This is all way to confusing for me.
There is a I C regulator on side panel of truck that all wires are connected too.
Is this something that can be fixed or tested?
Not very good with cars . As you can read on>> trying to get some ideas for My nephew who is working on truck with not a lot of success
.
It is time for professional help. A hot rod shop might even be able to change the system to a modern alternator for a reasonable price.
Itās too late now but the next time you need help please start your own thread.
Ok, I think I see what you mean. The '82 2wd pickup with the 22R engine does seem to have the alternator voltage regulator separate from the alternator. Most vehicles these days include that part w/the alternator assāy. Even my late 70ās VW had that part inside the alternator. But the 22R alternator of that time period must have it separate, like my early 70ās Ford truck.
The diagram Iām looking at shows it located in the driverās side front wheel area. A part like that isnāt usually serviceable. Itās just replaced when it fails. As for testing, it is specād at 13.8-14.8 V, temperature 77 F. I presume that is the alternator output voltage range. So it can be measured at the battery posts w/the engine idling. Anything out of that range indicates either a faulty voltage regulator, faulty alternator, faulty battery, or problem in the carās electrical system.
You might want to visit the attached Toyota info, It shows the regulator as being incorporated into the alternator assembly.

I think that diagram might mean that part comes with the alternator when you buy one, but if you look at the voltage regulator in the diagram, you can see it has two holes used to bolt it somewhere, presumably other than actually on the alternator. The info Iām looking at says it is a separately replaceable part, 1/2 hour labor. I see no separate price for the item tho.
Nope. The diagram and part numbers are not from an aftermarket supplier. The diagram is Toyotaās exploded view drawing for the OEM alternator assembly. Itās the same one the Toyota parts guy uses to look up direct replacement parts. The part numbers referenced are Toyota part numbers, the assembly is the Toyota assembly.
Hereās another link that might be of help to the OP. The poster says āI have replaced my external regulator todayā, indicating that part is separately replaceable on the posterās 22R 1982 Yota pickup.

I have tried everything.
How do I check wiring to alternator to see if that is failing?
