Some advice please. RRC 1986 Vogue
Offside dip was working ok then stopped so I investigated expecting a duff bulb.
Replaced fuse and all worked well for a few minutes then the radio was drowned by interferece ( engine off ).. After about 30sec the fuse popped and the radio was perfect again. This was repeated in exactly the same way.
According to some circuit diagrams the headlight wash/wipe is on this fuse. Although I do not have this there is some wiring in the vicinity of the offside headlight which could be for that. I checked and all seems insulated.
Can anyone explain the interference and the delay in blowing the fuse. Engine is off so there is no vibration throwing cables about.
Any ideas appreciated.
