I am seeing a 1.5A DC drain on my Amp-Clamp when taking the rubbish out and popping the trunk to check. My boot lights are LED so it is not them..
The meter has a min and max function which I will use to see if it settles down to a lower current some time after the boot is closed.
If the weather was better, I would just flick the catch to make it think the boot's closed and keep checking it.
I suppose I could also do a video call from another mobile phone and leave the line open to keep checking.
For anyone who wants one, I recommend one that doesn't auto power off too soon - mine is 30mins.
Interesting theory about the diode for the alternator.
