battery light comes on at idle

id have the alt bench tested....any good reputable generator shop should tell you if its going bad or not

my battery light came on about 2 years ago, charging voltage was real low, swapped in a new autozone alternator good to go

If raising the idle just a hair (toeing the gas pedal) makes the light go off, I'd recheck the idle. The 94-95 cam idles really smooth - I've run my idle down well below the commanded value (to about 500 RPM) and it was smooth as can be.

In my case, I didnt perceive an issue with the idle being lower (the stock tach is too inaccurate and the car idles smooth anyhow), so it was using a diagnostic tach and simply raising the idle a little bit that helped me. Plain and simple. Not that any of that applies to you - it's just what I figured out and how I fixed it on mine, in case it helps a little.


Other things to check: Peel back the regulator wiring loom at the alternator. The heat under the low SN hood vulcanizes the insulation bad (I had bare regulator wires sitting next to eachother inside the loom. The insulation had baked and fallen off). Those wires are voltage sensitive, so having them clean and completely functional is imperative.

Do take a look at the stock charge cable - it's kind of a POS. I chose to replace mine with new 4 AWG cable (that stocker looked like it was maybe 6 AWG. Mine was droppin 400 mV, which is not acceptable personally). This will likely not be related to your issue but is just good to do.

And check the power distribution box connection (where your charge cable connects to the underhood fusebox, along with the positive battery cable). That connection can be troublesome on 94-95's.

I'd really double check that idle and note if adding 100 RPM or so with your foot on the gas helps. If so, a gas reformulation (winter blend) or some sensory input for colder weather is likely afoot.

Random thoughts. Good luck.
