I have 1992 F350 Crew Cab 4x4 XLT with just a hair over 336000 miles. I've been having a charging system issues. Back in Feb I replaced both batteries. About later the voltage regulator went out. I replaced it with BWD Select from O'Reilly. Shortly after that the alt went. I put a reman from O'Reilly. Since then I've had a overcharging issue and then a no charge issue. Took it an alt repair place and was told the was bad. Went got a replacement for it. After that no issues for about a month or 2. Then ended up with it not charging again. Took her back alt place, and said regulator this time. I replaced, and went through all the wiring and such couldn't find anything wrong with that. About a week ago it started over charging. I didn't get chance to mess with do to a injury. Today I put a new regulator in it. Go about 5 miles down the road and starts over charging again. Now I moved the mounting spot for the regulator. It does have a ground. At this point I don't know what to do besides taking it to a shop. I want to avoid it but I figured is ask here first. This is what it looks like going down the road as soon as left up on the petal it goes back to normal.
