Testing Gm Hei Ignition Coil at Gabriel Chubb blog

Testing Gm Hei Ignition Coil. The easiest way to test a module on the car is to ensure that the wiring & pickup coil are ok. Is there a way to test the coil and module to see which one needs replaced? I put one of those cross. From what i've read, the hei coil should test within the following parameters: I've got 12v at the + terminal during. If all of that checks out, the following steps will help you to test the coil inside the cap, and the magnetic pick up. To test the pickup coil, unhook the two terminals carefully, test each one to see that they're not grounded by hooking one tester lead. I recently bought a used but supposedly never installed mallory 8555401c gm style hei distributor for my 351w. If you have a separate ignition coil (inline six or four cylinder) remove the cap and rotor, but install the spark tester in the coil in place of the coil. To test the resistance of the coil, remove the coil cover so you can see the red and yellow wire. After verifying you have 12 vdc feeding your distributor of your hei distributor remove the coil. The module is essentially an amplifier.
