IBC amperage

[GSchlegel]

I have read the electric brakes on a trailer should see 3 amps each. I tow a Boy Scout trailer occasionally and can't get the brakes to lock up. My controller is set at a gain of 10, heavy electric. While I had it in the dealership for the water pump recall and transmission fluid and filter change, I had them attach a tester to the 7 pin. At max brake using the manual slider it indicated a bit over 12 volts and 9 amps. It was set for 2 axels.

Does that seem right and the problem is in the trailer wiring, or is there a problem with the integrated brake controller?

Most likely the problem is in the trailer. When was the last time the hubs were removed for a proper inspection? Have they been adjusted? Many points of failure for electric brakes: trailer plug, trailer wiring, each connection outside the drums, connections inside at the magnets, inside the axles and at each point where the wires enter or exit the axle tubes.

Magnet amperage should be 3 amps per magnet/wheel or 2.5 amps if you have the small 7" brakes.

The integrated brake controllers are extremely finnicky when it comes to proper amperage. Both my 5th wheel and flat deck trailer brakes worked with my 98, when I bought my 14 I hooked both up immediately after my 98 and got the"trailer not connected" message. Landshark has a lot of good points to check out. Any connection that looks suspect needs to be addressed.
