I've had battery problems with my XE Nova for a few months and have now (kind of) found the problem.
If you put a multimeter across the battery when its running it shows 14+ volts, that's fine.
When you turn the car off and leave the meter on the battery, it loses charge at a substantial rate until it's completely dead.
Finally found the problem to be the main feed that goes into the car, behind the dash and splits off into 5/6, thinner red wires.
I've tried pulling each fuse out 1 by 1 to no avail, the charge still drops.
So next of the list is to remove the dash and find out what these red wires go to.
Has anybody had this problem before or know what this thick red wire splits off into?
Many thanks.
