O.K. I need a little help here. I purchased a used 82 Toyota 4x4 a year or so ago. The truck has the 22r and a 4 speed. When I bought the truck it was evidently having charging problems. Someone rigged up a switch to the alternator to make it charge. At some point it quit working. I haven't left the house with the truck since buying it. Other than to pull the neighbors truck out of a ditch and the short trip to the store. The alternator and regulator were new. The guy I bought the truck from said he put the alternator and regulator on the truck after it quit charging but it still wouldn't charge on its own so a freind installed the switch. I took the alternator off and carried it to AutoZone and it checked bad. It was a lifetime warranty so they replaced it. Here is my question to you all. What could cause the charging system to stop working in the first place? What should I look for before trying the new alternator. There are no shorts that I can tell. I don't see any sort of fusible link or fuse that is or could have went bad. Maybe one of you have had a similar problem.
