Update: Finally had some down time to replace the water tank sender. In general it is not difficult to accomplish. However, if you are doing this I've learned that there are some key steps for finalizing the install that are not obvious in the instructions:
- Assuming you have mounted the sender in the tank and connected the control wires, you most likely will see that the gauge still won't
work correctly. I learned that the factory doesn't tighten the set screws that hold the two rods in place on the sender top unit. There is a hex key in the package and once you have tightened the screws against the rods the sender will begin to operate properly.
- Using a small straight slot screwdriver you then must make adjustment to a small potentiometer on the top of the sender unit. It is easier to for two people to accomplish - one on the tank top and the other providing readings on the tank gauge.
It is obviously helpful to know what the water level in the tank is before making the adjustment. Best to fill the tank completely before attempting.
Happy New Year to all.
