SeeLevel Install - No Love

[digNbubbs]

I did an install of the new SeeLevel 709PH that I recently purchased. The instructions seemed very straight forward, but it seemed more difficult than I had planned in my little brain.

I have a 2006 Monaco Knight. The biggest issue I am having right now is that two of the sensors - black and grey - are showing open (OPn). When this first showed up, if figured loose connection. I changed the connections - black and grey sensor wires twisted together, crimped into a butt connector. Wire running to panel - twisted and in the other side of the butt connector. The fresh tank uses a saddle tap connector and reads fine.

I have had intermittent readings on the black and grey tanks. It showed a number for a while, and I checked the sensor strength and got over 60% for both of them. Next time I checked, they both showed open. I know that sounds like a bad connection, but I metered the wires at the connection and they were both solid. The connection for the fresh tank is downstream of the black and grey connection - meaning the fresh is the first in the line, then black/grey, then the monitor.

The instructions mention to short out the sensors to test that they show short (Sht). Does anyone know how to short them out? Any thought on how I can be sure that I am tapped into the correct wire at the monitor? It 'seems' like the correct wire, but I suppose anything can happen. I used the blue wire that runs to the monitor for the fresh water tank.

Also, I didn't tap the wires for water heater or water pump, as I was not positive which ones to hit. The instructions say "Heater power output" and "Pump power output". Not sure what side of the existing switch to use.

Thought, tips, suggestions, and taunts will all be welcome.

Kev, you can take a long piece of wire and short out the leads to the sensors to ground. This should give you the "Sht" reading you were asked to look for. On the original monitor the switches for the water pump and water heater will have two wires each. One is 12+ volts and the other is the load. The "output" of the new monitor should be connected to the load wires of the previous monitor. Good luck and let us know if we can help further.

Kev, I had some problems with my SeeLevel Gauges when I installed them, too. Turned out one of the sensor strips was bad. I called SeeLevel and they were very helpful in wakling me through the diagnostics. They sent out a replacement sensor right away.

I think I would smile seeing "sht" on the panel that reads the level of the black tank! That's some sensor!

Now that's funny
