magnet resistance
Any one know that the ohm valve should be across a brake magnet
Forum Discussion
It will be roughly around 4 OHMS... BRAKE MAGNETS will draw 3AMPS DC current when a full 12VDC is applied to them...

Keep in mind all of the BRAKE MAGNETS will be wired in parallel so that will have to be taken into account if you just throw a OHMS meter across one of them...
I would not want to unsolder or disconnect a BRAKE MAGNET just to measure it's coil resistance. That could create even more problems...
I use a Sears CLAMP-ON AMPMETER around the one DC cable feeding all of the Brakes and hit them with 12VDC. Then if I have a single axle (Two Wheels) it should read 6AMPS or 12AMPS for a dual axle (4 Wheels)...
My BRAKE MAGNET emit a faint audible tone noise when they are activated. Others will use a CAMPERS COMPASS up close to the BRAKE MAGNET and look for the needle deflection when 12VDC is applied.
