I've been trying to cross reference, and I know there is someone here that has access to the Lexus database.

Can anyone confirm that the 2005-2007 GS430's all have the same housing for alternator?

I know part numbers are different, I just want to make sure housing are the same for the following years.

Trying to purchase a H/O alternator. The two compressors I have on my vehicle suck the life out of my car down to the 12.3v range

 

what compressor?

Maybe get them their own power source.

 

I'm sure it would still dip to the 12s, I'm using two viair 400 compressors.

 

oh, that compressor. LOL

aww... OEM for less problematic. Does the compressor turn on when the car is off?

 

well... while the car is on i'm getting 12.3v and close to 12v. I keep popping fuses and I don't want that hassle anymore. I know for a fact going from 14v down to 12.3v is very stressing on a system and alternator. So I'd rather fix it than bandaid it.

For now I think I will disconnect one compressor to take down the draw and order a Mechman alternator.

If anyone on here has the schematics of the alternator and knows how to measure how many amps are measured at idle, please LMK! Thank you!!

 

Did any information come up about the cross reference? Looking to replace my alternator.

 

I went ahead and purchased a mechman alternator (i believe it ran me 450+ at the time I was looking for alternators).

Haven't had a problem since. If you're not a heavy user like myself, I would just go with OEM alternators, or if your alternator is on its way out, I would look at changing the brushes on it (someone on here explains how to repair your own alternator rather than buy a new one, which costs, last i checked 500+).
