Finally replaced the brushes in my pump and thoroughly skinned my knuckles refitting it. Still no joy with it firing up,akways has been intermittant Thought id give the bus a treat and wash it Pulked out of the wash and there it was burning away merrily. Then i remembered this has happened before,same carwash tho on the way to work Seems to suggest a wiring fault but where do you guys reckon it could be? Front scuttle nr the temp sensor or underneath around the burner itself? That seems unlikely to me due to it location high up underneath Or should i just move closer to that wash:-)
