i am still investigating the fault, yesterday i rewired from termination block to termination block for the headlights and part of the loom going back to the switch, the cable going down to the dimmer is a bit of a mess but it is still intact with no copper showing. i am getting 11v at the termination blocks for the headlights when the switch is pulled out but not at all points. it looks like the previous owner installed a new switch, it looks new.
i am not sure when the fuse blows i need to look at that. the guy who had it before me has installed an assesory home made type of fuse block maybe thats causing the problem.
because it has had a V8 installed it has aftermarket temp and amp gauges, the amp gauge used to show normal (13v to 14v) but recently it is showing low in the red, when i apply the turn signal the amp needle moves up and down slightly as the bulb flashes on and off. its driving me nuts!
