This could be a newbie question. I did search.

Saw a high output alternator for 4runners and tacomas that says it has 160 amp capability. How can I tell if I have a regular alt or a high output already installed? I don't have any guages that tell me how many amps or volts I'm using. Is there a certain part number I should be looking for without actually removing my alternator?

 

I was under the impression that 3rd gens had either a 70 or 80 amp alternator. Off topic but, did you swap the e-locker into your 01?

 

Is it a factory alternator? IE does it have the factory part numbers on the casing??

 

even if its a rebuilt alternator, you wont notice the physical differences. so, you wont know unless you track down the internals. btw, there are several components replaced to give a higher current output.

 

E-locker was there when I bought it. Looks like a factory job, even though I read somewhere they stopped offering that as an option for '01 4runners.

It says toyota on it. The only numbers I can make out are ?????-62160. I wasn't sure if perhaps there was a factory option for a high output alt or something.
