New Mallory Distributor, no spark, and 2 hours later
« on: March 20, 2013, 06:44:58 AM »
Just switched from points to HEI and went to start engine and test out everything at home before hitting the lake for more testing and found out I had no spark. Rechecked all my wiring and I had my 12 volts to power plug on cap. So I ohmed out everything wires and coil to cap all good. Tried a used known good modual same. Removed dist and checked the "hall effect sensor" by rotating dist gear, checked out ok.  :banghead: After calling Mallory every name in the book I noticed the new coil was painted black then it dawns on me the coil isnt grounding because of the black paint and on a stock coil it has no paint plus the internal ground wire on a stock GM has a star washer built into it and the Mallory doesnt. So I sanded off the paint on the 2 contact points for the ground wire and the ground bar and rechecked for spark wholla spark. I also ditched the stupid coil top that came with the dist and went with the stock GM coil cover, makes it way easier to work on for future use. Was so pissed yesterday I could of thrown a 100 yard pass with the dist. But overall went to bed happy. In the future what Im going to do is wire in a relay for the HEI to get direct battery voltage to it just make sure I have as much voltage to it as possible and get a star washer for the ground inside the cap. I'm doing the relay because I understand lower voltage kills these things along with poor grounds.
Just figured I'd share this for others if they ever have this problem.
