What should the current draw be with a car parked, for the night, not
running, Volvo v40 with factory alarm but never activated. How do you
check this. In the morning my battery is low. Can I use a 120v digital
clamp on amp meter.


I use the amp meter on a digital car multimeter. Normally, when not
running and key off, a car pulls just enough current to keep the
computer and the digital stereo settings alive, which isn't much. I
don't know exactly how much but I would bet it's way below a half an amp.

In any case, to track down a current leak, attach an amp meter and start
pulling fuses until you find the one that is pulling excessive current.
