Mystery Switch

[Mike n Marty]

We have a '13 Tuscany 45 LT. In the rear bathroom, back wall , next to toilet is a toggle switch that illuminates red when on. Nobody seems to know what it is. I thought an engine preheater, or possibly a black, grey or freshwater heater. Any idea?

If I’m not mistaken, from previous posts, that is your engine block heater. I could be wrong so you may want to search the forum because it has been discussed before.

Absolutely engine block heater

Check your panel for amp draw with the switch on and off.

If you don’t see about 900 watts draw, your element is burnt-out or not connected.
