Slide out control

My signature HR has a single slide out (LR & Kit. driver side). Occasionally, I have an issue with the engine start up, that is, there is a safety circuit that if it senses the slide is out, will not allow the engine start circuit to complete. BTW, the slide is not out, in fact it is in and travel clamps are in place when this occurs. Does anyone know whether this is a limit switch that needs adjustment and where its located? Or is the in/out position stop strictly a motor torque sensor and is it adjustable? Luckily, there is an override switch that I can depress that allows the start circuit to work, so I've never been stranded, but I would like to adjust this issue away, if I can.

  • That is VERY strange.
    So if you boondock, and you want to start your engine for any reason, only way to do it is to pull the slide in first?

    Keep us posted on what you find out, very curious.

  • Good pic. Can you take a pic of the inside controls? Does that cover come off? Doug

    I'll try again since the basic question is still; does anyone know what is the normal method for detecting the position of the slide-out especially the IN position. From what I have already described, there is obviously a lock-out in play here that prevents starting when the control perceives a condition of slide out. Again, the slide is not out, in fact, it is in and manual locks are in place. I want to troubleshoot this issue and would like a place to start. I have opened the slide-out control box. Some relays, integrated circuit components, etc. I don't see any obvious adjustment pots. The control was made for HR by Todd Engineering, but a quick internet search shows no commercial product they sell for RV slide-outs. If nothing turns up here, I may try to contact them and see if anybody has a clue.


    THAT was my point in my post. I have 34 years as a RV Tech (Master Certified) and have worked on and FIXED hundreds and hundreds of slide out systems on almost all makes. I cannot remember when I had a slide system that caused the Chassis engine to not start because of some so-called safety interlock. There may be such a OEM system, but I have never seen it. If Monaco cannot help you, then you will be hard pressed to find anyone to help you. Can you take a pic of that Todd Engineering module? Todd was known for Transfer Boxes and Power Converters in the RV industry and never about slide controls. The Newmar RV's use a magnetic switch on the rack/pinion to detect when the room is closed or open and this is just for the Automatic electric lock arms and not about engine control. Doug

I also have NEVER seen such a feature on the thousands of motorhomes (multitude of brands) I have worked on over the past 34 years and especially since Slideouts have become standard on almost all motorhomesin the past 25 years. What makes you believe your HR has such a feature? There is no good reason to have such a feature on a motorhome. If the slideout is extended and you attempt to drive OFF, then you are pretty stupid if you do not see that slideout in your side view mirrors:B I do believe there are a few brands that have such a feature, but I have never seen them. Where is this override switch located and are you positive that a previous owner did not install it? It does NOT make sense to have such a feature and then have an override switch that negates that feature. Doug


    Firstly, the reason I came to the forum knowledge base was to find out whether there was knowledge concerning such systems and how or if it was adjustable. I do not know whether the previous owner (died) installed such an override switch or if it was a factory installed feature. The switch is located in the center console area ie if you pull the drawer out the momentary push button switch is concealed in the drawer cavity area. What I can tell you other than the previous description of the actions that occur is that if you unclamp the travel clamps, extend the slide, return the slide, reclamp the travel clamps, the problem goes away ie the engine starts immediately. I'm not trying to defeat this feature but only trying to adjust the false alarms that I'm dealing with, OK. You know, the use of such a interlock is not that stupid because IF the slide was not secure, for whatever reason, its not a bad idea to prevent movement (no engine start). Yeah its stupid to have that happen, but you've certainly seen worse, right!!!


    The reason I posted was to let you know that it is NOT standard for that switch. The fact that the switch is hidden shows the previous owner installed it. Since it is NOT OEM, it will be very difficult for anyone to give you help as the previous owner did all the modifications. I would bypass the hidden switch and not rely on the jerry rigged disconnect. IF a slide is not secure the MOST it will move is about 3 to 4 inches. Doug
  • He has a manual lock system. I'd bet the no start is more for that not being properly latched than the slide being fully extended. How many antennae have been trashed over the years (there's an antenna up light on mine), the steps retract automatically with an ignition signal. I've heard of people driving off without unplugging the power cable, heck there's a break away connector on gas hoses, how would you miss taking that our of the side of your vehicle? Stupid stuff does happen.
