Hello Everyone,

Sorry if I posted this in the wrong place..First time on this site. I have a 1994 Toyota Pickup 22RE W/ Automatic Transmission and it's a bare bones truck. I got the dreaded battery and brake light combo and battery died. I have checked all grounds, used a known good battery and alternator just will not charge. My question is on most sites it wants to know if it is a 70AMP or 60AMP alternator, but I cannot tell which one I have. Someone told me that the 70 is for the Automatics, and the 60 is for standard transmissions while others have told me that the 70 is for a 4X4 and 60 being used on 2 wheel drives.

I tried the VIN decoder on this site and it shows as a 60AMP...So I am just asking if anyone else has ran into this and knows for sure? Other than that, I love the little YOTA and 260,XXX miles and going strong.

Thanks,
Jim

 

jimbo - many times with these alternators the issue is that the brushes are just worn completely down. Fairly certain that RockAuto (among others) sells the brushes for only a few bucks. I'd pull out the alternator and take the brush holder out and look at them.

Simple and easy thing to do to get some more life out of that factory Denso alternator.

Video on how to change the brushes:

 

Keep the Denso core as much as possible.
Second on inspecting/replacing/cleaning brushes. I was gonna do it on mine but local rebuilder reused a screw that the head is stripped so I could not disassemble anymore. I could have spent man-hours and $ finding extraction kit, and doing it and was still not sure the regulator was good because it had oil splatter, so I decided on Denso-Remanufactured in the U.S.A. from NAPA.
If you need replacement we have a thread on potential sources.

 

Always try replacing the graphite brush unit before anything with the Denso alternators. I just did my stock Sienna alternator at 220,000 miles. Was working fine, but did the work proactively. Once the alternator is out, it's like a 10 minute job to remove the brushes, clean up the messy bits, and then toss in the new brushes. The alternator shaft was a bit worn down but looks to have at least another 60,000-100,000 miles left on it if nothing else fails. Although, with the 22re engine, the alternator is a little more of a pain to get out than it was on my Sienna. If I recall on my 22re truck, the grunt work had to be done from under the truck with it lifted a bit.
