Hydraulic slide problem

I have a 2010 Montana with 4 slideouts that are all controlled with 1 switch. when connected to electric I have no issues, but when on battery power the last slide comes in probably 6 inches then stops, I let off the switch and then press again and it comes in another 6 inches. I keep this up until fully in. Naturally this is the LR slide that is the largest and heaviest. I think it is a battery capacity issue but just want to know if anyone has experienced this and what they found out.

    As far as charging goes, I have just replaced the converter with a new 3 stage converter, the original went bad, noisey and not keeping steady voltage.
    I will check the battery out real good, it might not be the right battery. May need a battery with more amp hours.

    You need a new batt and need to clean the railsand use some dry lube


    That's what I am leaning to

    But the fact that it only does it when not on shore power may indicate a weak battery. If battery voltage is low the pump will draw higher current making the problem worse.


    ^^^^ This. Weak battery causing breaker to trip. If you trip breaker too much it will have to be replaced also. Start with the battery.
  • I agree about the weak auto reset circuit breaker. Common problem on Montanas with hydraulic slides. Needs to be replaced since it burns the contacts a little each time it does that. Cheap and easy to replace.

  • Very common...you have a weak breaker. They are auto resets and trip when the get warm/hot. After 3-5 seconds they cool enough to auto reset and then work again until they trip again....a $10 fix.
    Look for it/them on the positive cable coming off your battery.
    There may be 2-3 of them. Have someone else hold down your slide button
    and you put your fingers on the breakers. You'll feel it go click when it trips...that's the one you need to replace.

  • I assume Lippert?, I had my battery go bad and it would not work when plugged in or on batt, just chattering noise.
  • Sure sounds like a battery problem. I always have power plugged in when I move the slides, either running truck or shore power. It puts a little less strain on the batteries.
