This can be done, but it is a tricky operation, because the amp draw is such a short duration, you may not get an accurate visual reading using a conventional amp meter. You will need one that holds peak current draw. To get a true reading you would need to get as close to the actuator as possible, but tapping in line will be a pain, You will get a fair indication if you connect an amp meter between the battery Pos(+) and the battery cable, operate the lock and watch for peak current draw, if one spikes higher, there is a starting point, but a meter which holds peak drain memory will be a great advantage.
