Where is the alternator fuse in a Lexus gs 400

SOURCE: 1993 Lexus GS 300 won't start. Alternator fine,

fuel pump could be out

SOURCE: Fuse Box ( cover) diagram for a 95 Lexus LS 400 is missing.

check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.

Testimonial: "Thank you! You was right, it was not the alternator, it was a 125 AMP that was blown."

start by checking fuses are there any warning lights on,some of these systems pick up the speed reading from the abs

Your throttle position sensor might be stuck on the wide open throttle setting!

Do you have any check engine codes? Is the check engine light on?

It might not be if the TPS is still in the normal range...but is just sticking open.
