I know there's continuity, but how would I know if it reads current/flow when it's not installed yet?
As always, thanks.

DO NOT TRY TO START THE VEHICLE! It's OK to turn the ignition switch to the "accessory" or "ignition on" position. Turn on any accessories you can, such as high beam headlights, wipers, heater blower, cigarette lighter, etc. Depending on how it's connected, the ammeter will indicate either "charge" or "discharge". Reverse the leads at the ammeter, turn on the load again, and see if the needle swings the other way.
