7.3 IDI charging problems
well, thanks for all the ideas guys. and the discussions. I have no idea what the problem was, but it fixed itself after buying yet another voltage regulator on ebay. I guess the autozone and advance auto parts voltage regulators are crap.- Dr. Magnus

7.3 IDI charging problems
hm, something I just noticed. if I take a voltage reading from the battery, it reads lower than if I take it directly from the alt. I think i'm going to explore the wiring again tomorrow. another question though. my batteries are not that old, but is it possible that a bad battery could be...- Dr. Magnus

7.3 IDI charging problems
I already have a solid state voltage regulator, I was wondering if the mechanical ones provide better performance. But seeing as this ebay listing is so cheap, I'll go ahead and pick this one up. Maybe the ones at autozone are just crap.- Dr. Magnus

7.3 IDI charging problems
:/ everyone is saying that the G3 alt is the way to go, problem is, I just don't have the cash or the time right now to make that swap. I might in the future if i can't solve this problem. Plus, I KNOW that this alternator can supply enough power. It seems to me that the stock voltage regulator...- Dr. Magnus

7.3 IDI charging problems
The situation seems to have changed a bit. Now if I keep all loads off the electrics then it will charge at a happy 14.5 volts, and idling it will stay at about 13. BUT that is with all loads off. Yesterday I was careful about not using the AC before I turn the truck off for the day and I was...- Dr. Magnus

7.3 IDI charging problems
:/ the problem is I just don't have the cash or time to do that right now. All the replacements I have had have been covered under warranty. I was hoping maybe there is some wore or something I could replace to fix this. But if that is the only option I guess I will have to live without AC this...- Dr. Magnus

7.3 IDI charging problems
the problem with that is the batteries don't start charging until roughly 1200 rpm, so thats right out. but that may make a good temporary fix. I have to take the truck out tonight, so i will see how it behaves.- Dr. Magnus

7.3 IDI charging problems
Ah yes, it's a 1989 f250 standard cab with a ZF5 transmission. The main problem I'm having with this is the fact that driving around town with the truck in this condition with the AC on, my battery will not charge. With the AC on at idle the voltage drops enough to not charge he batteries, and...- Dr. Magnus

7.3 IDI charging problems
The battery cables are relatively new, and corrosion free. It seems that the previous owner replaced them before I bought the truck. but I did have to replace one of the negative battery terminals because the terminal was too loose on the battery. the truck starts just fine when the batteries...- Dr. Magnus

7.3 IDI charging problems
Ok, so the best way to do this is probably to explain everything from the beginning. I bought my truck about 3 1/2 years ago now, and since then It has haunted me with the same problem. It started about a month after I bought the truck, I had replaced the alternator with a new one as the old one...- Dr. Magnus

89' ford f250
Ok, so I just bought my 7.3 f250 a couple months ago for $2000. I though "Yeah! motor runs nice, and this truck has a rep for being extremely reliable" little did i know, the previous owner had really only taken care of the motor and nothing else. He told me that the clutch was new, but...- Dr. Magnus
