I have an odd problem

[Jeepcom23]

I havent been on in awhile. BUT my mj is done and running great with her new heart ( 97 ZJ Engine )

But Ive still got an odd problem.

My harmonic balancer arcs, in rhythm with the rpm, from the metal part of the balancer, across the little rubber piece to the other metal piece of the balancer.

 

Ive checked my grounds and what nots but I can't figure it out

 

Any ideas?

 

Thanks!

Arcs like sparking? Electrically, or like metal to metal contact casuing a spark from friction? Sounds weird!

as in electrical

Have you relocated the crank sensor from the flywheel to the harmonic balancer?

Never heard of that problem before. The closest electrical components to the balancer would be the alternator or ignition coil. If it's in rhythm with the RPMs, I'm thinking ignition coil. Perhaps the coil housing is cracked? Just a wild guess.

Nope.

A guy in my jeep club had the same problem. Remove your belt and see if it still happens. If the belt is slipping or worn out it will create static electricty by slipping on the pully and it will arc. Try it and let us know.

You have to get a video of this before you correct it. It sounds pretty weird.
