Same large cap HEI, for use with MSD ignition box and coil, and to remove the stock HEI module, use MSD 8400, uses 6A box, remote coil (no rev limiter), or the 8500, uses 6AL box, remote coil (with rev limiter in-box). The 3rd was an Accel coil. Discussion in 'Engine/Drivetrain' started by jaybird, Sep 6, Coil from a 1972 Chevrolet k10 4wd truck with a 350 CI engine Autozone P/N C819 the magnetic pickup will signal the ignition module through the wires attached to terminals W & G to create a ground on post C, which then grounds the coil and makes HEI Kit Installation Instructions For Summit part numbers: SUM-850030, SUM-850031, SUM-850032 Parts Included: 1 – HEI distributor cap with brass terminals 1 – HEI coil w/ silicone washer and carbon contact brush (all installed in cap) 1 – HEI coil dust cover (installed on cap) 1 – HEI distributor rotor 1 – HEI wire retainer I have had a bad ignitor allready and swaped it for an old one but last week either the ignitor or the pickup coil were messing up but now it is running good again and it all test OK. GM made a year divider on the pickups, and from a certain year Down were one Went out and bought new ignition module for hei distributor(no luck)then bought the part that plugs into the distributor cap has 3 wires, don't know what its called (no luck) then bought coil (no luck) still no spark. Recommend To Use With High Energy Ignition (HEI) Module Part Number: 83647. Remove distributor cap and rotor, and disconnect pickup coil leads from module. wires from magnetic trigger to Sniper. gm hei pickup coil. Connect the multimeter’s BLACK test lead to one of the connector’s female terminals (using an appropriate test lead). Install the s upplied harness, PN 5 4701, to the Timing Control then locate the ignition coil. MasterPro Ignition Coil On Plug (COP) - 2-50152. Can damage standard coils with it. The resistance ranges given are correct. 00 check the pick up coil wires to make sure they are not broken ( common with Gm hei's ) check the pickup/pole peice magnet assy for cracks ( they do ocassionally crack and if it cracks or is broken it will screw up when the heat expands it ) then go to the module , for this find a module you know thats good . Splice the RED wire of the harness into the PINK wire coming from the BLACK connector of the coil (Figure 10). the HEI will just fail to work, Too high, coils will overheat and fail. 055″. SKP SKDIGM21. Testing a GM HEI Distributor, checking primary and secondary coil windings, pick up coil and bench top testing. Test W & G on pickup coil= . Either way, you can use a dirt cheap GM HEI module as a replacement ignition source to get your bike running again, with timing advance and everything! Coupled with the GM coil mod, you could completely replace I have around 10,000 miles on this motor and I put a brand new HEI GM distributor in, when we got the engine. Disconnect the pigtail at the module and measure the resistance of the pick up coil. E. However, the pickup coil (timer core in GM speak) produces an analog (AC) signal, so polarity isn't necessarily an issue, particularly since the original poster suggested that he was using the HEI module to rig a non-GM car. Replaced it with a parts store Reattach the wires to the positive and negative side terminals followed by the retaining nuts for both sides. The other components of the distributor, such as the mechanical and vacuum advance, gear drive and The high voltage pickup was a capacitive clamp that clipped unto the coils high voltage lead, but developed huge problems for them back in 72 when the HEI first came out. To test reluctor pickup with a Digital Multimeter, set to LOW Ohms, measure across If that won't bring it to life, check the Magnetic pickup, by measuring the resistance across it. The only variations I'm aware of for V-8 engines/HEI distributors--beyond GM having multiple part numbers to fit various distributor housings--is the magnetic polarity and wire length, as described above, and in my photo posted prevously by Kenth; and some pickup coils are color-coded via molded plastic connectors, others by colored tyraps on Find GMC 5. initial, 38 total. If that won't bring it to life, check the Magnetic pickup, by measuring the resistance across it. , Edelbrock performer 2. Running 12 volts to the bat connection on a HEI system is OK, my car I removed all computer related stuff through it into the dumpster stuffed a 383 into it with a HEI dist. I have not personally had that problem, and GM uses HEI on many of the high performance crate engines. DVOM (meter) still connected to green & white leads. (Note that external ignition coils are not color coded to the pickup coil. High energy ignition, also known as H. Have been reading the other questions and answers in here and a couple of the answers mentioned testing the pickup coil and distributor pickup coil. 5 Ohms Black Flame Thrower Coil. that way you know you have a compatible set. DIS ignition systems are much better in terms of reliability with less moving parts to fail however To test reluctor pickup with a Digital Multimeter, set to LOW Ohms, measure across the two leads that are connected to the GM HEI Module BUT disconnect them first. Connect ohmmeter as shown in step 1, Fig. Related Models. For that matter, the original HEI had the pickup, module, and ignition coil in close proximity to each other. Attachment Method: Bolt-On. also if it has a capacitor on it 2. Remove the distributor from the engine. the Distributor -REMOVE the -PIN in the DRIVE /GEAR & PULL the shaft up than A GM HEI module does not rely on slow thermal coefficients. FYI C4 Tech/Performance - HELP on HEI Coil, difference in R/W & R/Y wires, best one to buy - Hi, Help on the HEI Coils, what is the difference in the Red/White wire coil verses the Red/Yellow wire coil. Ensure you are getting the best performance out of your ignition system. 4. Dist cap has no apparent craks or carbon tracking. ignition pickup coil.
