So we aren't getting our Scamp Deluxe till late fall, but I've installed a brake controller in our Tahoe in anticipation. From the reading I've done it looks like a typical electric brake electromagnet looks like about 4 ohms so for two brakes the current draw for a full 12V brake application would be 12/4 = 3 or 6 amps total. I'm thinking to get a 2ohm power resistor and connect it to the trailer jack and check the voltage applied. I'm assuming the brake controller will think there is a trailer connected and apply a voltage, at least with the manual brake controller lever.
Anyone ever done this kind of check?
