Wiring gremlin I think!!! Help needed

[JD_RS172]

So I recently did a ph2 dash conversion in my ph1. Everything is wired up fine and working correctly at the expense of the skin on my fingers!

Thing is. My clock/temperature unit isn't illuminated. It works but isn't illuminated. I've checked all the fuses, changed the bulbs and checked the dimmer switch multiple times. Stripped the dash back down to check all the wiring and I think it's beaten me!

Is there anything I'm overlooking here?

Thanks

I'd check the bulbs unless it's the later 182 type unit which has SMD LED's on the PCB. It should illuminate at key/radio on regardless and then the intensity dips when the lighting circuit is active (and then becomes controlled by the interior level resistor)

Thanks for the reply mick.

Yeah I put two new bulbs in. They aren't the LED type so I had a few spare. Yeah this is what I thought. The unit has power because it works perfectly it just doesn't illuminate.

Everything else works perfectly on the dash it's just this!

Have you checked the PCB tracks to see if they have voltage/earth when turned on?

Ah no I haven't. I'll give that a shot.
