A new teardrop owner found unsafe and confusing wiring in a homebuilt trailer, including an indoor two-wire extension cord used for power entry, no ground, and damaged wires where they passed through sharp exterior metal. After testing, the owner identified the interior and exterior lights as low-voltage circuits, while members noted the trailer appeared to mix 120V shore-power style parts with 12V lighting, possibly from leftover trailer harness wire or a previous 12V power setup.

A new teardrop owner found unsafe and confusing wiring in a homebuilt trailer, including an indoor two-wire extension cord used for power entry, no ground, and damaged wires where they passed through sharp exterior metal. After testing, the owner identified the interior and exterior lights as low-voltage circuits, while members noted the trailer appeared to mix 120V shore-power style parts with 12V lighting, possibly from leftover trailer harness wire or a previous 12V power setup.
Members generally recommended removing or abandoning the questionable wiring and installing a proper 15A flanged shore-power inlet, with protected wiring, a suitable outlet, and preferably GFCI protection. Others discussed using a Jackery, adding a fuse block for 12V loads, sizing fuses to protect wire gauge, and planning heavier wire if a future lithium battery or solar setup is added. The owner installed the flanged inlet, switches, and wiring, reported the project finished successfully, and received final suggestions to trim or cover exposed bolt ends with cap nuts.
