zig unit problem

[iowcamper]

am currently int he process of changing over my hi top to a pop top, all was going fabulously but today when i was putting back up the unit which holds the zig unit i discovered it is now not working. before i take the unit back down and start playing with wires (not my area of expertise!!) the 2 amp fuse on the front doesnt seem to tighten in to its hole, the fuse is ok but when you pop the fuse into the hole and turn the black pastic cover it doesnt seem to purchase on to anything???? i cant remember what it was like before, the wiring to the back of the zig was left untouched apart from removing the wiring for the light in the old hi top, however i did notice there were a couple of wires behind the zig not connected to anything!!
would the 2 amp fuse not working stop the whole lt from working - i.e mains switch, 12v switch etc
or is it likely i have accidently pulled out a wire when removing the cupboard? hence the 2 wires that dont go anywhere !
obviously i will need to check that i havent screwed through a wire somewhere

any help or advice would be great, if i cannot rectify myself and have to take to an auto electrician any ideas how much they should be charging for finding and rectifying this kind of fault??

You probably have a CF8 unless it has been replaced but check in case it is different. The 20mm 2A fuse is for the 'Mains 240V' protection for the leisure battery charger when on EHU. It should not rotate when attempting to refit the fuse cap so I would check that all is well behind the panel (held by 4 screws). Even with this fuse not inserted your leisure electrical equipment, that runs off the 12V leisure battery supply, should still work as normal. If nothing works then it may be that the Leisure battery is not connected to the ZIG panel. If you have not disturbed the zig unit itself then the chances are that the fault is somewhere else, i.e, the 25A in-line fuse for the leisure elctrical system which is usually located close to the starter battery. If needed, details of the wiring connections at the rear of the ZIG panel can be found in the WIKI.
