We have 2 ports 1 in and 1 out. The switch should be able to be left on and only when you stick the metal end of the hose into one of those ports and connect the two metal contacts with the hose end should it go on.
The only way to shut ours off is to switch it off. If the switch is on, it runs, weather there is a hose inserted in a port or not?
We have replaced both hose ports with new ones and tried every combination of wiring the 2 smaller wires that hook to them.
The on/off switch is in the bay with the vac. so if vacuuming inside it stinks. I am considering making a 3-way switch adding one inside too but would prefer it work as designed.
Anybody have any ideas?

At both ports check the resistance with a multimeter with the master power switch off. Both ports should be open circuit, but you probably find continuity (low ohms reading). That is why the vacuum continually runs unless the master switch is off. Most likely, you have a short at one of the ports, in the wiring to the motor, or at the motor connection. The port current should be low voltage that actuates a relay at the motor. That relay could be defective causing the motor to run. Carefully inspect the metal tabs at each port to be sure they are not touching the metal elements of the port. |

Thanks Chuck. I'll have to dig deeper to get to the motor and relay. I think I can safely rule out those ports at this point. |

With our "super deluxe" Winnebago, we packed away the 20'
central vacuum hose (and attachments), and bought a neat, small
and light, wet/dry vacuum. It fit neatly into the area under the
dining seat, and served us well for all cleaning chores, including
a major waste spillage.
The central vac is a nice selling item, but the merits of having
a stand-alone wet/dry vac, may surely outweigh it.
Fodder for the mind? |

If it was installed from original and it is still on the bus and is not working it will be repaired or replaced with an improvement. Sorry can't help it. It is like an infectious disease.
We received along with the bus original converters documents, paperwork for every option and accessory on the bus!
Up to now every accessory has been able to be repaired without replacement accept for 1. If the vac is anything like its predecessors I will enjoy having it back on line.
Although alone the unit is trivial but combined with all the other built-ins on the bus it becomes a substantial package. It is one more piece to the puzzle.
We have a hand held that will suck liquid.
I know most of you guys have put together your own buses and you can pretty much pick and choose what you want.
I am trying to practice a little good stewardship with ours. It is a quality conversion with all original components in tact. They are all 22yrs old now and I'm kinda fond of what is there. |

It is also possible that someone bypassed the switches some time in the past. |

Joe Camper -
Like Steve mentioned, the switches may have been bypassed
by the previous owner, in some effort to correct a problem..
With our commercial RV, the hose connector was the faulty
device... well not as much as "faulty", but the wrong end had
the pick-up brush, and the other "wrong end" was being inserted
into vacuum port.
The two metal "contacts" in the port's opening weren't electrical
contacts, but served as a device to trip the actual switch (properly
so, since it avoids shock hazards). The vacuum hose's ends were
slightly different size, and inserting the wrong end wouldn't depress
the two tabs inside the port far enough to trip the switch (with ours,
the "proper end" was plastic, and the brush went on the metal end).
But your's won't turn off..!
If all else fails, I'd try exposing the switches and make sure
the "tabs" are releasing inside the port. Inserting the hose could
be causing them to jam into the "on" position. |

Finally had a chance to look at this again and this is what I found.
Someone previously went and moved some terminals around to get it to run as it does. I moved everything back and it is no longer constant on. However when the wires that lead to the hose port are connected it does not go on either. If I manually connect the contacts at a small coil it will though. There is also a transformer in there.
Question
Is it the coil or the transformer that went bad? I doubt that either are too expensive and can replace both but thought I'd throw it out there anyway.
Thanks
