I have a 2003 Lexus GS300. Came home and it won't turn over no dash lights nothing, I charged the battery and still nothing, I found I had an ALT 120A fuse blowed, I put a new one in and everything comes on now accept my Radio and it still won't turn over no clicking or anything, I changed the starter relay and nothing checked starter fuse and it's good. I tried useing the flat key and card to reset the the security system and still nothing. I'm lost. Need help anyone else have this happen

 

Have you tried jumping the starter solenoid with the key in ignition? I suppose first, check for power at the starter with a meter. If theres no power, theres probably another blown fuse (I cant remember the schematics sorry ) if there is power, could be a starter issue. At this point, try jumping the solenoid. If that does nothing, then have someone turn the key while you bang the starter to see if it engages.

 

Yep bang the starter. That's how you really know it's bad.

 

If YOUR 120AMP FUSE WAS BLOWN THEN YOU MAY HAVE OTHER FUSES BLOWN TOO. GET A TESTER LIGHT AND CHECK EACH AND EVERY FUSE. BY THE WAY A 120 AMP FUSE DONT JUST BLOW LIKE THAT. EITHER YOU TRY TO JUMP START BY CONNECTING YOUR CABLES REVERSE.

 

I have banged on the starter a little but I will try that again and check the fuses
