Testing electric brakes, Update.
I want to test out the electrical side of our fivers brakes. I read an article giving the max amp draw for four 10 or 12 inch brakes as 11.3 - 13.3. I can use a 20 amp multi tester. My thinking is to...

Prodigy P3 controller, not giving any errors. I could get some slowing from the trailer brakes when I pulled the manual lever, but nowhere near enough. This was after brake adjustments.
I suspect poor wire connections, but don’t want to break them open without testing what I can.
Extra work to go wheel to wheel to find the culprit. Clamp-on meter will identify the issue without cut and repair.
When I had drums I did find it took a few stops before full braking power was obtained. OK maybe 10 to 20 stops. So get on some open road for a bit before you call them bad.
BTW P3 works great with disk brakes :)
