.... and still plugged in to the shore power?

seems easy enough to find out... disconnect the battery and try the slide.

are the motor driven or hydrolic accuated slide.
Mine wont the amp draw is way more than the converter will put out.

Ours won't either. After taking the batteries out for winter storage with the slide out, had to use the manual crank handle to bring it in. First time we did that so it was a good "test run".

Ours does but first you have to join the two red wires that normally go on the pos battery post. (somebody on here gave me that tip years ago and I am still grateful.) I use a vice grip pliers for that clamping job on the two wire lugs. The converter has enough oomph to move the slide ok.

I saw in a newer Jayco a warning label that said you needed a battery to operate the slide. I suspect this is only to keep the slide motor pos wire and 'converter' pos wire together on the pos post so there is a path from converter to slide motor. Don't know. Try it out.

All are good answers....my hydraulic slide draws over 50 amps to move in and out....Sticker on trailer control panel says battery must be connected to operate slide.

The gear drive and the hydraulic operated systems I've had in two different 5ers wouldn't operate without the battery hooked up.

edit to add that both motors were operated on 12 volts.

I was told that the amp draw on a hydrolic pump can be as high as 100.amps under load according to Lippert Industries, I do not know about the amp draw on a electric motor type, but I do know it is far more than any converter that is installed in any MH, TT, or 5er, can handle. the converter was desined to charge the batteries and run the items in a RV on the 12 volt side , furnace, gas sniffer, circutry in the refrigerator, a few lights here and there. But as a few have stated go try it. disconect those batteries and hook up to the external power and push that button. I will be waiting for the results of the test.

Our Lippert electric slide (about 13.5ft with sofabed and dining area in it) requires a 30amp fuse on the pos wire near the battery according to the specification handout that came with it. It has that. As noted previously, the converter (Parallax 7355) has no trouble running the slide.

I think it is more a question of how the rig is wired and fused where there may not be a path for the converter to run the slide unless their wires are joined at the pos battery post. With no battery just join those wires with vice grips. Our pos wire from the converter has a 40amp fuse near the battery, so when the two wires are joined the converter feeds the slide motor through that 40amp fuse and then the 30amp fuse.

I think ( because the higher voltage source will do the work while the other source is ignored) even when the battery is in and shore power makes converter voltage 13.8 the slide motor will take its amps from the converter anyway instead of from the battery at its 12something volts using the same path--across the battery without going through the battery.

I am thinking with an hydraulic slide that needs more amps than the converter can supply, then the voltage drop of the converter with the slide motor on would get it down to 12 something so now the battery voltage is "seen" by the slide motor as equal to the converter's voltage so the battery can now supply some of those amps to help out the converter.

Perhaps it is an industry standard to give the slide motor its own path to the battery without going through the DC dist fuse panel no idea. On ours the front jacks don't use that DC fuse panel either--and the converter has no trouble running them either.

I would be worried about leaving the unit plugged in for very long without the battery's in it. I am thinking that the converter might go into a heavy charge mode to bring the battery's that are not there up to charge and burn something out. Please note I am not an expert I just think there COULD be a concern. Eddy

You know that how??? The smallest Converter is 30 amp (no one uses them anymore) most use a 45 or 55 amp converter. The AMP draw of a standard Slide electric motor is about 9 amps. So, the fuse on a slide out system is either a 15 or 20 amp depending on the system. The Converter will supply more than enough dc voltage/amps to run any DC electric slide system without a battery. Of course I know this because I have 30 years RV tech experiance and have worked on hundreds of slide rooms over the years, MANY with dead/ defective batteries, that the only way to extend and retract the room was to utilize the Power Converter. NO Power Converter will be able to safely run a Hydraulic operated room without a good battery connected. A LCI (Lippert) hydraulic pump pulls 45 to 60 amps when running. Doug

The OP has a Jayco (12 volt electric slide). So, yes, his slides will operate without the batteries connected. But it is NOT a good idea to do it all the time as it puts a heavy load on the Converter. Doug


Posted By: Jerry9n on 11/20/09 07:54pm

I asked WFCO about operating the convertor without a battery and Mr. Derrow responded that it could EXCEPT to operate the slide. I might qualify by saying I asked about my specific convertor which I believe is a 55 amp.

This wasn't the original question.

The actual amp draw is the 45 to 60 amps. That TSB is for the CB for the system. I HAVE done the actual amp draw for diagnostics for the LCI pump and that is what it actually pulls. What is your point?? Doug
