anyone help me on a piece of elec problem?

Xact'ly What are you using for an igniton switch? Mopar switches have the resistor bypass for start built into the factory switch, whereas Ford, AMC and GM all use a second terminal on the starter solenoid.

So what are you using for an ignition switch?

More information is better. We could get out the "information crowbar." I used to use this a lot when I sold auto parts. "They're all the same."
