when I turn the key on the temp gauge bottoms out (points straight down) and the red light by the gauge comes on and beeps once. I had the problem with another like bus over a year ago and I believe I replace the sensor by the thermostat. Replace the same sensor on this one and the gauge still bottoms out. Thoughts?

pretty sure I found the problem in the harness, ohm check checked out fine but one wire will not light up a headlight. must have a few good strands but will not handle a load. going to dealer for replacement since it is under warranty.
