How to Test Brake Magnet Amperage on a Trailer with 4 Brakes
Before you test the brake magnets individually, disconnect the trailer from the tow vehicle. Next, sever the brake magnet wires and connect the ammeter between the positive battery terminal of a separate 12 volt battery or 12 volt independent power source and one of the magnet wires. Then, connect the other magnet wire to the negative battery terminal. For 10 and 12 inch brake assemblies, each magnet should read 3.2 to 4.0 amps at 12 to 13 volts. For 7 inch brake assemblies, the magnet should read 3.0 to 3.2 amps.
If the amperage readings are greater than the specified amounts, replace the magnet(s). If the reading is less than the specified amount, the leads are bad and the magnet(s) should be replaced.
