With your help we can keep all his cars on the road and the smile on his face so please come in and see if you can help.

THESE ARE COMMON AND GENUINE PROBLEMS WITH REAL ANSWERS - WELL WORTH A READ

take a new power lead to the heater and see if it powers up, seems no continuity on the main power line to the heater.

can only think loose connection in the plug which plugs into the heater unit, it supplies the power. check for loose connections there, did think of soldered connections at the switch end but you say he checked them and were ok presumably on the bench?
