I have a '96 XJ with an Optima deep cycle blue top and a Warn M8000 winch. Factory alternator with 87k miles.
I was winching my buddy out on a trail. It had a bunch of loose dirt which my tires spun around as I was backing up to get into an appropriate winching angle.
I winched him out, and it was all of maybe 2 or 3 minutes of serious winch use. During so I was revving up the engine to 3 or 4k. Afterwards I had noticed my GEN light came on beside the check engine light.
My battery gauge was reading a normal 13.5 volts. After seeing the light I turned everything off then drove home about 12 miles. The gauge stayed right at 13.5 volts the trip home.
After arriving home I turned the engine off and I restarted. Now the GEN light went away.
Any idea why the GEN light came on, but then went off on the next engine start? Do you think the loose dirt thrown at my alternator could have momentarly affected it?
