Slideout Issues

[Kemomac]

When opening this spring, pushing slideout "out" produced a clicking at the motor relay but no movement. I figured my battery was low then even though it had been on maintenance charge all winter, so I connected my portable battery pack to the battery with same result no change. So I connected my running vehicle to the battery with booster cables to make sure I had enough power and still same result, only clicking at motor relay.

I then climbed under trailer to the hydralic pump/motor location where I first confirmed 12vdc from trailer battery and all connection were clean and tight and i then connected the battery pack to the main relay incoming wire +/- posts and put a jumper from + to the out spade on the relay which drove the two slideout out into position. Problem solved for the time being.

Now preparing to close in a few weeks and same situation exists, clicking at relay when switch is pressed.

What I have done, I took the hydralic/motor assembly home on the workbench, took the motor apart, cleaned the armature, checked bearings, checking wiring, greased pump gears, reassembled and changed and topped up to proper slideout out position fluid level and tested system in both directions with battery pack and had good fluid flow in both directions when applying power to in or out spade.

I reassembled and reinstalled and correctly connected all wiring, result was the same problem still existed then.

Now, I have tested the interior switch, I have almost 13vdc on the main wire(center spade of switch) and read same voltage from main wire to either of the in(green) or out(white/black) wire. I hear the relay click below the floor when pressing switch in or out, no movement of slides. So the switch is good.

I believe that by having driven the slides out with battery pack connected on relay mains(and trailer battery still connected) and applying power from there to the out spade which pulled in the relay and powered motor to run, that it proves the switching relay is good!

I had tested for voltage from trailer battery at relay before applying battery pack and did have over 12vdc but obviously couldn't test current capacity.

So, other than climbing under the trailer and boosting system with battery pack and jumper wire everything to move slides in or out, what the heck is the problem??

Now I expect to hear its a main trailer battery weak but then why didn't my battery pack or the vehicle being connected to it not work to drive slides?

Ideas? Seems like this isn't the first problem of this kind reported but I don't see a solution posted.

Thanks for any help

It's always helpful if you posted the year, make and model number of your RV.
That way, those that own the same model, can be more helpful.

And here I thought I was being very thorough ��

Added it under my name on the post, thanks.

Perhaps I am completely off base here, when you activate the switch what is the voltage at the motors, are they getting correct voltage? I'm thinking you may have excess resistance in the wiring due to corrosion and when you hook up your battery pack it makes up for the voltage drop.

My two cents worth.

Getting 12.4v and relay clicks.

Well Ok that seems correct but I'm not real good with electrical. If it was me I would hook up your battery pack and measure again, see if there is any difference in voltage. One last thought and you may have included this in your 1st posting but the slide works on shore power?
