I had this EXACT issue on my is300 i replaced the relay and now my car starts but my dash wont light up at all and i checked all fuzes any ideas you can help me? Tyia
@@John_does_is300 i actually fixed the issue it was one of the prongs of the fuse stuck in its spot pulled it out and got a new 120 amp and everything worls now!!
Damn bro it looks like u know more then me i have a 01 lexus is300 it cranks and has power but doesnt seem to turn on my engine does over heat and shi so do you think its a blown head gasket?
So I’m having pretty much the exact same problem car had power ran I turned it off went to start it again and no power at all I changed the 120 amp alternator fuse chased wires cannot seem to find the problem new battery everything I can think electrical wise I’m going to try this tomorrow to see if I have any luck I do have a question when you lose power do you lose power to everything including the windows lights because I lost power to everything
@@John_does_is300for the 120A Relay for the Alternator. I’m searching it by name and it’s just giving random universal relays for all sorts of other systems like Fog lights, Fans, etc. nothing that specifically states it’s for the alternator. Or does it even matter?
Ended up changing all electrical Starter, alternator ,ignition switch fuel pump, fuel filter, ground cable from negative battery terminal to engine block and and alternator ground cable to positive terminal and replace battery terminal posts then that didn't work I replaced my fuse box bc the cable had a short and wouldn't hold a connection
It turned out it was a short with the ground for the alternator fuse you gotta make sure the small bolts for the alternator fuse are tight or they will come loose and it'll mess everything up and I replaced the ground from alternator to fuse box
@cameron-co7vq I pretty much made a list of all electrical parts and components and checked them off if it didn't work or didn't fix and the fuse box was last on the list only bc I never checked it but it was one of the cables the wires were corroded
“Nobody even helped me I did it on my own “ idk how much more I can feel those words with this 03 gs300 I just got

Over heating engine can be alot of things could be a radiator thermostat headgasket not enough coolant check those and you may be able to fix it

I fixed my issue it was the positive battery terminal my fuse box and my ground wire from alternator to fuse box
But yes I lost power to everything nothing turned on in the car

Bruh my gs300 died while driving, and hasn’t started since!! It’s been like 2 years… I’m sick. What was the fix?? Or issue please lmk

@@John_does_is300 so the fuse box under the hood is the one you switched?
Yes the one under the hood I just picked one up at the junkyard and it worked fine just make sure you check relays and fuses when you install
Did you found out what problem was I’m having the same issue now
It turned out it was a short with the ground for the alternator fuse you gotta make sure the small bolts for the alternator fuse are tight or they will come loose and it'll mess everything up and I replaced the ground from alternator to fuse box
Is the alt fuse blown?
Turned out it was the fuse box
@@John_does_is300 how’d you find out the whole box was blown?
