Does any one know how the water temp light works on my 1971 HC Deluxe Viva? Also I"ve
just sorted all the warning lights to operate correctly on this model (except the water temp light)when I switch either indicator on and if any other warning lights are working at the same time as the indicator all the lit warning lights flash slightly along with the indicator light! Does anyone out there why this happens, thanx, vivapeteSLNO3.
