Thank you. I hate electrics now. They just keep going wrong even though it had a re wire about 6 years ago.
Nothing like replying late. But haven't been on for a while for one reason or another. I cleaned all connections and replaced fuses and seemed to be working until recently. Now they have stopped working again. Checked switch and that appears to be working well. Going to run more tests on the earth and feeds to the light units themselves. Failing that I'm a bit stuck. Is it likely something inside the servo is causing the problem?? Even though my brakes work well and haven't changed performance wise for the last year or so since the repairs were carried out to some springs within the brake drums.
