Outstanding video, as a dealership technician it is the info I needed to assist my customers with trailer problems, and not just stop with "it's not the truck ".
-
Great tip on the magnet wear. I have one side that has completely worn down and never gave it a second thought until you mentioned it. Thank you!

Back to your problem of unequal braking. These brakes will need adjusting every year to get them working with the same pressure. E trailer has good short videos on this. Thanks for the great video and keeping it to the point without making a TV show out if it. DS

Thank you for your efforts and video. Very informative and descriptions are perfect! Very well put together, and I can learn from anyone. I've been playing with drum brakes since 1971, yes been around a while. But! I am brand new to the electric brakes, and never had any apart before. I am adding brakes to my 3500 lb single axle trailer. Not that I couldn't figure it out, I enjoy going over the work that's ahead of me. For me this is an excellent refresher course, and thank you very much.

You must also unhook the wires, isolate each coil, to check resistance

Love that the illustration for the 4 and 7 pin connectors looks nicely computer generated but the Like and Subscribe sign is just, well, homemade!

Great video. I'm about to tackle the brakes on an old stock trailer. I think I know enough now to get it done

Nice meter. Wish I could afford one. I'm going to give this tip. When working on trailer electrical, ONLY connect the electrical. In other words, don't hitch it up. No mechanical connection to tow vehicle. This will help with diagnostics, particularly on the ground side where most problems occur.

Great explanation. Thank You !
-
Great video. Well done.
-
Great tutorial on the trailer brakes. I've got one locking on a dual axle trailer. Everything mechanical seems fine. I suspect an electrical issue on that wheel.
-
No description of what to plug into on multimeter.
-
nice video I'm getting a weaker amperage at the brakes when using the brake pedal as opposed to the the controller switch even with different vehicles ...... any thoughts
-
I have a 7,000 lb two axle trailer. Both axles have brakes and I can’t hookup both axles to my brake controller, only one. Is that because of my ( cheap) brake controller? Very good video.

Great video
-
I missed how you determined if the truck activated the brakes? Where do you get the specs for the amps & ohms?
-
@ 9:10 if you didn't disconnect the wiring between the two magnets, you are measuring resistance of both magnets at same time.
-
Most of that right wheel was in the dark.
-
is it really working on the actual scenario? it must be actually running and apply brakes if it really brakes?
-
Very nicely done. My only question is: did you connect the magnet wires when testing for amps? If you’re concern is one side grabbing more than the other- id like to think the amp test should be done while under load (ie: in this case just spinning the wheel “assembled” THEN noting the amp readout)?
