Im looking at a Jato for a mate of mine that wont start, and normally i can fix most things to do with R/c cars. The problem starts with the Ez Start system, on the cars last outing the glow plug died so it was duly changed and it started first time, later it had a bit of a knock and it broke a lower arm. Since trying to start for the next outing the glow plug light fails to light on the Ez start wand. Ive tried everything to my knowledge, ive changed wiring looms, checked the earth on the motor mount, tried a different glow plug and wand, checked the resistances of the wiring and connection of the pins in the plug! Still no glow plug light! The motor cranks over, fails to start and the light lights up but no glow plug circuit. Any ideas???

Im stumped!!
