Did you pull the wiring from the coil and module, and run a hot wire to both, or in series, as shown in the illustration?
I made 4 test leads. One lead went from the + on coil to the + side of the battery. One was ground straight from that hei bracket/mounting nut to the neg side of the battery. Then two more leads from the hei to the pos and neg sides of the coil. It started up like this
Could be. I would check the air gap to be sure. Did you remove the distributor when you installed the system? Timing off? FWIW, I cut the plug out completely, and soldered wires to the distributor leads, and connected directly to the HEI. About 1 foot wire total for each lead. Are you using the original pickup wires from the dist to the HEI?
I didnt remove the distributor and i know timing isnt off. The original pickup wires are being used.
Looking at the HEI mount, running a ground wire fro the bolt (under the nut, touching metal sleeve on HEI) to the body would eliminate the bad ground potential.
As stated above, used a test lead to completely eliminate that possibility, but it seemed to have no effect.
Do you have a multi-meter? Check voltage to coil with ignition in "run" position. Also check it to the Module.
I'll double check that when i get a chance
Can you take a pic of the entire engine bay, showing where everything is, and how it is wired? Also, get a pic of the "hotwired" wiring.
I'll see what i can do there. I have the hei unit out of the car at the moment. Did a lot of testing yesterday and got too frustrated to put it back the way i had it
Are you 100% sure the distributor wire to the HEI are correct? They are easy to swap, and will cause this exact problem. I learned that the hard way!!! Maybe just swap those to wires, and try it?
Yep, tried swapping them just in case, no change.
