OK, as I was driving around today, I noticed my alternator light flash on periodically, though it never stayed on for more than a few seconds. Later, the light came on and stayed on but only when the RPM was above idle. The wierd thing is, when the light comes on the needle on the volt meter goes right to the top of the gage, the dash lights brighten and the console heater fan speeds up (due to the increased voltage i guess).
The alternator was new in July, so it seems a little early to be having problems with it, and what would cause the voltage to increase past normal? Is the voltage regulator built in on these alternators? I'm at a loss here so any help would be great. The truck is an '85 4Runner, 22RE.

If it was new last summer then you should still have some kind of warranty, have them check it out.

OK Dan, I guess I shouldn't have said ANY help... besides, the muffler bearings are ok, I even checked the exhaust solenoid


Yeah I figured I'd have to do a warranty return on it, I was just hoping I could find the problem easier than that. And Im sure I still have all the paperwork from when I bought it...

Another question now, this morning when I went to start the truck up, the battery was completely dead. Not even enough power to fully illuminate the clock.
I can exchange my alternator for a new one no prob, but that makes me wonder if thats the real probelm. Would a faulty regulator drain the battery like that, or is it likely that something else is shorting out?
Hmmm, I hope my truck isnt going to catch fire...

it is an internally regulated alternator, and sounds like the regulator is the problem, and yes it could drain your battery. you dont want to drive around with it like that for too long, you`ll slowly blow all the lights in your truck.

there are two types of alternators for the toyotas one is a revers ground the outher is normal.make sure you have the proper one for the wireing system,not too maney peple know about this besides toyota,and they really dont like to hand out the info
,to see if altereator no work and have truck runnin
disconect positive batery if truck die alternator no work, check brushes verry easy
if in good shape and armature is in good shape and then go to regulator,one on sidefender or in /on altinator. you can replace it or read a book on how to test it,if fail replace
but verry easy

Cool, thanks alot. I didnt know there were two types of altinators. Im just relying on the fact that Lordco gave me the correct one. I just picked up a fresh one because it was still under warranty, so this one better work. Haven't installed it yet though.
