Hey guys, I'm new to to this forum and comin here out of sheer desperation (my mopar's ignition has all but defeated me :angry4
. My 73 challenger with a 340 has the stock ignition setup. A few weeks ago, i started my car after a carb swap and all was well... For about 5 seconds. The motor shut off, and i discovered a broken fuse in the engine bay going to the bulkhead. After replacing the fuse, i was able to turn the motor over, but was not getting any spark. After a long 3 days replacing the coil, dist. Pickup and rotor, starter relay and ballast resistor, the problem turned out to be the ECU. replaced it with a blue ecu from O'riley's and all was well... Except for the battery not getting a charge from the alternator. So after replacing the alternator, i concluded that the voltage regulator must be at fault. I disconnected the battery, swapped in the new VR, and started the car. I gave it a bit of gas to warm the engine up (since how there is no choke) and She ran smoothly... For about 8 seconds before dying and blowing the fuse out in the engine bay. So i am back to square 1. Any suggestions?? Keep in mind that this is not a stock motor and it achieved max power at a 6500 rpm dyno run... Idk if that affects the stock ignition or not.
