Started the other day and it's been squeaking a bit, I'm assuming the bearings are going out and I'm don't want to pay $100+ for a parts store special. 

 

Are the rebuild kits from genos garage good? And how do I tell if I have the denso or Bosch brand alternator? 

 

Thanks.

We sell the Denso alternator diodes... This will give you a clue. Bosch diodes are soldered in.

I didnt know that, But that helps! I'll be looking closer at mine when I get home from town to find out which I have.

All my trucks I've had over the years the tag was still on it telling what brand the alternator is.

Actually ended up ordering the hi-amp rebuild kit from them, I'll build and leave feedback on the post.

So just wanted to give an update, I did order a kit from http://rebuilderinabox.com/ for the denso and put it on Thursday, when I got out of work Friday I drove 20hrs non stop to San Diego and the alternator hasn't made a sound or had any charging issues. 

Glad I did the bearings, the ones I pulled out where on there last leg.

That was one of the things I wanted to do was source out the parts for doing alternator rebuild kits for the website. One of the many things no longer sold in a normal part store.

I performed the ground and positive cable mod on my Cummins and it didn't make a difference in my new torque converter lock/unlock issue. My alternator is putting out too much noise and I want to replace it before it burns up my billet torque converter and anything else electronic.

 

Can someone post the part number for the Denso diode kit, and the hi amp alternator upgrade? I was looking on their site for my 99 Cummins alternator, but then the one page said no kit and no price.

 

Thanks!

This site sells the heavy duty diode bridge replacement for the Denso alternator. Just click the store at the top of the forum page.

That's a great price for the diode kit. 

 

I finally found the upgrade section. What's everyone's thoughts on installing the high amp upgrade on our alternators when we install the new diode kit?

One or the other... Can't do both. If you update to high amp alternator you cannot use our diode kit. Diode kit only fits the stock Denso alternators. Bosch alternator has solder in diodes. 

 

There is a few members here that opted for high amp alternators to hopefully get away from the issues. Unknown if it has resolved the AC noise issue for most are just getting started in mileage and time.

I have the Denso alternator on my pickup. So I can't replace the diode with your kit and upgrade the amps on my alternator, it has to be one or the other?

The diode kit does not upgrade the amperage of the alternator. You need a new higher amp alternator to do that.

Mike said in his post above, that I couldn't install his diode kit and the high amp upgrade on my Denso alternator, he said it had to be one or the other. 

 

I just wanted clarification if that was correct or not.

I googled it and sure enough there high amp upgrades for the Denso. The one I saw was around $70 for the new stator and front cover. I just cant seem to link it. 

It seems to me with that and $55 for diodes then whatever for brushes bearings and such you would be pushing $175 plus your labor. I think I would just buy a new one.

 

 Since I have shown electrically challenge arse enough, I think i will go back to my corner.:sofa:.

I had seen the diode kits at Larryb's .

 

I pulled my alt to have a Local Small business strictly alternator / starter shop check the diodes etc.

So I just let him replace the diode pack and brushes and re test. IIRC it was less than ordering fron LarryB's and  he also gave me a year guaranty

I have the diode Bridge from 'Mopies Auto Parts'. Thats Michael Nelson, BTW, that owns this site. 

 

Just today I ordered the alternator rebuild kit from Genos Garage. I need to get my A/C noise level to acceptable levels now that I successfully replaced my VP44. It had a damaged PCU board, (error code 1688). Next I need to fully do the W-T grounding mods that are being reported a big benefit too.
