Re: 1973 cj5
He 'thinks' he has changed a stator too Bill....
My bet is still on the alternator excite dragging the coil power to ground.

Re: 1973 cj5
He's right about the voltmeter. His advice about tracking down the
spark is a good path to follow. The stock harness in a 73 has a resistor wire running from the ignition to the coil which drops the voltage (no ballast resistor). It should have around 8 volts at the coil. There is a plug in the harness at about the fire wall that is nortorious for corroding and breaking. I had a very similar issue (I have a 73 also). If it cranks over, getting gas, fire at the plugs, and the timing is close it should run. FYI...You don't have an ignition module in a 73. It's points and condenser.
