Fuse for breakaway switch??

[rbs]

Repacked bearing, and checked brakes and in the process determined the breakaway switch was not working. Tested fine for getting power, but when pin was pulled would not activate, was not getting power to the brakes. Ordered, checke the new switch, installed, but still not activating the brakes, although meter shows that when the pin is pulled the brakes should be getting power. Is there an inline fuse somewhere that preventing power from reaching the brakes?

Check for a broken wire.

They usually don't have fuses in them.

There should NOT be a fuse for the brake away switch. When that thing needs to work it needs to work! If you were to find one on your unit it needs to come out and be straight wired.

Did you confirm that the brakes were working at all? If they work during normal use with the controller but not with the new brake away switch then the wire from the brake away switch needs to be checked, it may be a loose connection were there is a wire nut or a broken wire... There should be no fuse.

If a voltmeter showed voltage on the output side of the switch it is not a question of a blown fuse. Are you sure you tested both sides of the switch while the pin was removed?

First thing to do is jack up one wheel and while someone is turning that wheel take a short piece of #12 wire and connect the terminals at 1 and 5 o clock on the umbilical cord. If the wheel stops the wiring normally used from the tv is good. Spin the wheel again and pull the pin on the switch. If that does not stop the wheel there is broken wire from the switch to where it connects to the brake wiring.

All 4 brakes work when activated by vehicle. Getting power to switch and to the brake side of the switch when the pin is pulled. I will jack up the tires to see if brakes activate when switch is pulled. I was listening for the magnets to engage and was not hearing that, not spinning the tire. I will give that a try as soon as it stops raining, then go from there.

Sounds like the wire leaving the break away switch is not connected to the brake wiring. Look for a junction box or a place where it would be spliced into the brake wiring.
Use a meter and check for continuity between the wire at the break away switch and the wires at each brake.
