On the back of the Glow Plug/Alarm Test toggle switch are 6 terminals (in 3 pairs) but only 4 wires. Is anyone able to tell me which terminals are left free please? Top pair, middle pair or bottom pair?
No - got the manual. Got the wiring diagram. In fact I have two of them but they don't help. The toggle has six terminals but four wires - ok two of them are paired onto the same spade but there is only four connections for six terminals. So like I said 'anyone know which afre left free?' The wiring diagram suggest the terminals are numbered - well perhaps they are but I can't see any numbers.
