1988 318i - revs up, lights dim. Que pasa?
Hi All
I have an '88 318i (UK spec, right-hand drive, lives in the UK) with some kind of alternator/electrical fault. A few weeks ago, the thing died late at night on a dark road. RAC turned out, diagnosed a blown alternator regulator and towed me home. Garage confirmed and sent the alternator for repair. Last weekend, same thing. Different RAC guy, same diagnosis. He pulled the regulator on the spot and found a brush missing. Fitted a new one, but now I have a weird fault: when I rev the engine over 2500 rpm, the lights go dim, and the handbrake, oil and battery idiot lights flicker. Presumably it's still a regulator issue, but what? I'd expect a faulty alternator/regulator to result in dim lights at LOW revs, not high revs. I don't know if it's only happening when the lights are on, as (I guess) there's not enough load when they're off to manifest the fault. Anyone have an explaation/solution? Cheers, Peter |

I dunno how he diagnosed that without stripping the alternator and testing the various components. An informed guess would have been rather more accurate than a diagnosis. > Garage > confirmed and sent the alternator for repair. Right. Didn't they offer you a maker's exchange one? > Last weekend, same thing. Different RAC guy, same diagnosis. He pulled > the regulator on the spot and found a brush missing.

If the brushes or slip rings are iffy, this *might* manifest itself at higher revs. I'd go for a good make re-con. Try your local motor factors. Sounds like the repair you had done was more of a bodge. -- *No word in the English language rhymes with month, orange, silver,purple Dave Plowman London SW To e-mail, change noise into sound. |
