Can anyone help. Working on my 2wd saph today and all was well until i was about to lock it up and notice the dash display wasnt working, no rev counter no ignition lights, no temp reading, no petrol tank reading nothing. The main light behind the dash was working though. Then i noticed the water starting to boil in the header tank because the fan never came on and water bubbled out all over the place, i only recently changed the thermostat as exactly the same thing was happining.
Can anybody help?
