I'll break the ice.
If I turn on the switch for our vac. it goes on weather you have a port with a hose in it or not. I have purchased to new hose ports and they have two brass tits in the opening and when you shove the metal end of the hose in it is only then that it should go on.
We have 2 ports for the hose 1 out and 1 in. I have tried every way to mess with the smaller wires that hook to them, to no avail. If the switch is on, it runs, hose plugged in or not.
The on/off switch is in the bay with the vac itself so if vacuuming inside it stinks. I am considering installing a 3-way switch and then there would be a switch inside at that hose port too. I would prefer for it to work as designed.
Anybody have any ideas?
