OK here is my weekend's conundrum.Spent last few days wiring in a radio...generally ok but waiting to get a better unit.Went yesterday on a 100 mile round trip in that really heavy rain.That evening headlights didnt work.Have investigated fuse box today and there was some water in it.Dried it out redid one dodgy connection to fuse 7( for rear lights and side lights.)Now the headlamps work but side and rear lights dont go off even with stalk switch in off position and IGNITION OFF!.Horn also doesnt work when in off position but do when headlights are switched on.Thought it was the switch cluster which I changed but still same problem.I cannot think where in that circuit battery-fuse-switch and lights the problem can be.I would appreciate any help on this please.Perhaps some water is still branching across somewhere? matt g
