Over the winter I changed from a GM points distributor with a Digital 6A and Blaster 2 coil to using an HEI distributor with the same Digital 6A box. I removed the guts of the distributor and installed the wire harness to the 6A and changed the stock coil to the MSD in-cap coil (no room for the Blaster) and put on a Street Fire rotor & cap. Following the instructions with the coil I put in the low resistance button from last year (hardly any miles on it really). Ran the distributor center ground wire down to one of the bolts that was holding the original coil to the intake. Box was wired direct back to the battery with the MSD capacitor a few inches away from the box. Box is located behind the passenger wheel well several feet from the radio, but of course the radio is near the distributor (but down on the trans hump so not right behind it like on some cars).
Wires are Taylor Spiro-Pro, virtually new. Car seems to run fine, starts good, etc., but I've got a bad snap/pop/crackle on the radio now that wasn't there before. Happens regardless of the input (FM, CD, USB) and isn't a buzz that goes with the RPM just random snap and pops almost like you had a loose wire or something. The changes from last year were only the distributor which is really only the pickup button and coil as everything else is using the 6A box. Before I start randomly swapping parts, anyone have a logical test sequence they could suggest? I'm going to start with the coil ground wire to the coil frame as it had a black coating on it that maybe wasn't removed from the bolt eyelet, they maybe swap in the stock coil. After that I'm out of ideas. Thanks, M
