What is normal resistance reading for 5er brakes?

My 5ers brakes aren't working. Trying to figure out if it's the truck (2011 Silverado HD) or the trailer (Voltage 3950). While doing continuity checking of the cables and connectors, I disconnected...

I've been rethinking the resistance calculation I wrote about above. Where I did the measurement, I would see the full current draw from all brakes - 6 x 3 = 18amps. The would imply a resistance of 12V / 18amps = .66 ohms. I got 3.3 ohms.

Maybe the problems is the trailer. I'll find out of someone will let me plug in their 5er.

How could I get a higher, but not infinite, resistance??
