Blown fuse (1 Viewer)

[GrannieAnnie]

Has anyone got a wiring diagram for a Chasson Flash 20 2014? We have a blown fuse 20amp for the lighting and I presume 12v sockets (as they do not work) I have replaced the fuse but it just blew again straight away. The lighting to the rear of the van above the bed and the bathroom works. Any ideas how to trace the fault appreciated thanks

Any good?

Just a quick google search so may be the wrong loom.

Don't replace the fuse until the fault is found.

Start with the lights , remove all lamps..
Unplug anything that is pugged into the 12v sockets
Now try fitting a new fuse..

Does it blow or not ... if not then replace the lamps one at a time and see if they work
you may find one lamp causes the fuse to blow..

If the refuse blows, then there may be a short in the wiring at one of the lights or sockets ..

It's just a matter of methodical elimination.. you may get lucky and find the fault quickly.. or it may be the last lamp or socket you check

When looking at the wiring behind the laps or sockets, a short will normally be obvious .. insulation burned and Pos and Neg wires fused together..

When you find the cause, cut off the burned ends and remake.. put fuse back and celebrate ..

To stop wasting fuses as you test you could put a continuity test between the fuse “outlet” side ( to the lamp circuit) and earth. When you insert a bulb and get continuity, that is the fault bulb. If you get continuity without inserting bulbs then it’s the wiring and further strip down of the light fittings and then wiring will be needed.

Thanks everyone sorted now. It was the 12v socket for the tv the connector had been dislodged behind and was touching. Vans in pieces now but we found it phew!
