there is no voltage at the glow plugs, but there is 12v at the relay, i have checked the cables there are no broken cables any were. what could be the problem?
Hi Simon, first off whats the vehicle?? if theres 12v at the relay is the relay, a)being energised? b)is the coil of the relay ok? can you do a continuity check from the glow plugs back to the relay?
