It cant be a fused line given that you still get
the battery flattened with no fuses installed.

If you can somehow rig up something that allows you to
see or hear the current draw, or have someone else watch
the meter, you may be able to see if its a door by doing
that and operating the doors.

I've only ever seen it by leaving a multimeter connected with a maximum
function running. Car sat perfectly still, it just does it sometimes
overnight.

Yeah, you really need a proper data logger. Not expensive.


Not spending money on stuff for one little purpose like that.


But you did with the charger to kludge around the fault.


A 13.8V 15A power supply is very useful for all sorts.

And you should be able to flog it for about what you paid
for it once it has fixed the problem.


Too much hassle and I lose postage and Ebay fees etc. Only time I've bothered "renting" something like that was a top of the range slide scanner for a large amount of 35mm slides I wanted digitised.

And I can't see it would tell me anything, apart from "it happened at
5am".


When it happens and the detail of how it happens
may well allow you to work out what is causing the
flattening of the battery overnight and fix the problem.


What can it tell me apart from the time of night it did it?

And that would allow you to see which door is the problem
too if it is one of the doors pinching a cable as its closed.


What makes you think it's a door?


Its the most obvious way to pinch a cable.


Actually I've just had an ABS wire fixed that had been damaged by the handbrake.

It happens randomly overnight when nothing has been moved.


But the change in the metal around the door may well
happen as the ambient temperature changes overnight.


I won't know which door from the reading from the data logger.
