Having solved he previous lighting problem by replacing the rear offside light cluster....a new gremlin emerged today.
Basically, my Trak now has a life of its own.....it switched its sidelights on itself this afternoon!! When I went out to check, thinking I had probably left them on, I found the on the stalk the lights were switched off. Having seen this, I am also very happy that I had switched the lights off in the first place as it was still dark when I got to work.
Anyone heard of this before? Any obvious candidates for the fault?
