Blowing Alternators

You can also order a brush set from Toyota for around 25 dollars and instal them yourself. And save some money.

As long as you have a Japan spec Phillips screwdriver it’s easy.

Is there a part number for that set?
 
Do you know which Alt you have?

I think the 27370 number is a fully loaded 70a.

Edit: the two part numbers before the last number are the OEM and Denso part numbers for the Alternator. I’m pretty sure it’s for the 70a Alt. The 80a Alt is totally different.

Good info. Are the bearings that come with the Maniac kits made in China? Guessing that's why you have the other part numbers listed. I always assumed they were and just bought rebuilt Denso alternators

I'm still amazed that my original one still works....It might help to take apart the broken one and figure out why it is failing. I think there is a diode in there that you can check with a multimeter.

Electrical problems are not fun. What happened to the other car?

The Manaic kit I used just for the VR. It was made in China. Didn’t feel like spending over 100 dollars for an OEM or napa voltage regulator for the sake of troubleshooting. The VR is still going strong. The problem ended up being a bad diode in the bridge…..

Well, almost a year in on the Denso Alternator and we are still going strong. I will add my voice to the others that stated the parts house alternators just are not good. Save yourself time and buy a Denso.
