Crazy intermitent Electrial problems
Ok, I have a 92 F-150 300 I6, 4x4 that is all manual, and no AC. Over the last week I have been getting intermitent charging problems. I am not sure if it is possible that it is the Voltage Regulator or the Alt. or something else completely. Since it is intermitent I tried to describe the situation as best as I could. I have never been able to test the electrical while the problem was occurring.
I will start the truck up and it will run fine, then down the road the charing light will come on and my volts drop down, then a minute later it is running ok. The other thing that happens is I start it and the light is on, then a minute or so later it is running ok. The second time this happend I stopped and jiggled the wires on the alt. to see if it made a diffrence and the light went off. Later that day I tried again it it didn't work. It also didn't shut off for about 15 minutes.
When it happened and I had a free minute I took it to a parts store to have it checked out. I shut it off to go inside and get someone to test it but when I started it up there was no light and charging was fine. Later that day I drove it to columbus and it seem to be doing good till I stopped for gas and it was charging up around 16V judging by the dash gauge and where it normaly sits and where it was when the light was on. I didn't have any problems with anouther 45 min drive.
The last two days the light has come on again but either goes out with a small amount of driving or shuts off when I turn the truck off and turn it back on. It never seems effected by charging high or low but I figure charging high isn't good for the battery and low is either not enought to keep charging the battery or only running off the battery. Tonight I got in and it was low charging but when I gave it some gas it jumped to high voltage, then when I let off it jumped back and forth and dropped down again. When I reved it again it bouched a bit and stayed at around 14-15v.
Is the Voltage reg. part of the alt or seperate, I know you can get them seperate but if I get a new alt. will it come with one?
