Your meter isn't reading "current" flowing through the speed controller
in that arrangement, it is reading "voltage" across the speed controller
(in the reverse direction). In other words, the controller is
completing an electrical circuit between the "top" battery and the meter
because of the way you have things wired, but it probably won't pass
much current. Most likely, you're reading reverse voltage across the
FETs used in the speed controller.

I am wiring up my turret and I have run into what I think is a
problem. I am unsure if it's a major problem or not but I think my
Scorpion Mini speed controller for the turret rotate is letting
current back through it. I have attached a wiring diagram (be easy on
it, I'm not an artist). Should my multimeter be picking up current
with the switch off and if so, is there a problem with it?
Thanks,
Tom
