So the saga continues but I think I'm much closer. Turns out I do have white / white and black / black connectors so no confusion possible there. Al (ssjones) and Benny had said about getting the connects switched around but it seems Triumph must have changed that - maybe on the '06. Switched them anyway to check and nothing works so definitely rules that out.

Previously I said I thought I may have mixed up wires 'cos the bike wouldn't start AND the headlight wasn't working. Scratch that - nothing wrong with the starter. I hadn't connected my throttle cables up in my haste to check out the wring...not knowing that with throttle cables disconnected - bike won't start. Appears that is the case. Who’d have thunk it ???

So the only problem I ever actually had was the headlight. No headlight and I blow the hi/lo fuse every time I turn on the ignition. So I check my wiring against what I wrote down - nothing obvious there, all appears correct. Get my multi-meter out. Not exactly sure what I’m doing with it but tested resistance (ohms) between each wire at the hi/lo headlight switch (blue/yellow, red/black, red/yellow) to the corresponding pin in the connector don in the headlight bucket. I get the signal telling me I have resistance so I assume all the wires are connected as they should be. Was that the right thing to do ? Phil mentioned "ohm them to ground" - not sure what you mean ?

My assumption is therefore, I must have a short in one of the wires somewhere, bit of wire exposed somewhere in the join up in the bars, but before I cut and pull the whole bundle out to check I thought I’d ask for any ideas or help one last time.

Any thoughts guys ????
