i dunno what model you have....i see u have a 99 but do u have the gs300 or gs400?

if its the 400 i have a alternator off my 2001 gs430 i could sell you for the lo lo (i think this will work for your V8 also) thats in good condition i took off for my aftermarket alternator

With the car on, should be 13.2-14.5. With the car off should no less than 12.6 after a few minutes.

hey john, if i'm averaging 11.3 out of 12.6 should i be worried? I'm unsure about the accuracy of the cap, b/c i've seen it fluctuate in .5 swings regularly.
