OK, its been a while since Ive been on this site, you've helped me before so "fingers crossed". RX300, 2002, FWD, same engine, same tranny, same everything. 250K. Lent the car to the girlfriend, dead battery ... charged the battery but the "charging circuit light" stays on. Havent done anything other than made sure the drive belt is on. Ive got the 2002 Lexus Repair manual "the bible", it details removing and repairing the generator and a bunch of electrical tests. Connected a "code reader", no codes... snafu. Im about to start making electrical measurements. Any words of wisdom guys?
