Shug Posted August 21, 2010 Share Posted August 21, 2010 This is now officially doing my head in! Used a universal wiring loom on my A series as the original was toast, and I'll be damned if I can get the headlights working. I have the switch, relay and headlights all wired in. Sidelights work perfectly, headlights don't. In a nutshell, I have the headlight switch wired to the relay, with switched live wires. When the switch is on, power goes to the relay on the wire from switch. With ignition on, power goes to the other side of the relay. This should close the relay, sending power from the other switched live to the headlights and lighting them up. Except nothing happens. If I bypass the relay and wire lights straight to either the headlight switch wire, or the switched live (the wire the relay should connect it to), they come on. My meter shows the connection being made between the switched live and headlight wire when both switch and ignition are on, but the headlights don't come on. Given the meter shows the connection apparently being made, surely that means the relay is ok? (I've tried 3, all new) Engine turns over on ignition and fuel pump, which runs off switched live as well, runs. If it wasn't obvious before, I'll mention I have zero prior experience in car electrics! As if that wasn't obscure enough, my hazards lights work, but indicators don't...
