Hi all,
took my bus for a run today (1.9 td 1989) ran for about 60 mile then temp light started flashing ,stopped checked aux water tank it was full, in fact too much water some poured out,bit strange was at right level before.Temp gauge needle never went past midway (FAN NEVER CAME ON ONCE )But light still flashing,
all heaters working fine,water wasn't even hot in tank.
tried to check main water tank but plastic that old can hardly see if its full.
So not sure could it be faulty switch ,wire, or sender etc.any thoughts .How can I check wiring ???
thanks
