Fresh water electric drain valve wiring diagram

[Bernard J. Wooldridge]

We have a 2005 Beaver Monterey, m-series, with a cat c-9 engine, I discovered the electric drain valve on the freshwater tank has no 12v to it, so I am looking for any information for  that circuit in regard to fuses, relays  etc. and their location....thanks, B. J. Wooldridge  (jerry)..

If your drain valve is made by Drainmaster, there might be a fuse behind the switch, or next to the valve.
