Ok. Just Cut the power wires to the first axle there I had 12 1/2 V. As soon as I hook up the brakes to the front axle only it dropped to 10 1/2 when I hook up the rear axle to the furthest away wheel I’m still at 9 V.
I’ll do a road test next and see if all new brake assembly’s has improved my breaking. So glad I have an engine brake on the ram.
There is still some seriously high resistance in the wiring, I would have expected no more than .5V drop and even that would be high.
If you have some 14 or 12 gauge wire hanging around, might be easier and faster to bypass the wire from tongue to the axle as a temporary test. You could feed the test wire through a window at the front and then out a window nearest to the front axle. Doesn't have to be super fancy for a test. Heck even a 14ga or 12ga extension cord could be employed and if you didn't want to cut the connectors of the extension cord you can make some adapters to connect it temporally.
Sometimes it is not worth the damaged brain cells to fret over the junk wire used by RV manufacturers and abandon it.
