What's wrong?
The electric brake harness on 2019-2023 Doosan Portable Power Mobile Generator trailers supplies power to the trailer's electric brakes. Those brakes use electrical current from the towing vehicle and trailer battery circuit to apply braking force at the trailer wheels. The battery disconnect switch is meant to shut off battery power for storage or service, while the brake harness needs a steady positive battery connection when the trailer is being moved.
On affected trailers, the brake harness was attached to the battery disconnect switch's positive distribution post instead of the positive battery cable terminal. When that disconnect switch is turned off, the harness loses power. With the harness deenergized, the electric brakes do not receive the power they need, so the trailer's braking support is reduced during towing.
There is no warning sign before failure. The problem depends on where the harness is connected, so an owner or service technician has to inspect the wiring path at the battery disconnect switch and positive battery cable terminal.
