I'm sure it's on DC, and I've measured with the pos at the solenoid where it outputs to the starter, neg grounded, and with the pos at the starter (replaced the solenoid to starter wire, so I wanted to make sure it wasn't that).

I'll check grounding tonight to be sure, tho I did do some various jumpering at one point to try to eliminate stuff like that. I think I did neg battery terminal to engine block, but not sure.
