Our 2000 Royale uses Headhunter's system to monitor the fresh, gray and black tank levels. It is two systems, one for the fresh tank which also has the auto shut off feature and other unit that measures the other two tanks.
Over about a year all three quit working correctly. Headhunter sent me a troubleshooting guide. I followed the instructions and found by the instructions two of the tank sensors failed. I ordered two sensors for about $900 Lewbucks. One new sensor did fix the fresh water system. After the other new sensor was installed it did not work because the voltage to the sensor droped from the required 8 volts to less than 3 volts. I am now told the gauge unit power supply is bad. To end my troubles the new gauge unit is almost $400. I am not certain my third tank sensor is good. If not this adds another $495.
What system do some othe the other coaches use?
I have found a complete SeeLevel II by Garrett Technologies monitor system for a total of $465 for all three tanks plus battery voltage.
Does anyone have any experience with a SeeLevel II?
