front slide motor won't stop!!

FLYING BUTCH · 04-11-2011, 06:50 AM

Hey guys, my 04 Beaver Marquie front slides started not opening or closing without pushing the buttons several times. Now when either side is opening or closing the motor will not stop without me pushing the buttons in the other direction several times to get it to stop. The panel that holds all the relays has two different relays marked for the slide. I removed both of them and tried to work the slides. They wouldn't work so I am sure I have the right ones. I replaced both relays but the motor does the same thing. Is there anything other than the two switches that could be causing this? Very much appreciate any ideas and information.

Butch,
I started to respond to this earlier today, then re-read your comment....and it looks to me that you are describing two different switches (that you push) to get the slide IN or OUT. My RV (indeed most) have a rocker switch with automatic return-to-center OFF position. Please describe your switching system.

Sorry I wasn't very clear, yes I have two rocker type switches. One for each slide. The both cause the motor to stay engaged when either slide is all the way out or in?? I have to keep pushing either one in and out to get the motor to stop running. seems odd that both switches are bad, that is why I am asking if there is something else beside the switch that could be causing this. Thanks for looking at my post, appreciate any ideas.

These circuits are pretty simple: the rocker-switch causes one (of 2) high-current-contacts relays to energize. One high-current relay is used when deploying the slide; The other relay is used when bringing the slide in. When releasing the rocker-switch: the high-current relay de-energizes and the slide motor stops. One slide's control switch and high-current relays (for the "curb side" slide, for example) are completely independent from another slide's control switch and high-current relay.

My thought (and this is a stretch!) --- both rocker switches need to be replaced. But before you do that, here is a test you can do. Gain access to the rear of these 2 rocker switches. You'll note that there are 3 pins on the back of each rocker switch. The center pin has a constant 12 volts. The other 2 pins should have juice on them only while your finger is activating the rocker switch. Suggest attaching a volt meter (set to read 12VDC) test-lead to the center pin of the switch, and the other test-lead to one of the other pins. You should read 12VDC. Now press the switch (you've got a 50/50 chance here...) and the 12VDC reading should fall to near zero (and the slide begins to move). Now..... when releasing the rocker switch, the voltage should immediately return to 12 volts. If (upon releasing the rocker switch) the volt meter continues to show a near zero reading, you've proved you have a bad rocker switch.

As improbable as this sounds, both rocker switches may be bad.
