Temp gauge resistors so I can test the gauge HX HZ

Just checking that you've got the guage cluster bolted in the dash frame, as one of the bolt holes has an earth connection. It might not work properly if not bolted in.

thanks Max, yes it is the other 3 gauges work ok
I am still scratching my head as the cluster was given the once over by a very reputable guy here in Perth
