I am sure you should have more than 6 volts when all brakes are applied, but less than 12.5 v; probably 11 v or so. Your ohm reading thru the magnets sounds good. I did a quick google search and the amp draw should be 3 amps per wheel at 12v for a total of 12 amps if you have 4 brakes. Less than 3 amps per wheel you have bad connection. If your wiring ohms out good : almost 0 ohms, you may need heavier guage wire to operate the brakes, although 14ga should be good. Most meters can only take 10 amps so I would do 2 at a time or you will blow the internal fuse in the meter. I am betting on the wiring having high resistance (high ohms reading). Google search ELECTRIC TRAILER BRAKES TROUBLESHOOTING. There is a good answer under about the 4th result. Let us know Good luck, Mark
