Having trouble with mine. I have my 7 pin wired up correctly, through a 5 to 4 converter and im getting voltage and continuity through all the right pins and even when I used the 7 to 4 adapter I still get voltage, but its only 8 volts, not 12...even still I don’t get stop or turn on the trailer at all. I measured amps and I think I’m getting 300 mA on turn, thats only 2 watts but I don’t get anything...like ZERO light. I should be getting something, even with a lousy 2 watts, right? For the record it used to work, and now it doesn’t on 3 tested trailers.
