Guest Posted November 7, 2001 Share Posted November 7, 2001 Hello, I have a simple question. On my 64 Wildcat 401cid, what should the primary voltage measure as I crank the starter? Link to comment Share on other sites More sharing options...
The Old Guy Posted November 7, 2001 Share Posted November 7, 2001 The primary voltage should be 12 volts or more ,depending on how hot your battery is. The voltage to the distributor should also be 12 or better during cranking ,and drop to 7-8 volts when running. Link to comment Share on other sites More sharing options...

Guest Posted November 8, 2001 Share Posted November 8, 2001 You won't get 12 volts while cranking. The key is to check the actual drop though the circuits. Check the drop between the battery negetive terminal and the starter frame, and then the drop between the battery positive terminal and the motor side of the starter solenoid while cranking. There should be less than one and a half volts drop on the negetive side and less than three volts drop on the positive side. Link to comment Share on other sites More sharing options...
