What is switch for?

[Jackie Berg]

I know the left one is for the water pump but can't remember what the other one is for. I flip it and get nothing. Thanks

[Lakota Wolf]

Have you ruled out the possibility it could be for the water heater? Dodge Tioga had 2 switches,, one turned on the 12V water pump and the second turned on the water heater (On a gas electric combo water heater)

[Jackie Berg]

My water heater is gas only. It hasn't seemed to affect the operation of anything major in two years so ???. Maybe I'll try and track down the previous owner cause I know he told me what it was for. I just can't remember now. Thanks, Lakota

hey jackie. not sure on the age of rv, could maybe it had a air compressor for water system. i have a winnebago chieftain and it had a spot for it. just a thought. next is hand over hand and follow the wire. take care. 

[Lakota Wolf]

Like Dave mentioned,, older RV's with the ole steel tanks needed a compressor to compress the tank to move the water under pressure.,,, If You have the * Old steel tank, check to see if there is a compressor or old wires leading to the fact it did at one time have a compressor there.

Good point Dave,,,,, I forgot about those old school systems.

 Best I recall EVERY OLD WINNEBAGO I owned back in the day used a small 12 VDC Air Compressor and a galvanized steel tank so the air pressure forced the water out under pressure. It had its own pressure switch that kicked in at like 15 PSI and off at 30 PSI.

 Good catch Dave, its been too long since I owned them Winnies and about forgot they used that method

Or the final guess would be,,as follows,,,,,,, The main switch to the on board * FLUX Capacitor.* 

[John "T" Nordhoff]

 Or maybe it activates the muffler bearings?? Or the kanibbling pins,,,,,,,,,,Or the relicon rods??? Darn if I know

Good reply, John! I was a diesel mechanic in the Army so I know all about those muffler bearings! LOL

We was running out of ideas of what that switch could be for,, and we had to throw some humor in there for good measure. Good luck on the identification.

At least it doesnt control the flow for the headlight and blinker fluids. :-)
