how much voltage do you have going to the coil primary circuits, perhaps your alternator regulator is stuck and the alternator is putting out the maximum voltage that it can, perhaps like 17 volts and the coils cannot handle that for very long.
If you give me the engine that came in it, I'll look up the wiring diagrams.
Ok, but still how much voltage do you have going to the coil primary circuits?
You should check the grounds also, you can use a voltmeter to check the voltage drop across the ground circuits. Hook the positive end of the voltmeter to the negative ground wire of the coil you are testing as close to the coil as possible, the attach negative voltmeter test lead to the negative battery post, then turn the key to run and note the voltage. It should not be more than 0.2 volts. If you have more coils, test them all in the same manner.
Do you happen to have an aftermarket alarm system installed?
Did that answer your question? If so, kindly leave me a positive rating, so I get credit.
