I was on a big adventure last weekend with the FJ60 (going to the dump) and I noticed that the voltage meter was reading low (below 12V around 10V I guess). As typical the voltage dips when the turn indicators were on, so I suppose the meter is OK. There was no charge light, though. But I did stop, shut off the engine and turned the key to run, without starting the engine. Still no charge light, so maybe the bulb is bad.
I ran through the trouble shooting from the 2F engine manual: Charge fuse seems OK. I do have battery voltage through the harness to the green connector. At terminal L, I read more than 2V, almost battery voltage. I have continuity across terminals L and F on the alternator with the key off. With the regulator installed on the alternator there is contiunity. with the regulator removed there is NO continuity at the regulator but there is continuity on the alternator. I believe this indicates the regulator is bad.
This is a replacement (rebuilt) alternator that I got at a local parts place probably 15 to 20 years ago. I remember I had to have it clocked because the regulator was in the wrong position.
I guess I'm looking for confirmation and suggestions how to proceed. I see @ToyotaMatt has some NOS IC regulator(s), but should I also consider replacing the alternator--either getting some NOS bling or go with another rebuild. We just moved into a new house and haven't sold the old one yet, so I'm not in a position to spend too much (without feeling guilty ).
Thanks!
