Ok, I set my multimeter to 200 in the DCV section. I held the probes on the red and black wires on the back of the motor. To simulate a payout, I put my machine into credit mode. Then I added a bunch of coins. With the probes held onto the two wires, I had someone hold down that credit mode button. The hopper then pays out all the credits that are on the machine. The multimeter stayed at 0 the entire time. Which port should the red wire be plugged into on my multimeter? Theres a 10ADC (10A Max) hole, and a VΩmA (750VAC/1000VDC/200mAmax) hole. I tried both of them, and the multimeter still read 0 both ways. I just want to know which hole the red wire should be plugged into for what we're doing here.

Also, so I guess it's AC powered then, not DC, if it read 0 right? Unless I messed something up? I just held the probes on the outside of the wire casing, which I'm assuming is what I was supposed to do? So what then if it's AC? Is there a way I can confirm that it is AC with the multimeter?
