urbanhermit Report post Posted February 26, 2021 (edited) 1999 Itasca Sunflyer 34: between visits to the coach slides and jacks became inoperative, as though they aren't there. Ground switch on the parking brake pedal works No continuity from the end of it's ground wire to known ground. A 20-amp push breaker labeled for slides and fog lights was tripped. When reset the fog lights worked but the slides did not. Later found the jacks inoperative. On the jack control panel the On and Brake Off warning lights come on when the On button is pressed but go out immediately when pressure is released. Besides a fault on that panel would not affect the slides. Batteries are fully charged, ignition switch in correct position. Question: is there a single relay for both slides and jacks? Could be -- they aren't used simultaneously. I realize how narrowly focused this issue is -- but has anyone had a parallel problem and found the solution? .

dickandlois Report post Posted February 26, 2021 (edited) Urbanhermit, The attached information might help you get the correct info on you coach setup. Let the group know what chassis you have and if it is built on a Ford, Chevrolet or Freightliner chassis and the make of the Jacks and slide controls. Rich. I just found some of the slide out information. Edited February 26, 2021 by dickandlois Share this post Link to post Share on other sites

f442485 Report post Posted February 28, 2021 The ground signal maybe coming from (going thru) a relay. It also maybe a shared circuit relay. I would be looking for the relay that operates the jacks to see if it is defective. Just a thought Share this post Link to post Share on other sites
kaypsmith Report post Posted February 28, 2021 Ground safety circuits often use multiple relays to make sure all conditions are met before allowing the circuit to complete. Make sure that there is no problems with any thing before supplying a ground source to over ride a system. If the over ride works momentarily, then start backtracking the circuit to find the failure point. Share this post Link to post Share on other sites
richard5933 Report post Posted February 28, 2021 I must have been reading too many safety threads recently. On first glance I thought this thread was about a coach that slide off the jacks and killed someone. Glad to find out it's 'just' an issue with the electrical system. In my experience, the vast majority of electrical problems wind up being related to ground connections. They have an amazing way of looking great but being electrically horrible.

urbanhermit Report post Posted March 7, 2021 Thanks to all who responded with suggestions. It turned out to be a loose nut on a wire terminal on a solenoid. Whew! Enabled me to sell the coach two days later, 12 hours after I posted it on craigslist. Bittersweet -- I liked the interior layout and atmosphere better than the bigger, newer, Monaco Cayman we still have and will keep. BTW, the problem was with a Itasca Sunflyer 34 with the Ford F53 chassis. Share this post Link to post Share on other sites
