in amp mode you are shorting the power to ground,
if you want to see the current draw the meter needs to be in amp mode and in series with the blue wire (cut the blue wire and one meter lead goes to both blue ends).
If you want to see the voltage output from the controller just change the meter to DC volts higher then 12.
I am not sure the issue or what you are trying to do so I can't advise on the better approach
Voltage output from the controller.....that tells me if the controller is sending the current out to the 7-pin and beyond, yes? If the lights are working does that mean it's sending out voltage?
I don't know what I want in terms of outputs and draws. That's lingo I don't know. I want to know if the controller is working. Then I want to know if the brakes are getting power, and if they work. I want to know things are working before I got back out on the road, without moving the rig.
