Re: Brand new '89 YJ
No.
If the ballast 'wire' was bad, the engine would fire up and run as long as the starter is turning. The engine would then die as the key goes to run. He has the opposite happening. He gets one spark flash as the key goes to run which indicates a bad ballast bypass wire from the solenoid to the coil or an ignition module issue. He needs a multimeter or he will end up going nuts tossing parts at a non starter. Running a power line directly to the coil positive will sort that out fast.

Re: Brand new '89 YJ
I tried jumping directly to the coil, got nothing. I think I did it
right - it was hard to shove the cable in there, but anyway, this indicates a bad coil then?
