Thanks for the reply and I wouldn't loose any sleep over it, A lot of us have PhD's by learning from our mistakes.
I still consider this Mopar site a virtual garage where we hang out, bullshit and bench race. I could care less who is butt hurt as long as it ain't me....and that goes for...
not just a constant....but minimum of a full 12 volts. The voltage will drop to below 12 volts on the "run" circuit when cranking. That is why you cannot just hook to it. And the cranking circuit is only hot when you are cranking the ignition. That is why they need tied together.
wired as their instructions said.
2 leads to the distributor (green / purple)
2 leads to the coil (orange / black)
1 smaller red trigger wire to constant 12 volts (minimum) **** here is your issue
1 large red to battery
1 black lead to ground
grey wire to tac (normally green wire from tac)...
I just put a 6al on my silver Duster and Butch's red Duster and have 2 tied to dual crank triggers on the Butch Leal / Direct Connection Hemi race car.
I love them. besides the 2-step rev limiter, you could weld with the spark.
and how is that working? the problem is as previously explained.
If you put a meter on the red trigger wire to the MSD box, I would bet that either a) it is only hot when cranking or b) it is NOT maintaining a minimum of 12 volts while cranking.
