Need assistance with Check Gauges Light
A few weeks ago I took my rig out to do some wheeling. Driving on the highway at 65 mph I got the Check Gauges Light. Gauges all looked good and it drove fine. I pulled off the highway and checked everything and it looked good. Light went off.
Today took it out wheeling again. Was out all day and the light came on again on the way home. Gauges all looked good except the voltmeter had some movement. It was wavering from just below 14 to just over 14 on the gauge. Everything else looked good.
I stopped by Autozone and the battery tested good. Rig runs great and has no issues other than occasionally taking a few seconds on the key to start up.
03 TJ Rubi with 78 k, auto tranny. Battery is a 18 month old yellow top Optima
Thanks for any help!
