Hi Phil,
I have tried all combinations of locking/unlocking etc and whatever I do the drain is always about 22ma. I have now taken volt readings when cold which is about 14.02v and when warm about 13.9. As per previous suggestions I have now disconnected the alarm sounder and will replace the pos battery terminal in the morning but I have carefully inspected both terminals and can see no faults. I have also now turned off the day running lights. I will then let the customer have it back and see what happens.
Many thanks for all the suggestions.
Bryan.
