Searched and found a few other similar posts, but nobody posted if it fixed it.

Basically, I'll be driving and the voltage gauge will spike to 19. The Check gauges light will come on. Sometimes it will correct itself, but not always. Generally if I shut it off, it won't start. I get nothing, no gauges, etc... clock resets. Sometimes I was able to get it back by shifting into neutral, drive and back to park. All the sudden the gauges would come back.
I can usually jump start it to get it going again. Yesterday, I pulled the battery cables and cleaned the terminals, and it fired right up. Drove it around, re-started it. No problem. Got 1/2 way to work this morning (4 miles) and the gauge spiked again. Shut it off at work. No start.
In other posts people have speculated about the alternator/voltage regulator or a ground problem. I'm assuming I should check the ground first as it's easier. Is it located in the same place as a CJ with the 4.2 (passenger side motor mount?).
Cables look OK. Replace? Pull the alternator and have it checked, or can someone check it without having to pull it?

Battery is maybe 2 years old? Cables & alternator have never been replaced.
