2008 Dynasty Fuel Gauge Problem

[DCTENT]

Since New, My fuel Gauge would Only go up to 3/4 Full, So Like A DUMMY I had it fixed by replacing Sending Unit, NOW When I turn Ignition on gauge goes to Full & will not come down, I have Checked wires into Tank, I have NO power going into tank, Has anyone had this experience & know what too do?????????

1. You might have blown a fuse in the fusebox...thus no power..in changing the sender.

2. You somehow might have a bad ground..

These are educated guesses and may or may not be correct.

Can't you take it back where it was fixed the first time and say it still doesn't work? Sounds like you should still be under their warranty.

DCTENT,
Sounds like Stuart has the right idea. You could isolate whether it is a faulty ground or no 12v by making sure the - lead of your multimeter is attached to a known good ground. Without validating ground testing via the ground at the sending unit may send you down a bunny trail. According to the Monaco wiring diagram for my Endeavor there are 3 wires: Ground +12v and dash guage wire. Maybe a dumb question but have you tried to adjust it? Sometimes the adjustment pots get crud on them which screws everything up.

In response to Camelot Camper, I called Chesley In St Paul Mn, They want to install another Sensor as they claim Sensor must be bad (COULD BE) But I doubt it, In response to Stuart & Mark, I had a good ground when testing, However I only have Two wires going to tank not the three as Mark has. I have been told there is no way to make any adjustments on Tank Of New Coaches as they were able to do on Older Coaches.
Thanks for the Help Tho!!!!
By the way I have asked Monaco for Schematics on the Coach, They Claim they do not have any Manuals. & of Course the Manual I Do have shows nothing like that
