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.

Maybe show a link to the upgrade 

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..

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.

"Mopies", you gotta love that one. @W-T 's ground mod is definitely worth the effort.

With my AC on full-blast and stereo I'm at .025vac and with everything off .018 before this mod I was at .035 with everything off. Definitely worth it

I started calling him that when I first programmed his phone into my contacts. Somehow Mopar Mike morphed into 'Mopies' while thinking about my visit there..... things was a little laid back, sort a like no measure of a clock nor time, living up in those mountains. 

 

But he's the fastest VP changer in the west.

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 believe diodes are designed in amps or something like that, so if you use hi amp upgrade these diodes from store on this site may not be strong enough. They will work with stock Denso and not Bosch. Unless you really need more amps I would just replace diodes for now or buy a whole new alternator that's ready to go.

Hit the nail on the head. Stock alternator is only 140 Amps. Even at that its possible ot overheat stock diodes with extended grid heater usage. Now increase the size of the alternator and you'll burn out the stock diode pack quicker. 

 

I've been hunting for oversized diodes for a long time that in the 180 amp realm. I've even called Nations and few other attempting to buy just the high current diodes from upgrade alternator to solve the AC noise issue. So far the best I could do is stock 140 Amp diode at least so people could rebuild there own alternators at a fraction of buying a chain store alternator that might fail.

 

Mike,

 

I just placed an order for your Denso diode.

 

Thanks!
