I can help you figure out what voltage should be coming down the brake output circuit on your trailer.

If you have 10-12 inch brakes you should be getting 7.5-8.2 amps at 12 volts on the brake output circuit.

If you have 7 inch brakes you should be getting 6.3-6.8 amps at 12 volts on the brake output circuit.

If you are getting that voltage and the magnet is still not working, I would check for a worn magnet, a loose connection, or a bad ground. All of these could be causing the magnet to not work properly.

I have linked a Help Article on testing trailer brakes magnets for your convenience.
