Had this issue 3 times where the voltage gauge drops, check engine light comes on and engine dies. 2000 XJ, 4.0, AGM battery.
One was last fall winching through some snow. We sat for awhile, popped the hood and started checking various things. After 15 minutes tried the key and noticed the gauge was reading around 10 volts, it had come up. Sit a bit longer and came up to 14 volts. Started up and turned around and drove home 45 minutes, no issues.
Same thing happened this weekend. After about 45 minutes of slower speed trail running Jeep died. Let it sit and took a hike around, after about 15 minutes started back up and drove another hour at moderate to highway speed with no issues. Noticed the battery was warm/hot this time around.
Happened once more that afternoon under similar slower speed conditions. Noticed the battery was hot to the touch and realized the upper coolant hose is resting on the forward edge of the battery. Found a stick to put between the hose and battery.
Dumped a bottle of water over the battery, cooled it down and started right up and drove home, about 1 hour no issues.
So anyone had this issue? Is the battery temp sensor going wonky or s the coolant hose transferring to much heat into the battery?
