Wiring Harness Can Be Operated By A Standard 12-Volt Battery Charger
Jeff Kumpf, Hopedale, Ill.: "It's always easier to work on trailer lights when they're energized. So I made a wiring harness that can be operated by a standard 12-volt battery charger. The green and yellow leads are attached to a double-spaced flasher, and the brown lead goes straight to power. When a trailer is hooked up to the battery charger, the tail lights come on, and the brake lights flash as if the hazards were energized. This makes them much easier to repair, and I don't have to work out in the cold while making winter repairs."
