Alternator R/R-Gaskets
Looks like I have the flickering lights, bouncing amp meter gauge syndrome. I did a test on the alternator and it appears to be bad. I just R/R'ed the plenum for a tuneup and replacement of some bad injectors. The plenum has been on only one week. Would I need to get new plenum gaskets, again? or can I carefully lift the plenum, do the alternator swap and reuse the gaskets? Any recommendations on Alternators or should I try to rebuild it and the voltage regulator?
Thanks, Dave |

I changed the one on the 90 I used to have and only removed the horn from the front of the TB

Re: Alternator R/R-Gaskets
Mine quit while on a cross country trip. Like We Gone the mechanic was able to replace it by removing the front section. Be careful there is a gasket there also.
Good Luck

Re: Alternator R/R-Gaskets
I just took the air horn off (carefully), took the bolts out of both brackets and removed them completely from the engine. Then came the oil sensor. It has to be removed with an extra long 27mm socket. The correct tool would make it a snap, but some channel locks were just enough to loosen it to take it out by hand. Disconnected all the wiring and out it came from the front. Thanks for the suggestions.
 I hope this fixes the flickering and the bouncing voltmeter.  We shall see!

Re: Alternator R/R-Gaskets
Ok, had the alternator bench tested and it tested GOOD. Great, now I'm an expert at alternator R/R.
 So, to add to the indications... the flickering lights are now not flickering - they are out completely. When the ignition switch is turned ON the system goes through it's preparatory sequence and the dash instruments are bright as usual, but when they are suppose to go to the dim normal intensity after the sequence they all go out!  The car does run. Am I now looking for the elusive Body Control Module or Central Control Module as its listed in the manual? Hummmmm... Suggestions. Thanks Dave

Re: Alternator R/R-Gaskets
Are you noticing the problem while in the garage? This got my attention also, it was the ambient light in the garage was to low. Does the dash light up when you turn the head lights on? If so try this, With the head lights off shine a flash light into the light sensor. On my ’90 it is just to the left of the words “trip monitor†on the IP. I hope this is all it is.
Good Luck |
