBBA Member from Speedway, IN Like the others said, run the vacuum advance unit. Unfortunately, I'm 1500 miles away from the truck right now and do not remember which coil I got. The PerTronix Digital HP Ignition is considered a capacitive discharge ignition because it stores energy in a large capacitor inside the unit. 12 v ignition power source for pertronix. Connect PerTronix-I module BLACK wire to coil (-) terminal. M. The pertronix is a pickup and ignitor. The reason is that the coil was designed to operate at 9V. If you are not running an ignition box then just run the tach signal wire to the negative side of the coil. 1. It keeps peak energy throughout the entire RPM range, reducing misfires while improving performance. So usually the ballast resistor is no longer needed. Disconnecting the battery. I am a new Tiger owner and I inherited a Pertronix Ignitor system in my distributor. Estimated Ship Date: Sep 26, 2022 if ordered today. If you go with the pertronix ignitor, it replaces the points and capacitor. Use new wire with no resistance from ignition switch to PerTronix-I module RED wire. Best for improving performance: Pertronix D170600 Flame Ignition Coil. The Buick was running too close, so we had to take a little play out of the distributor. 10-01-2009, 06:16 AM. When you fit the Pertronix wire it exactly how the points where fitted, the only difference is the module requires a 12v power supply where the Points don't, Don't connect that red wire to the Coil + side as the instructions suggest as the Collapsing field of the coil means the Ignition module doesn't get a clean 12v feed. In a points system the distributor rotates and the points open and close. #1. Pertronix figured all this out years ago, and developed a kludge circuit to work around the problem. Nowadays coils are designed better and provide ample spark even during starting. Other type of coils will more then likely fail having 12 volts going to them. I generally suggest that a sreet car have at least 2 effective ground straps from the engine/tranny to body and a race car have 3 ground straps from the engine/tranny to body. any real advantage to an MSD system over a Pertronix style? How does a PerTronix ignitor work? Connect a test light to the switched wire running from the coil to the distributor (the one that is not the power wire) and ground the test light. Modifying the gap: Although you can vary the gap, it has limited range and effect. I'm sure the Mallory is no different. the MSD system costs $500 . I installed a pertronix ignition conversion kit in my CJ2A recently and all I can say is WOW!!!! A pertronix with vac advance is the same price as one without. Or you can mount a 1.5 ohm resistor on the firewall between the coil and ignition switch that will take the place of the pink resistor wire. Keep in mind that the Pertronix kit will not do anything to correct an old and worn mechanical advancing system. One direction is to connect it to the top of the coil. The original Prestolite coil is 1.5 ohms and original the resistance wire is usually around . With the PerTronix, it has an ignitor module that reads off of a magnetic sleeve that rotates and comes in the kit. Product Line: PerTronix Ignitor Lobe Sensor Solid-State Igntion Systems.

To start the installation of the Mustang Pertronix 71281 Ignitor III Electronic Ignition, or any work on my distributor, my habit is to check the timing and set it at number 1, top dead center.Make sure you are in neutral or park and that the parking brake is applied. A set of contact points inside the distributor are open and closed by lobes on distributor shaft as the engine spins. A pertronix works just like the newer stock electronic systems, but the igniter circuit is made so small that it can be mounted inside the dizzy with the pickup. However adjustment is far less picky than points so it's worthwhile to try for yourself. This Pertronix Ignitor System and Flame Thrower Ignition Coil Kit will take all of the guess work out of what is needed to improve the ignition on your Negative Ground MGB 63 to 74. Once installed, double check the BASE advance and the progressive and total advance against your OEM ignition advance curve graph. So, don't worry about frying the Pertronix. I'm not sure it has ever worked correctly. Plus you don't have the problem of points bounce / float or voltage loss at higher RPMs. PerTronix Ignitor Lobe Sensor Solid-State Igntion Systems 1265LSP6. Our baseline run gave us a peak power figure of 162.41 hp at 4,900 rpm and peak torque came in at 190.13 at 4,200 rpm. The MSD and Pertronix is a good combination and work well together. Possibly the electronic ignition module was also bad. Rotate distributor body anti-clockwise until light is out (equal to points closed). It is one of the relays under . For a PerTronix-I with Blaster 2 coil, correct connections are: Use original wiring with intact resistor wire (ballast) to coil (+) terminal as-stock. I also rebuilt the carb and replaced the plugs, cap, rotor and wires. The Pertronix wires, the black goes to the coil (-) terminal. Never change . As always, disconnect the battery before doing any work on the ignition system. primary ignition system or it will cause the system to shut down or overheat. Once we installed the gaggle of Pertronix gear and warmed the engine to the . This dual point Ignitor III from Pertronix will increase burn time, improve combustion, give you more horsepower and improve mileage. On to the ignition system. The distributor cap sends the current to the rotor, which in turn sends it back to the distributor cap sepal plug wire terminals for each cylinder in a timed manner. Attach positive (red) lead of your voltmeter to the positive side of the coil, and the negative (black) lead to an engine ground. Why Electronic Ignition System? The engine starts and runs fine. 62. I have my tach run to my Crane ignition box. I also installed a new ESA from CDI that accepts the Ignitor (suspected my old one was not working).<br /><br />I could not believe the difference in the idle performance. The sensor is essentially an electronic switch not limited by rpm or. Ron Tron wrote: (quoted from post at 13:35:31 01/10/22) I have seen to direction to the red wire on the module. Do NOT use a Flamethrower II coil with anything but PerTronix II, CDI, or MSD. This sets up a magnetic field in the coil's ferrous core. Rick E.
