I was driving my friends 535 last night and I noticed that the temp guage pegs hot as soon as the ignition switch is it turned to the run position, tells me it is grounding somewhere. I could not find the wiring diagram in the Bentley manual for this circuit. The problem started after he had it serviced and the repair shop reset the SI lights. The shop voluntered that the guage started doing this after they reset the lights yet they could find nothing wrong. I was wondering if anyone has had this happen to them and if I can get a wiring diagram for the temp guage.
