tank heaters
My brother has a Cardinal 5th wheel travel trailer with arctic pkg. It has 2 grey tanks. Does 1 switch control both grey tanks? The switches are not labeled. Thanks to anyone that knows.

- Thanks Old-Biscuit. That was what I was thinking but wasn't 100% sure.
- 1 switch for fresh
1 switch for black
1 switch for the 2 grey - he has 4 tanks total. fresh, black & 2 grey with 3 switches. Can't check it now. He is here in Az escaping the winter & his trailer is in storage in Ind. Thanks for the reply.
- Therein lays the problem......depends on what was installed.
Some of the 'arctic pkg' consisted of heat pads on fresh tank and all waste tanks.
1 switch controlled fresh and 1 switch controlled all on waste
(fresh tank pad used blue& white or black & white wires on switch-----waste tank pads used grey, brown or green wires on switch)
ALL pads the same and pull roughly 7A/each.
Thermostat controlled.....which switches them on at roughly 40*F and off at 60*F
If only 1 switch then it is for pads on waste tanks
