Pump Switch Wiring

I have a 1984 - 31ft Excella and the light for the water pump that comes on when the pump is turned was out. After removeing the control panel I discovered that the black wire that is connected to the light socket came loose from some where. I attached it to one of the orange wiress on the switch that is attached to the control panel it will work ok, but the pump switch in the bath when turn will not turn the light on at the control panel. It work ok for before. Any suggestion where to connect the black wire rather to the hot side of the control panel switch?

Bob, thanks for your concern. My concern is the postive wire for the light on the control panel came lose. I can attack it to one of the organe wires on the control switch the light comes on.and the the pump works fine, but the ligth does not light like it use to do when the bath room switch is on. I just want to connect the light to the right source. I hope I explain myself ok. I have read all your post on the forum, you are very knowledgeabel. Thank you and God bless. Lewmad

Black wire usually denotes a negative or ground connection in a 12VDC system. Keep in mind I'm not familiar with your system I'm just tossing out an idea.

Lewmad,

Do you have a picture you can post showing the wiring in question?

Thanks for answering. No I don't have any pictures. I will to get the control panel down to take them. It has been 100 degress here for the last 2 weeks and it is very hot in the trailer to work and it is stored in the trailer parking area in our mobile home park. Thanks again for saking. Lewmad (I live in the Modesto, CA area.)

The switch has power, load, and light connection. When the pump is turned on, it grounds the light, which turns on. The switch should have tiny markings for which one is which. Generally, center is hot, top is light, bottom is load.

Water pump switch

Terry, thank for your info and reply. I pulled the switch so I could see it on how it is wired. My switch lay sidesway and for the conections, #3 is organe, #1 black (power) and #2 is organe. (#3 and #2 are on each end) I used a jumper from the black lead at the center of the light socket to#2 and tryed the bath switch and the light came on. Turm it off at the switch ok, them turned the on the pump from the control panel but the light would not come on. I checked the pump switch in the bath it has 2 organe on each side and red line going to the pump. Question, did I check every thing ok. I though the light would come on when you used the switch on the control panel. Thank you for you help and God Bless you. lewmad

Terry, I'm new on this forum and I received you message on #8. I wrote back explaining what I did and how the switch is numbered.(9) Did you receive it? If you answered it am I correct that it would show up with my other post. Thank you for your time and God Bless. Lewmad

The orange wires are the "travelers" between the 2 double pole single through switches.

You need to locate a wire in the control panel that is hot when either of the pump switches is turned on. This wire should not be connected to anything else in the panel as it is just the return from the pump.

You can draw a picture of the circuit. Hot lead from the battery goes to the toggle of one switch. The 2 switched legs of that switch, orange wires, go to the 2 switched legs of the other switch. The toggle leg of the other switch goes to the pump and feeds the light. The pump and light are grounded.

If I were looking for the wire that feeds the light at the panel I would look to see if there is a 3rd wire coming to the panel with the orange travelers coming back from the bathroom.

Yes, but Airstream kind of does what it wants to. On both my 71 and 73 black is a hot 12v wire (along with red and other colors). White is ground or negative. Green may or may not be a ground wire. Now maybe in later years they conformed to code.
