Gotta be a ground issue. Please post your fix when you track it down. Remember patience is a virtue!!

Iím so glad I stumbled across your posting. I own a 1998 GMC Jimmy 4x4 with a 5-speed manual transmission and over 325,000 miles. Everything you described in your post has happened to my vehicle. My first occurrence was about 5 years ago. I was driving down the interstate at about 60mph, the tachometer moved erratically and then the gauge cluster lit up like a Christmas tree and the vehicleís engine shut down. I coasted to a stop and I was able to restart with no problems. Now the problem happens maybe once or twice a month, sometimes more and then it will go for a few months without occurring. I thought at one point I traced the problem to a bad multifunction switch. When I engage my turn signal, the battery meter fluctuates. When the vehicle was new this never happened, but this started maybe 8 years ago. Once I engaged and kept the left turn signal on because I thought that was the culprit. The battery gauge began pulsating to the left and went lower and lower until the engine cut off. Sometimes when driving, I can somehow halt an engine shutdown if I catch the battery meter slowly moving to the left. I just manipulate different settings on the multifunction switch and somehow the battery gauge pops back to normal, but sometimes things are inevitable and once the battery gauge gets to a low enough number, the engine dies. Iíve been told by someone that there may be a grounding issue somewhere, but everything looks fine. Other than this problem, my vehicle, like yours, runs fine. I just replaced my alternator, but the problem remains. I own an Auto Zone gold battery.

What do you or anyone else think is the problem?

Default Alternator issues

Ok I bought my 2000 Silverado and it came with two of the off brand kcs you can buy at autozone. They worked but wanted more light since they were halogen. Bought 2 more and hooked them all to 1 wire going to the alternator. Now since they have been hooked up my voltage twitches from 16 to 14. So I unhooked the lights and tried it again. Still twitches. I believe it's a ground wire. What's your thoughts ?
