Electrical problem after LPG install

[markdswan]

Hi All,

Had a LPG conversion done today, all seems well except...

The Roof doesn't work, the rear switches for the electric blinds don't work (but the front ones do)
the 12v lighting in the conversion doesn't work
rear courtesy lights don't work....

I have checked a few of the fuses and all seems well

I will of course be back in touch with the LPG conversion company on Monday but, I seems to me that maybe a common neutral has been left off somewhere in the back which is affecting all these systems, are there any easy positions I can check?

Start by checking the handbrake switch is working and brings the dashboard brake light on, if the light doesn't come on then the Roof won't go up either. To chaeck the switch take the arm rest console off and look at the back of the handbrake a very simple switch set-up which often needs cleaning tweaking.
As regards the lights in the rear I think one of the conversions has an extra relay to ensure that all the lights go off when driving - this may also be triggered by the handbrake switch, but might be something else.

Thanks Geoff,

Hand Brake diagnosis was spot on as far as the roof goes!, lights and rear blind switches still no good, a bit dark to keep looking now, so will continue tomorrow

Thanks again.

The Blinds sound strange, the switches in the front handle Near Side and Off Side as pairs, the switches in the rear handle each blind individually, however they all use common wiring, so its a bid odd that the front pair of switches work and all 4 rear ones don't ? One thing that might be common is the front switches seem to rarely get used and can some times get a bit dirty, so it might just be worth operating them a few times and then check the rear switches for operation.
The lights driven from the conversion, are a little more difficult to comment on as they all vary depending on the convertor!
