In case you are still having issues with your hydraulic slide outs here is a simple way to verify you are getting 12VDC signal to both sides of the dual polarity solenoid wall switch input terminals on the solenoid..

With a multi meter place positive lead of meter on either green or Yellow wire where it connects on the solenoid. Put ground lead of meter to SINGLE center post on the solenoid... this is ground

Now have someone press the wall switch inside RV for either IN or OUt motion and observe if you get a good solid 12 volts or higher reading

Now move positive lead of multi meter to Green wire that plugs onto dual polarity solenoid and repeat test above with wall mounted slide switch.

You should see steady and immediate 12 volts DC signal..

If so this will verify that slide switch mounted inside RV is functioning properly
