Leyland Car Owners - Not always the electrical switch

The problem may not be the switch itself.
: The switch in my car stopped functioning at all.
: I couldn't start it.
: With the help of a friend (an auto electrician in a former life) we got it to start, and it would restart
: while the engine was warm.
: But it would not start next morning when it was cold!

: I changed the inhibitor switch on the gear box, no improvement.
: I changed the ignition switch, using a new 'foreign' switch. No improvement.
: I changed the relay, no improvement.

: I was stumped for a while, but I dare not use the car because I knew I would get caught.
: There was nothing else wrong with the car.
: Then I had another idea.
: The inhibitor switch wiring loom was 30 years old and had suffered heat over the years.
: All the original connectors were still in use.
: New connectors didn't help either.
: Then, I replaced one of the white/red flash wires in the inhibitor switch wiring loom, and full improvement!!

: I rebuilt the whole inhibitor switch wiring loom, and fitted it, and with the new ignition switch, it started like a new car, and has done ever since.

: Before blaming your switch which is difficult to replace, check the inhibitor switch wiring loom; don't assume that the old wiring is as good as it was when new.
