Has anyone split the wiring harness to left and right brakes with a 12 gauge power wire to feed the brakes on the right ?
To the split the harness question, yes I have. See here. I went no 10 gauge.
Now to the problem short of a total rewire
Odds are high you have bad corrosion in the connections or possible the wire in the axle tube is brittle, cracked, chaffed, wire exposed from insulation and doing a partial ground out of the connection.
Here is problem area 1
Problem area 2. On mine they spliced in the power feed and stuffed it between the tire and frame. And the ground wire is there too for the rear axle. Nothing like having road wet and yuk land all over ones brake connections....
You might be fighting a bad ground pending where you took the voltage. The brakes are wired to a frame ground. Even if the hot wire is good, if the ground or connection is all corroded it cannot complete the connection.
Good luck. Since hubby came back with all those good voltages, he can hunt this one down with some pointers on where to start the hunt.
