Testing the coil pack

[1stGenSHO]

Hello Everyone,

Does anyone know if there is a procedure to test the coil pack using an ohm-meter?
Chiltons seems to skip it for the SHO.

Thanks,

finger test it, stick your finger in the terminal on the coil pack and crank the engine. if you get shocked, then that one is obviously firing.

Ha Ha. I'll crank the engine, you check for spark!

You should be able to tell if the coil is open with an ohm meter. Test between the coil input terminal and the plug wire terminal. You can also compare the readings between coils to see if one of the three coils is out of line.

Remember that there are only three coils in that pack. Terminals 1-5, 2-3, and 3-4 are paired on their respective coils.

To check the primary side of each coil, check for resistance between the input terminals C1, C2, and C3 to the COIL POWER terminal. Each should have the same resistance value measured.

For the secondary circuit of each coil, measure each output terminal pair to the case ground and to the COIL power terminal. Check for the same reading on all three terminals.

Check for shorts between the primary and secondary circuits. This will find a gross short, but will not locate leakage current.

Sorry, didn't find actual reistance values to be expected and since it's only 36 outside, I ain't going out to test mine.
