their is a spark jumping from the harmonic balancer to the fan every 2-3 seconds, I put a ground from the firewall to the intake, but still sparks?

Harmonic balancer coming apart?

flaglerXJ

No their is a 1.5-2 inch gap between the fan and balancer

It takes a LOT of voltage to jump a 1.5 inch gap. Your coil is not capable of doing that.

It's got to be static electricity. (That can generate far more voltage than your coil.)

I'd guess your harmonic balancer is rubbing on something.

I don't know it's crazy, will try to take a viedo of it wile it's dark

flaglerXJ

Here is a viedo, it's really bad but the gap is more like 1/2 inch. Not as big as I thought

If you stab the gas does the belt squeal? It's either a high voltage leak from the ignition or static discharge from the belt / balancer rubber insulator.

flaglerXJ

No it does not squeal, it will miss, stumble then rev up.

BlueRidgeMark

Wow! That's pretty cool.

I'm leaning toward a static buildup.

flaglerXJ

I added a ground as well as pulled my cool and wire brushed the bracket and the ground leads, got rained out, will give update tomarrow

That is the weirdest thing I have seen. It's definitely an electric type of spark, not a friction kind of spark. I really have no clue of what is causing that.

Static buildup on serpentine belt. Replace belt and use a Krikit tensioner to make sure it's properly tightened.

You could always get one of those chrome garden ***** for a hood ornament

Is this associated each time you see a spark?

flaglerXJ

No that what happens when I hit the Accelerator.
