I have a 1998 Buick LeSabre. It's Fully Gauged.
The Alternator Gauge normally runs at just over 13. Now that it's got Cold here in Minnesota the Gauge at Times shows much higher than 13.
The Gauge Limit is 18, next number shown is 13, so I'm guessing Red-Line starts around 16 and ends at 18.
On Cold Starts the Gauge shows at a fraction below the Start of Red-Line, 16ish ? It never use to show that high during Summer.
Sometimes it may take hours for it to fall back to just over 13 (the normal shown all Summer)
Some Weird Actions as well:
I deliver Pizza. If I leave the car running at all times, even when inside the Store, if it's been running long enough so the Water Temp gauge gets up to around 200 making the entire car inside and out toasty warm, then the Gauge will drop back to Normal 13ish. When I then go on delivery and the Water Cools, the Alternator Gauge will immediately climb back to Red-Line.
Also, for the First Time a couple days ago, I noticed a very noticeable Dimming of my Headlights, a Glance at the Alternator Gauge showed under-13, was there for only a few seconds then went back above 13 and the Lights re-brightened.
Please help in the Diagnosis of this problem.
Thanks
