I just went through this with my 02. Obviously need to do the typical due diligence... check for bad relays, insecure wires, bad leads, any sort of corrosion or funniness around grounding points or on the connection from the battery to the starter. IIIRC the alternators on E30s are internally regulated (don’t quote me on that). If they are not then check that the voltage regulator hasn’t quit on you. If nothing shows up have the alternator tested as well as the battery. Not sure what size you are using and/or which cars the battery is known to work with, but it’s possible you’re not getting enough power to start the E30. However, the one thing that screams alternator to me, aside from having access to what is supposedly a good battery, is the fact that it’s doing nothing when you start it now (those last few attempts to turn it over may have been the alternator’s last remaining breaths). I had the same symptoms when my 02 decided to stop turning over and it ended up being a bad alternator (my installation of an overly enthusiastic audio system a week prior obviously didn’t help matters![emoji2957]). Sorry you’re having to deal with this. It can be a pain in the rear. I’m also sorry that I live on the East Coast and can’t give you a hand. I’ll cross my fingers that a local vintage BMW enthusiast and all-around good do’er will see this post and offer to come by and give you a hand... Good luck, Esty!!!
