3-Series (E21, E30)Chat relating to the BMW 3-Series from 1975-1983 and 1984-1991 line. Specific models: BMW 315, BMW 316, BMW 318, BMW 318i, BMW 320/4, BMW 320i, BMW 320/6, BMW 323i, BMW 320i. E30 Family models include: BMW 325e, BMW 325i, BMW 325is, BMW 325ix.
More specifically, when I turn the key to start, there's a very rapid clackclackclackclack until i stop turning the key. There's an audible metallic ring when I stop. The usual startup sounds are absent.
The dashboard lights are on when i turn the key, the radio turns on with the antenna raising itself, the headlights work though it dims slightly when i turn the key. Signal lights, brake lights, power windows all work.
Has anyone seen the problem symptoms before? Greatly appreciate any help.
you gotta understand how many amps a starter motor draws....tremendous, in fact, that is basically all the battery is there for, to engage the starter/solenoid motor, after the engine is running the car runs off of the altenator. the battery then is recharged via the altenator. 12 volts but the altenator puts out like 14.5 volts.....the extra 2.5 volts are there to recharge the discharged battery back to proper charge (amperage). Back in the day they had generators and regulators. If the regulator failed the generator would overcharge the battery and cause it to explode. The altenator addressed that issue. Truth, if the engine is actually running you can remove the battery altogether, done properly and the car won't even die.
Well, in reply to you both, I'll take a look at the battery first as it sounds the easiest to remedy/check. Will post back here again if the problem still can't be resolved, maybe with a video (if this forum allows links). Thanks a lot everyone.
Hi guys, it really was just a flat battery. Temporarily fixed for now. Thanks for the help.
