Not many multimeters are able to measure 1-20 amps of current.
multimeters measure miliamps. a good meter would trip a breaker or
blow a fuse where a cheap multimeter will let the smoke out if you
apply even 1 amp.
An old fashioned car ammeter could do it, but you'd have to wire in inline.
So a multimeter won't work?

Either an ammeter between the disconnected ground strap and the

At low draw, the ammeter between ground strap and negative post is
more accurate.
