| Urghhhh .... Yesterday I reported that it was all working with the tail light innards hanging out, and I (wrongly) assumed that the problem was inside the tail light. I have reassembled it all this morning with tape around the connections inside the housing ... and found that when back on the bike it still blew the 10A fuse when you operate the stop light with the engine running.
I think I have now solved the problem though.
A few more blown fuses and I am pretty sure it is the wires where they come out of the metal tube under the exhaust. The fuse only blows when I do up the 2 back screws tight. Whilst I cannot actually see a break in the insulation where the wires go into the plug, I have wrapped gaffer tape around the exposed wires and pushed it back into the tube. Now when I tighten the screws on the light unit and test it does not blow.
Tonight will be the "acid test" because I am doing a 50 miles round trip.
Picture of how the wires look where they come out of the tube. The light unit screws up on either side at this point so I think it was pressing the wires against the sharp edge of the tube.  |
