Check main fuse (there are only two fuses and a spare in the fuse block) one fuse is marked MAIN and the other is Accessory - both are 15 amp - from the fuse block, power goes to the key switch via a red wire with a black stripe (here's the confusing part) there are 3 r/b wires at the key switch connector - the single one is 12v in - when the switch is 'ON', the other two r/b wires have power - both r/b wires that are hot when the key is on go to the LH handlebar switch. Check for 12v on the r/b wires at the handlebar switch - if you have 12v at the switch, with the switch in the 'RUN' position, you should then have 12v on the red wire with the white stripe - with 12v on the r/w wire, the lights should work. If the lights work, then most like all else will work also. Let me know the outcome.
