[Mgs] B/GT electrical problems

[John DiFede]

Sarah. The voltage stabilizer sends reduced voltage to the fuel and temp gauges.  The temp gauge going up to H may be a wiring problem.  If the wire to the temp sending unit is grounded that could cause the gauge to read H. 
 The tach not working may be a different problem.

I have a vague memory of having a stabilizer fail years ago, and some of the gauges not working thereafter, but I don’t remember which ones it was.  Wisdom of the List?
