Does anyone know where I can order one of these? The tank level buttons seem to not light up the lights, ( they do on occasion intermittently ). Its def not a fuse or loose wire.
Thanks for any help

More than likely your problem isn’t the board - it’s that your tank sensors are coated with “muck” (for lack of a better word).

You can - after insuring your tanks are empty - access the sensors and either clean or replace them, or you can do a YouTube search on “poo pyramid” or “the Geo method” to get your sensors cleaned up.
Using the Geo method will takes time, it won’t fix your problem over night or in 2-3 days. But it will eventually break the “muck” off the sensor.

You can also test if the sensors are at fault -

First, assuming the sensors tank sensors are accessible - connect a jumper wire from the bottom tank sensor to one of the remaining sensors for the same tank. Then depress the levels button for that tank.
A light for that tank and sensor level should now light up as bright as it was intended to light.

The way these level systems work is they rely on the conductivity of the fluid in the tank. The bottom sensor is at either ground or battery potential, and as the fluid fills the tank and comes into contact with the next sensor, a current flows through the fluid and back to the control board circuitry and turns on the light for that level.
If the sensors are “coated”, then the resistance will be too high to allow enough current to flow to light the light.

The Geo method will help solve this.

Thanks for the reply, MrMark52
The Black seems to work 90% of the time. The others not at all...unless I takeit apart and push these buttons or wiggle them around. But completely assembled ...nothing. Ill prolly just go with the Sea Level but I wanted to give a new board a try first if it was easy to purchase.
As far as the sensors being coated it certainly is possible. But Ive always done my best to keep them clean...using products with clean water for the drive home after emptying, etc.

For a 2019 coach I wouldn’t think the board has already had a component failure.

From your statement “ ...unless I takeit apart and push these buttons or wiggle them around.” tells me you either have a wiring/connector issue or it’s possible those button switches are of a low grade quality. Replacements are pretty cheap and can be easily installed.
But my bet would be on a bad ground bond wire connection at the board, followed by bad button switches (due to internal tarnish), followed by fouled/tarnished sensors.

I guess my bottom line is my bottom line won’t support the high cost of SeeLevels relative to what I see others who have them still have issues.

Good Luck in your search or replacement! :smile:
