Hey Timothy, so voltage drop is pretty common for longer runs of wire if the gauge is on the thinner side. I would assume you probably don't have 10 gauge wire ran from the 7-way to the assemblies? If not, I'd recommend swapping that out with part number # 10-1-1 which we sell by the foot.

Hey Timothy, did upgrading to the 10-gauge wire bring your brake magnet voltage closer to 12 volts? Knowing what change you saw could help others chasing the same voltage drop issue.
