2002 Camry V6 High Output Alternator

[Rajeev]

Hello,

I had an Ohio Gen. 180A alternator installed in my 2002 V6 but it doesn't charge at idle (600RPM) only at 1000RPM or greater. So, Ohio Gen. attempted to mod. with a reduction in pulley size, which technically should've been 10:6, but anyway this did not help much at all.

So, I asked my shop to order a Stinger alternator, but they told me that Stinger does not make an alternator for my car (?). Anybody have installed a high output alternator in their Gen5 V6, and works properly?
Thanks for any info.

Are you saying that the alternator has to be turning at 1000 rpm? If so, how are you determining that it is only turning at 600 rpm? I suspect you are basing the rpm off of the engine rpm which won't be the same as the rpm at the alternator. Is the pulley on the HO alternator larger then the stock one? If so, thats your problem.

Yes, I meant engine RPM. With their pulley size change, now it's maybe charging around 900 RPM. That's a good point about comparing my stock to their the Ohio Gen. I'll have to take it in to the shop as they have my stock now. I'm assuming it's the same right now, as Ohio Gen. should have gotten the correct specs to make the alternator.

But there are several things I'm unhappy with the Ohio Gen. alternator:

1) It only has ONE mounting point on the casing? What?? It is supposed to have 2. and now there's no belt tension adjuster.

2) If they have to put an even smaller pulley then it's going to reduce my mileage for nothing really. (I felt the difference of the smaller pulley already) And at higher engine RPMs, it will create excessive heat and wear on the alternator.

3) There's no direct connection for 0 gauge power and ground

4) Alternator only maintains 14.1V @ 1500-2K engine RPM, instead of 14.4V

5) When I called Ohio gen tech staff they tell me it's fine that it doesn't charge at idle, and recommend I install a 2nd battery (well, i did have a 2nd Optima Yellow top from my other car so now it's installed) , but that's not the solution.

I had a Stinger 200A alternator in my Gen3 2.2L w/o all these problems.

Yes, I was hoping Ohio Gen. could do those things, but apparently they're not willing. I just bought the alternator from them, through a shop of course.
So, I would think they should be taking care of any mods since it's not working properly.

So, I'm running Harrison Labs 800Wx2, Infinity Beta 1000Wx1, PPI 125Wx4, and 1F cap w/ some possible upgrades if I get my alternator working properly. These ran fine in my Gen3 w/ Stinger 200A alternator.
