Wiring issue??

supraturbo_mk3 · 08-16-2011, 07:34 PM

Stupid question....I'm good with the engine but the wiring, I wouldn't know where to start So I'm looking for suggestions on how to diagnose this problem.

My blinkers stopped working all of them no ticking sound at all.

Dash lights went out, temp gauge and fuel gauge stopped working.

I checked all the fuses, they are all good

The only fuse which will kill MOST of the cluster is the 7.5A Dash fuse. The cluster and the blinkers share NO wiring except for one minor thing; The interior signal indicators (the arrow lights) share a ground with the cluster (On the steering column or the floorboard, can't recall which). Do note that the signals will not work if the hazard switch is disconnected or defective or if the flasher relay is bad.

Yes I discovered by accident ( as many people do ) that with the hazard plug d/c your turn signals won't activate. Be sure to use Hand signals while diving.
