Alternator help for ‘80 Saudi FJ43

[Widow61]

Noticed on my drive to work this morning that my battery voltage was slowly dropping. Made it home all right but voltage was well below 10v when I parked. I’m assuming it is my alternator not charging anymore. The battery is about a year and a half old.

This 1980 FJ43 came from Saudi Arabia last year and definitely has some middle eastern wiring issues. I need help finding a replacement alternator. The alternator mounts to the left side of the engine below the intake.

There is a sticker on the alternator labeling it as a Hatec HC-27020-xxxxx. The back half of the label is missing. Do I need to replace the voltage regulator too? Any ideas on finding a replacement? Any help is greatly appreciated, Scott

Maybe you only need the voltage regulator. It could also only need the contacts cleaned.

For me, I just bought a GM one wire 105 Amp alternator off Amoron for $70. I'll monitor the voltage instead of amps.

Can you have the alternator bench tested to make sure it is functioning properly?
My 1981 FJ43 has the alt in the same place and I haven’t thought about what to do if a replacement is needed?
I replaced my working voltage regulator just for the heck of it because it was from 1981. Toyota sells new exact replacements.
If you want you can have my working OEM VR for the price of shipping. Let me know.
