Holding Tank Heaters

[klcdenver]

Need wiring diagram/instructions for holding tank heater.. These are small pads about the size of a quarter with a single small wire going to them. Sorry could not get a photo to attach. They are mounted on my 2007 Diplomat 40SKQ. I need to know how to troubleshoot them and their source of power etc... My cargo bay heater is working correctly but not sure about pads. Thanks for helpful info.

This is a typical pic of the heaters.

Thanks for no answers. Duh these are holding tank level sensors.

I'm confused. Your first post referenced 'holding tank heaters', but your photo and further description sounds like you're talking about the holding tank level sensors.

I thought the tank level sensors where heating disk at first. I have it all figured out now. I do not actually have heating pads installed at this time like I thought. On order now.

If your cargo bay heater is working why do you want to add tank heaters?

Ditto on tank level sensors. You should have a thermostat controlled heater hanging close to AH in cargo bay.
