Interior lights blowing fuses

[Bill D]

Interior lights blowing and sidelights. Fuse blow when fitting with lights off so must be to do with interior lights. Any suggestions would be great

Is this on a standard build or has it had any conversion/ additions made to it which may be connected to that circuit.

 

[Bill D]

on a conversion I don't know what else is connected to it but everything else seems to be working. Worked ok for a few weeks. I put a bulb across fuse and the bulb lights but flickers with ignition and everything off. Fit a fuse and blows straight away.

Is it just standard interior lights or are your rear lights connected ? I would remove the bulbs and fit new fuse then if fuse is still ok fit the bulbs one by one to narrow your search down circuit wise

I will try anything but fuse blows with no lights on. Interior lights in cab are standard all lights in rear are from control board. I still believe it interior cab light wiring or lamp is at fault

 

[Niknak]

Strange sounds like you have a direct short, have you had anything else added or altered in the cab lately

 

[Bill D]

Does the bcm control the interior lights on T6

 

[rover220]

Yes

 

[Bill D]

Yes

Where is the BCM and do you have wiring diagram for interior lights. I have a dead short on interior light

 

[Niknak]

Have you had a windscreen lately

 

[Niknak]

I’m sure bcm is located around right knee level as you sit in the drivers seat

 

[Bill D]

Have you had a windscreen lately

No but conversion was done 2 months ago. Getting a metal to metal cracking sound from dashboard area. Could have something to do with it

 

[Niknak]

That does not sound good

 

[Bill D]

That does not sound good

How much work is it to remove dashboard
If I had an idea where loom runs maybe could get away with out removing dash. I take it interior wiring runs up n/s of screen

 

[Niknak]

I’ve not looked tbh sorry can’t help

 

[Bill D]

I’ve not looked tbh sorry can’t help

Ok thanks

There is a brown muti plug n/s behind glove box. I disconected it and fuse stopped blowing and side lights working. The loom to this plug comes from interior lights. The interior light witch is held on by 2 screws unlike the T5 is linked somehow to this plug but light works by buttons on it. I think the plug must feed switches or doors. Any ideas or wiring for interior light out there. Fault was no interior lights and no sidelights.
