I have an issue with my low beam.
It is permanently off.

I have done some fault finding on all the usual

Starter - correctly switching relay
Relay - 12v switching and available at output
Fuse - checked as good

12v measured at fuse (both sides)
12v measured at relay solenoid (12v one side, 0v other)
12v measured at relay switch (12v both sides when solenoid active, 12v one side 0v other when solenoid off)
Measured continuity from bulb return to chassis = 0 ohms
Measured 0v at bulb black/white wire

So my conclusion is a wiring issue from relay to bulbs....

Is there any other connector/component between the relay and bulbs?
Does anyone know how the loom is routed?

If anyone as a wiring schematic, that would also help


Oh, and yes I have checked the bulbs :-)
