so a couple months back I installed a new Summit HEI distrubutor , , I changed out the Ignition module with an MSD module from the previous old distributor. As of lately when i turn the ignition key to the on postion it sounds like the distributor is arcing. It starts slow and then speeds up to a stop. if I turn the key to start the car it starts fine and seems to run fine. This doesn't happen everytime, probably 1 in 6.
anyone ever heard anything like this ? if I take the cap off , no noise. I put the new module that came in the distributor back in and it still makes the same noise
also maybe unreleated but lately my battery has been dead but on a battery tender. and I added a couple headlight relays...
