Well, thanks for the advice above, I too suspected the old radio as causing some form of issue with the electrics. I found the fuse for the central locking, that was separate to the fuse we had blow on us numerous times before, but had still blown this time.


I removed the old radio today and found some things worked when they never did before, I didn't realise there was actually an acc with the van, having the key at off but still in the ignition, up until today the radio and other electrics were either on or off with the engine. With the radio removed there was other bits working where the didn't before like the interior lights and the trip functions and such.

I suspect there was some form of partial short in the radio that prevented the electrics from working the way they should.

I have replaced the problem fuse with another one, but a lower amp so I can be sure that replacing the radio has resolved the issue and also to provide better protection for the electrics with another possible short.

I also found the wire that burned through it's insulation, once I get time I will link it here as it appeared to be completely disconnected from anything, just connected to an orange/brown round thing next to the fuse box, I would like to know what that is and whether or not removing this wire from there will have any affect.

It looks like the previous radio was quite poorly installed, they made quite a mess of the wiring harness and as such I had little slack to work with. I fitted it all however, so it remains to be seen as to whether or not the fuse will blow again.

Can anyone suggest, while I have the trim off, what I should expect from the outputs and such of the cruise control stalk so I can begin to work out where the issue with that is hiding?
