What should the voltage be on a HEI distributor?
Disconnect the green and white wires from the module and touch the positive meter lead to the green wire and the negative lead to the white wire. The normal reading should be between 800 – 910 ohms. Testing the primary circuit of the coil. The remaining electronic part that would keep the distributor from firing is the module.
What kind of voltage does a performance distributor need?
If the connections are good, you next need to make sure the unit is getting a strong 12 volts. Many times, a low-voltage issue can cause a myriad of problems. The wire carrying the 12 volts should be a minimum of 12 gauge, and have no resistors in line.
Can a jumper wire be attached to a performance distributor?
But, if the ground from the engine to the battery is making a good connection, ignition spark will be none existent. To test for a good ground, a jumper wire can be attached to the distributor by connecting it anywhere on the housing and running it to the negative side of the battery.
What do I need to troubleshoot a performance distributor?
To do this, you will need a 1/4-inch nut driver and a multi-meter. To test the resistance of the coil, remove the coil cover so you can see the red and yellow wire. Using the multi-meter set on the ohms setting, touch the positive lead to the red wire terminal and the negative lead to the yellow wire terminal.

What should the voltage be on an ignition module?
Voltage, measured at the coil’s + terminal, must never exceed 13.7 volts at any RPM level. Too much voltage going to the coil’s + terminal can cause the ignition module to overheat and run erratically or fail.
