Replacing the wiring loom with a single diode connection electric ignition loom from L.P.Williams, we have all the lights working except for the indicators and indicator console light. The wiring is connected as shown in my original hand book, with all Headlight wires matching on new and old loom when placed side by side before fitting, except for a red and white wire which we discovered was for the electric start model. We have tried many assorted wiring combinations in the head lamp without success. Can any one "shed light"! on where we are going wrong! the old wiring loom is an original fitting from the Triumph factory.
If you haven't found the fix.....No flashers, Check you grounding. Before you spend a fortune on parts, put a screw driver between the headlamp bracket and the forks. I had the same problem after a new harness was put on and found the fix by accident when I touched the bracket to the frame with a jump wire. The Fix: a wire between the inside nut of the flasher arm on the bracket and the bolt holding the bracket to the forks. Ground, or as you Brits put it Earth....
