Slow laboring slides

[spindrift19]

I’ve searched the forum but can’t seem to find a solution to my Eagles issue. We have an Eagle fifth wheel that we took across country this summer. When hooked to 50 A service everything seemed to work fine. More recently I’ve noticed that when hooked to 50A the two big slides are very slow to extend and retract. One is the schwintek, the other is not (can’t remember the names but it’s the two bars under the slide with teeth). I noticed this weekend when I got it home that when plugged into my house using a pigtail and an extension cord from my garage the slides work much faster. Does anyone have an idea as to why this might be? Shouldn’t the 50A give the motors more power than my garage extension cord? Is there a fuse that the 50A uses that may have blown, but the other cord doesn’t use? Sorry for the long post.

How well do the slides operate on the batteries?

It seems to be slow.

If your control panel says your battery charge is good, use a pair of jumper cables and add a ground. Go from battery negative to chassis and try the slides again
