Question about 1985 Jeep CJ7
So I have replaced the control module, starter solenoid, and coil and still no spark from the coil to the negative terminal for testing. I was told it should spark 6 times for every revolution and it will only spark once if at all. I checked the voltage and it was good (around 6v) when key is on but when cranking it is only around 8.8V and should be near 12V. I believe the resistance wire could be the problem. It says it should be 1.35 ohms and I found it around 1.8 ohms so it seems like it must be partly broken somewhere. Can I just jump 12V from the battery to the coil to check this or can it damage something?
Check to see if u have 12v at the pick up coil in the dist. if not thats ur prob. my 81 cj7 304 v8 did it

You can put 12 volts from the battery to the positive side of the coil with no problem.
