we need to tow our vehicle with the Motorhome but the hitch connector from the 94 Grandvilla U280 36' is dead even when turning on the lights for testing it and there's no voltage on it, I checked under the dashboard for the fuse locations, but nothing about the hitch connector, does anybody know where is the fuse located or knows how to fix it? Thanks!
Each circuit has its own fuse in the dash panel.
The turn and brake lights go through a diode box , /"combiner",/ "euro to US converter" . NAPA has them for abuout 20$. Find the box , near the tail lights,, and check for power into and out of the box. The running lights circuit goes straight through without modification . Start there and double check the fat white wire for a solid ground at the frame rail.
Use a test light rather than a voltmeter and clip the alligator clip to a known good ground source ( 2x2 hitch receiver is usually good). You need to make sure the ground is good first.
