My check gauges light has been randomly going on and off for about 8 months.
In the past month, I have noticed my headlights flickering at idle and when I turn off the Jeep, all of the accessories seem to lose a substantial amount of power. The gauges and head lights become very dim, and the fan barely works. It has no problems turning over, and I had the battery checked over the summer and it was good.
From what I understand, the TJ has a very reliable alternator, but from what I know, all the symptoms point to that. Any thoughts?
