Ram integrated brake control
So we have our new 2016 3500 Ram Turbo diesel and we are wondering how many other Ram owners are having this issue. We picked up our trailer the other day and when using the brakes it feels as i...

If a brake controller is not capable of producing 12vdc (as read by any standard VM) and/or 3a (at each brake, as read by any decent clamp-on ammeter), then it is not performing up to the generally accepted industry standard.
Me Again, curious, can you explain why the voltage and current readings on my 2016 Ram IBC increase at the same proportional rate until reaching the following maximum values? V = I x R.
2016 Ram IBC:
~8 vdc, 66% of 12 vdc.
~2 amps, 66% of 3 amps.
Here are the maximum voltage/current readings I observed after disconnecting the Ram IBC and installing a Tekonsha P3 on the same 2016 Ram truck (connected to the same trailer):
~12 vdc, 100% of 12vdc.
~3 amps, 100% of 3 amps.
Thanks!
When you took those measurements, was the truck moving at highway speeds? I'm pretty sure the RAM and others reduce the controller output at low speeds. But the P3 does not.
Have read on another forum that it was at low speeds, around town, that people were having the problems with the RAM controller. I got the impression that RAM was being too aggressive in cutting down the output at low speeds.
