Troubleshooting Curt 55510 Trailer Wiring Harness with Low Voltage

Question

Question:

Installed. Only getting about 7.7 volts out of harness. Ground wire is grounded to chassis. All functions work on the plug 7 volt. When plugged into the boat trailer there is not enough power to run the tail lights and marker lights. Turn signals work, brakes work. Checked continuity between ground and other grounds, solid connection. The converter has always only put out low voltage. Is the converter box faulty? Only a couple of months old.

Your problem could be the converter box. Test the wires on the harness before the box and see if you get the same voltage. If you do then the box isn't the issue and it's somewhere in the wiring before that. In this case you'll need to keep tracing the wires towards the front of the truck to find the problem. If the voltage on the # C55510 harness before the converter box is normal and still low at the connector then the converter is bad.

While we don't have any custom fit trailer wiring harnesses that fit the 2011 Isuzu NPR we can still help with a universal fit option like the #C56175 which you'd have to wire to the taillight circuits of your NPR.

You will need a 1-1/2" wrench like part #C20001 in order to install the nut on the 2" Hitch Ball part #63845. A 1-7/8" wrench would be much too large.
