Waterpump switch on the 1964 Safari

Hi,
I have recently acquired a 1964 safari and am trying to get the 12 volt system up and running, which I have achieved with the exception of the Waterpump. I can't get it to work and before I pull it out to see if it's repairable or. Reds replacing, I would like to know if there are any switches that I should Be aware of?
I would have thought there would be a switch in the galley area but can't find it and can't see one on the pump although access is tight at the moment.
Thanks in advance from a Airstream newbie from the UK, what a great informative forum
Jim

I think, in those years, they used a relay to power the water pump. That is a 12 volt line went to the relay, which was near the pump, and the coil of the relay was all that was activated by the pump switch. In later years they eliminated the relay and just ran all the power for the pump through the pump switch.

Some switch in the galley should have powered the pump I would think, but it also could have been in the bathroom.

That said, in almost 50 years since the trailer was made, who knows what previous owners may have done to re wire things.

Thanks for the prompt reply,
I didn't find any relay in the system so maybe this has been changed by a PO, I am hoping that I don't have to pull the trailer apart to find the elusive switch!!!

In our 64 Globetrotter, the switch is on the wall behind the sink to the left of the window. It looks like a regular house light switch. It is usually hidden by the curtains. The PO had replaced the water pump with a 12 volt only pump, so on the control panel in the rear compartment, where you would switch between city power and batt power we have to leave the pump on batt power. Good luck.

Thanks for that,
I have found the house type switch to the left of the window but it operates the patio/scare light, so maybe this has been changed in the past, but I would be surprised if that was the original water pump switch as it has a 110 outlet next to it and I wouldn't want to operate a switch next to the mains with wet hands!!!
so as of now I am still searching and very intrigued.
Anymore ideas??

50dodge,

Are you using the original air pressurized system?

If the old grey cells are working properly the 12v pump switch was on the front wall, left side next to the window on our 63 Safari.

There is also an air pressure limit switch on the air compressor.

I don't have an air compressor so I guess its not a pressurized system in the 1964 model, nor is there a switch on the front wall, it would appear that no two of the same model were wired up the same, it must have been a serviceman's nightmare!!
I may just bypass the original wiring and put a new feed to the water pump and install an inline switch......at least I will know where that one is!!

50dodge,

More than likely it was changed out at one time.
Our tank and pump were in good shape when we got the 63 and when the pump failed I just replaced the the 12v compressor.

Have fun with your up-grades.

Bob

By now you've probably found the switch. Our pump switch is under the window on the street side, just above the back of one of the couches. It's shown there in the manual, maybe yours is in an equally unintuitive location?

well I never, i eventually got to the root of the problem and globestream, you were right on the money.
the po had changed the electrics about so that the scare light operated from the switch over the sink, I have now reinstalled the wiring to its correct configuration so a switch by the door operates the scare light and the switch over the sink operates the water pump.

Many thanks for all your replies, the input was helpful and i also got to get intimately familiar with my safaris electrical system.
