Hi, i'm new to this forum and i am here to get informations about the GS400.

They seem to have problems with the accessories that drains the power of the battery. I own a 1999 GS400 and mine is having a battery drain issue. After some verifications, i can confirm that the power is drained from one of the accessories/relay inside the car and that all the "exterior" wiring is fine. I can't leave the car for the night without disconnecting the battery because it will drain enough power to lower the battery to 9volts so not enough for the car to start. I have a .750 milliamp drain in the system.

What could it be? I head of a relay under the sterring but it is really confusing for me as i don't know these models so well.

Thank you for your help guys!

Well, you've narrowed it down to a relay. What circuits are related to that relay? How did you narrow it down to this?

I thought i had narrowed the trouble. I found that the drain was on my MPX-B fuse. I removed it and ran the car like this a moment. 2 weeks later, after leaving the car sit in the parking for 2 days. I decided to take it for a ride and boom, no power at all, nada. So I removed the battery and heard a relay clicking one time. Since that happened, i never took the car.

On top of this, i wanted to jumpstart the car and reversed the cables so i blew a bunch of fuses. Still have no radio/clock/door lock and dome light, but i didn't checked yet the passenger side fuse box. I assume that the Dome fuse is dead too. The car runs fine and i have no check engine.
