Battery drain

[patnben]

I had a similar problem with my old Bomgo a couple of years ago
and the batteries were fairly new and no excessive current drain.

I traced it to the central locking system, the rear lock had siezed
and hadn't closed completely and remained energised all night. In
the morning I had an almost flat battery. I freed it up with silicon
grease and it's worked OK ever since. It was difficult to find as I
was looking for it with the doors unlocked and it must have gone
to the unlocked position as normal !!!.
