I just completed installation and tuning of my newly rebuilt motor. Here’s the background: 74 base model. I re-stroked my 1.8 liter to 2.0L and kept the 1.8 L head. Also kept the 320i distributor and ignition module. This seems like a nice setup and runs like a champ. Huge improvement over what I had... Here’s the issue: occasionally and seemingly completely at random, my electrical light will begin to glow faintly. It doesn’t seem load related- can happen no matter what accessories and lights are on (or off), it can occur at any time and generally sticks around for a little while then magically disappears for no apparent reason. There’s no perceptible effect on engine performance while this is happening. I’m stumped. I’ve checked connections several times, and all looks good. I’ve cleaned every ground I can find. Alternator(e21) is new and charging system is in good order, though I haven’t metered it while this is actually happening. New alternator belt in place. Any 02/e/21 electrical gurus out there want to take a guess? I’m leaning towards something to do with the ignition module, though I’m using the same module and distributor as before and there was no issue like this previously) Another possiblility is just that something’s damp? Its been INCREDIBLY wet here in the PNW recently, maybe this will go away if it ever stops raining. I guess I’m not too concerned about this but I’d love to have a clue what’s going on. Thanks all, in advance.
