Been having the issue for a while but its been slow to try and fix due to lack if funds as im sure everyone here is familiar with. While driving everything seems fune at first then lights guages will shut off and then on like they suddenly lost power then regained it. First i thought it was the alt which was replaced as well as putting in a new battery. Everything was fine then it happened again. Justin came out and pointed out the diagram i had looked at when hooking the fd alt back up was wrong and showed me how to do it right. So got another new alt and new battery but aftr about 10-15 min of driving it happened again. So long story short its not the alt or the battery and i have no idea about where to start with electrical from here. Has anyone else had this problem or know how to fix it?

 

Nobody has any ideas? Cause i sure dont

 

Maybe you're tripping a breaker. Does the car lose all power completely? Does the power come back immediately? Does it happen when you go over a bump?

Might be a bad connection. Have you checked the grounds and the fuses?

 

Its when normally driving and it seems to shut of the unnecessary stuff first like radio and extra guages only loses power if i ignore it and the fuses were fine when i checked.

 

clean of your grounds. theres one by the battery, one on top of one of the rotor housings, and one by the firewall. i think theres one more somewhere

Yeah I had the same issue or something very similar. Turned out that the wire (the B terminal I believe) wasn't connected properly and would shake loose making me loose all power once the battery was drained, or if the battery was drained already once it shook loose the car lost power like you described.

I would also advise on checking all your grounds as well too.
