One head light goes out when main beam is on

Check to see if you have power at the fuse connector, that will tell you if it is the switch side or the light side, the switch only has one output but feeds two fuses. As one side works that would indicate the switch is ok and as low beam works the earth must be ok.
I’ll have a look tomorrow, 5 hours of buggering about. Time for an adult beverage. Thanks for everyone’s help today.
 
Well to draw an end to this, after 2 days of messing around trying to find faults this morning I switched the ignition on, put the headlights on then main beam and all worked? Haven’t altered anything?
 
Well bit of an update, I’d left the headlights unplugged. Checked with the voltmeter to see if there was still power on main beam and yes power was still there. Plugged the headlight in and checked to see if it worked and it did. Tried to unplug the headlight and of the 3 pins, 2 were easily coming out of the plug and 1 wouldn’t move. The main beam spade fitting was truely stuck in. Basically had to wiggle the crap out of it to get it out. looked inside and it had fell to bits. So replaced it with a new h4 plug and you never know......
