JH2112 Jeff, Remember these general rules:
1 - if uncomfortable around something, mitigate it so it will not hurt you. I.E. kill all power when testing circuits for things like shorts, even 12V. It takes mA not mV to kill.
2 - ask for help. It's better to ask for help than to damage something. It's OK to try yourself and ask for verification. That is how we learn.
3 - when all else fails, step back, take a deep breath, and walk away before you start throwing things. Sometimes taking a breather will allow your mind to "loose focus", which in turn allows us to see the real problem or solution. Even taking a breather when something is not fitting or working like it should give the body time to reset.
Never forget we are all here learning. No one knows everything. When you stop learning it's a bad thing.
If you are uneasy working around 120v stuff, check out something like https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 which will allow you to test the circuit for both volts and amps and keep the wiring shielded.
I just picked up a https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 so I can test DC amps as well as AC amps. If you do not have a meter, you may want to consider something similar. I chose that one due to the ability to test DC amps as I still do a bit of automotive work.
I'm going to guess you have Dexter axles (look for the tag to verify). I use this manual when I need to reference something for the axles: https://www.dexteraxle.com/user_area...ice_manual.pdf page 15 starts electric brake stuff.
When you ohm the magnets, using 3.2 ohm per magnet you should get about 0.8ohms for the 4. (page 21) Looking on page 10 you will see the TV side of the plug, mirror it about a vertical line (verify which way the notch is) and test the brakes here. Ground is common to brakes and lights. I suggest starting at the plug and working toward the brakes. Inspect the wiring where the pigtail to trailer junction is located.
