Someone can help me. I have a S 10 2.8 TD, I had short preheater and jumped the fuse, repaired that, now I see that the signal of (-) does not reach the relay of the preal.
You can tell me if the timer is an independent module and where it goes, or if it is the ECU that manages time.
Any orientation and help will be well received.
Cordial hug everyone.
