It cold be a bad gauge or a wire that is shorting causing this. Also check your battery for condition including load test. Most auto parts do that for free. Did you replace the tensioner when your replaced the belt. It should have been

No I didn't change the tensioner. It looked good to me. It just did something new to me now. I was driving it and the car just automatically shut off. It never dos that before. I had the battwty tested like 4 times cause its atleast 5 years old. So my first thought the battery was bad. I checked thw voltage with the car running. It was 1475 steady.

That is only what the alternator is putting out have the battery tested including load test. Auto parts do it for free being a 92 chck yoru fusible links at starter they may be broken or partially broken causing this. Without actually seeing this it is very hard for me to give a proper diagnosis. See pic

They dont look bad. The wires don't look fraided or cracked. And the cover of the fuse dosent open up. I don't believe its suppose too. It says 16 on it. Which I'm guessing thats the ampage. Those fuseable links are not like the fuseable links for a car stereo. The reason I'm so lost is this is the first time I have ever worked on a car with fuseable links.
