im not sure ive only used a simple test light, it gets pretty bright. like its getting 12 volts, but im not 100% sure really.

you could take a wire from the pos terminal off the battery, then touch it to the little stud and see if it cranks.

bridging the two studs with a screw driver does the same thing tho. the pos cable should have 12 volts. that might be worth checking with your vm.
