Weird battery light activity in 95 SC Auto... Help!!
So I was on my way home from work today and looked down to see the check gauge light was on (I was getting towards the 'E' on the fuel gauge. The low fuel light was on as well, so I thought this was normal. Several miles later, I look down and the check gauge light is now out, but the battery light was on! The car was running fine, no apparent problems noted. Towards the end of my 50 mile drive home, I was looking down and hit a bump, the light went out for a split second, then came back on. Still no problems with how it runs.
I stopped for gas on the way home, full tank, and get back in the car and the battery light is out. When I check the voltage at home, the idle voltage is 13.66-13.7, not changing at all when revving the engine. I have new terminals on the battery, the car starts and runs fine.
UPDATE: 3-15-2019: Light is back!!
So I don't think it is related to the fuel low light. I drove to work this morning and it came on as soon as I started it! Arghh! I did notice that when I revved the engine above around 2500rpm or so, it would go out. Or, if I was above 2100rpm-ish on the highway it would go out. I can sit there and watch it as I approach 2100rpm. It will start to flicker and then as soon as I hit that certain RPM, it goes out.
Yet, it still runs great! I am thinking maybe the voltage regulator on the alternator is going out. I doubt it is the original, have 172k miles on it (well, more than that as my odometer gear needs to be replaced as it isn't working).
Question is, if it is the alternator, knowing that the local parts stores sell mostly junk, I wonder if I should take it to a shop and get it rebuild / upgraded?
