Troubleshooting Voltage on Hopkins Custom Trailer Wiring for 2013 Ford Focus

Question:

Trailer wiring for 2013 Ford Focus. I installed the wiring kit, Hopkins Plug-in Simple Wiring Harness with 4-pole Connector HM11140545. Ran the 12V wire from the battery, attach ground. Measured 12V at the converter module between white wire - and red wire +. Checked voltage at the 4 terminal connector,measured from white wire. 1 all lights off voltage at connector= .5V. 2 headlights on green and yellow = 12V. 3 left turn signal, green, yellow, brown = .5V 4 right turn signal, green, yellow, brown = .5V any ideas?

The Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM11140545 is a confirmed fit for your 2013 Ford Focus. I recommend checking your wiring using a incandescent circuit tester like # PTW2993. Sometimes using a multimeter will not give you the draw on the wire needed for an accurate test if the lights are not on. Test each function at the 4-way trailer connection as the signal will be amplified through the converter to make the lights function correctly when the converter sees the draw on your light functions.
