Gauge turning off for a little while?

The two ground wires need to be separated otherwise you will induce a lot of noise into the system possibly causing erratic operation. The white and black should be completely separate all the way until a the grounding lug, at that point you can put them in the same lug. If you are tripping the failsafe the yellow light will come on for 4 seconds then go off unless it re-trips right away. Make sure your WL and WH are set properly.

Again, if you unplug the level probe it will eliminate that from the possible issues.

Make sure your ground terminal for the black and white wires is at 0 OHMS to the chassis or battery negative. Any floating issues will be picked up as noise.

I have the 2 ground wires running along side by side and then twisted together & crimped onto one lug. Should I run these wires away from each other and put seperate lugs on?

Yes it is coming on for roughly 4 seconds, but why would the failsafe trip and just cruising speed?


I'll double check the resistance from the chasis to the plug and see what OHMS its reading.

I have unpluged the float sensor but haven't driven around with it off to see if its the problem. Should the Yellow light come on straight away if I disconnect the float sensor?

Thanks for your help.

If the level sensor is unplugged, the system will think the water level is full. At this point the only reason for the yellow light to come on will be the failsafe.

The black and white wires can be run as you have them but check the resistance to ground.

How did you set the failsafes? What are the positions of the WL and WH?

Ok, I'll check the resistance today at work.

The WL arrow is pointing jus before 12 o'clock and the WH arrow is pointing just After 3 o'clock.

That failsafe window sounds a bit narrow. How did you arrive at those settings?
