Hey, I am in aviation, if you think you made a mistake you go over everything again. No matter how crazy it sounds. It can be stressful.

Nice setup!

Mine is still sitting in a box. (Thanks Atomic!)
I havn't had time to install it yet. I'm on holidays this week, maybe...I can find time???

What is the part number of that coil? I bought the ss blaster and it looks like it doesn't fit and I'm gonna have to McGyver it in. Yours looks like it fits right in.

Mine (not installed yet...)

So I finally got motivated to install this stuff. I'm on holidays so I can take my time and make sure I do it right.

I hooked it up and...nothing... :(
No spark.

Didn't make any permanent changes.

No spark from coil.

I figure;
a) I have spliced into the wrong wires.
b) The 6a box doesn't work.
c) The coil doesn't work.


Anyone have any ideas?



EDIT: If I had to guess, I should remove the C black ground splice from the IGN Driver Harness going to the 6A.

The drop in bolt ons are 8231. Direct 50-sate replacement for $50.

Thanks! If this coil is defective, I've been sitting on it for so long that it's warranty may be up! I may have to buy that one!

did you actually crank the engine for the box to pick up on the spark trigger from the coil harness and fire the new coil of which it does not look like the ground of the tester is on the battery?
