If there is no current reading when the meter probe is plugged into the 10A jack, most likely there is a blown 10A fuse inside the meter (probably inside the battery case for easy access).
You also probably need to manually set the meter to the 10A range instead of depending on autoranging.
That comes later, when he forgets to put the test lead back in the V jack and tries to measure the battery voltage (speaking from personal experience).
Haha, speaking from personal experience? That is when the smoke escaped from one of my former VOMs.

I NEVER use the current scale on multi meters. I put some kind of shunt in the circuit, or use
a clamp on meter. No interrupting circuit operation, and no smoke. Bruce Roe
