[200q20v] Alternator Idiot Light

[Derek Pulvino]

Dave,

Thanks for your input, but I'm pretty confident the alternator is Aok.  The reason I think it might be wiring is I recently removed the alternator from the vehicle, and it was working fine before reinstall.  Also, lights work fine with car running or not, and once the voltmeter indicates the vehicle is up to the correct voltage, it stays there with no fluctuation.

the brake lite circuits are activated when the voltage goes low....i am
installing a rebuilt alternator tonite to correct this issue with my car.
i verified that the alternator was the culprit...alt/gen usually go
intermittent before they fail out right in my experience... although this
last time it just died....your issue sounds like failing
alt/gen....although there could be some large scale short or voltage
regulator issue that is intermittent that is bringing you voltage low....(
or maybe you shouldn't have installed 1500 amps worth of stereo upgrades to
get that good sound and kicking bass response  ;-)...germanautoparts.com
(adirondack auto brokers) had right one in stock..bosch rebuild for $210
plus core which was the best price i could find, non bosch rebuilds are
cheaper....AL179x i believe is the part # for the 110 amp unit

there cars?  I am experiencing that phenomenom right now, and along witht
the alternator light coming on, ABS off light, and parking brake are also
coming on and staying on.  Voltmeter shows the system to be running at 13.5
volts or so (after reving up the engine), and the ABS is working.  Someone
suggested it might be a function of having attached some wires to the back
of the alternator incorrectly, but wanted to see if anyone else had some
experience with this before I go hunt and peck.
