Reverse light failure

[mordred1973]

So the bulb failure warning went and told me left reverse bulb had failed, having taken light cluster out, changed bulb (which looked ok) put it all back, you guessed it, it still doesn't work and the warning is correctly still showing.

The right hand reverse light is working fine.

Anyone got an ideas? the bulb holder looks ok, it's the one bulb of the lot that just pushes in.....

Cheers and Happy New Year guys and gals

First check on the Rear Lamp Unit flat 7 way connector that the Black with Blue stripe wire has 12 volts on the car's connection when the car is in reverse.

- If yes, the fault is in the Rear Lamp Unit metal track to the lamp holder from the Rear Lamp Unit connection. Line out with a DVM to narrow where in the unit it is failing to work releative to the car connection point.

- If not, most likely a fault within the Central Electrics 09 Controller just below the cubby holder draw by the headlight switch, inside the dash. The Black/Blue wire is straight from the rear connection to the Controller 09 connection. The split for left/right reversing lights is inside the CE-09 controller so the reverse switch and its single wire feed input to the Controller 09 are OK.

Assume the other lights work like sidelights in the Rear Lamp Unit, in which case the earth Brown wire is OK. The earth "star " connection onto the metal bodywork is behind the small access panel removed to get at the securing wingnut for the Rear Lamp Unit. The Star has two earth Brown wires attached to it.
