Hi @ all!

 

Hope someone can help me out!

My supra have following problem!

 

All the time '(no matter if open or closed) the headlight goes on somtimes after 20 minutes then after 2 hours aso...

Its nothing to do with the stork because i also have already disconected the stork!

Also the relay i have changed in the engine bay (Headlight relay)

I took my voltmeter and have a look when it comes on!

Sometimes i have 0 voltage then it goes up to 7 , 8, 12 (between 9 and 12) the lamps in the headlight begin to burn!

You also hear the power going throu the relay!

 

What kind of problem could this be!?

I am complete confused about this!

I also throu out everything non original like the alarm aso....

 

Hope someone can help me out!

At the moment i take out the 15Amp fuse for the right and left headlight!

So it can not begin to burn!

 

Thanks for all helps

 

Roman

Just trace the wires from the relay/fuse box all the way up to wathever it goes, on your way you definitly will find the fault. Maybe someone messed up the wiring before. Don't know for sure if supra's have a headlight control module, if so it could be something with the circuit board.
