I've been playing with the interior light in the Gransport.
The buttons didn't work, so one culprit was a failed reading light bulb (I have no spare) but the 'normal' interior light doesn't work on the switch.
I dropped the whole unti out, and figured out the connections (I think - does the unit run permanent live and switch to Earth, ot the other way around?) and then put a meter across the switch terminals and tested the switches and neither did anything.
I'm assuming that this is a proper switch, not some CAN bus connected signal generator, so it looks like neither switch operates.
Looking from ABOVE the unit I think the terminals are as follows, left to right..
for a switched live system
L - this confuses me - it looks like a switched neutral for the tiny Switch illumination lamp which comes on when exterior lights are on
2 - Perm live - feeds the 2 switches and the tiny switch light lamp.
3 - Door open Switched live for interior light
4 - Neutral return for the 2 bulbs
Am I best just spending £20 on a secondhand unit?
Thanks
Paul
