2003 Gulf Stream with Equlizer Systems jacks question

2003 Gulf Stream Sun Voyager.
This was Dad's coach. But he got sick and passed 2 years ago. I have been storing it in a warehouse now its time to sell it (Brother and I both have 5th wheels).

Anyway, it only has 16,000 miles on it and its in great shape, but Dad had some problems with the jacks before he passed. And with him went some knowledge on how they work.

It has a Manual jack control EQ1702. Can't get them anymore. I did find a 2086 panel. Wiring in the limited documents I can find looks the same. Has anybody switched these panels?

But we don't know what "correct operation" is
Does the hydraulic motor come on when power is turned on to the panel? or only when Up, Down or retract all is pressed?

I also have a feeling he had to switch over to manual power (jack handle he installed on side of pump) when he had the jack problem. I have read "turn the screws clockwise until they stop to allow the jacks to retract". But how to you turn this screw back to original position? Is it CCW until they stop?

I know there was a lot of these systems installed, sure hope someone remembers how they work.

    The most important thing I have found with this system is your batteries, they must be fully charged or the system will not work. It seems to only turn on and off.

    If wired in series, if the last switch in the line "opened" the other 3 switches could be active, but the signal would never make it to the panel.

    In parallel, ANY negative output (jack down signal) would make it to the 1 terminal (pressure switch) on the panel giving you a warning.

    Also, if changing anything like this I would advise making good notes, and packaging it into the space behind the panel so next owner will know what was done.

    Your right. The switches are NC contacts when jack are not up.

    I would think all you have to do wire the switches in series to get the pressure switch input. You would not know for sure with the pressure switch. Which jack had failed.

    Green light comes on, but nothing works. pressing buttons does nothing. only button that works is the one/off.

    But slides work. (slides use same pump as jacks).

    I did find a 2086 panel, and I now know how to modify the system so I can use the 2086 panel :). It will be working in a couple days (as soon as I get time).

    Really my question was about operation, and what to expect.

    I finally got a hold of someone at Equalizer systems today:

    With the 1702 manual panel (was only used by Gulf Stream?), it uses a leg switch on each jack to tell the panel that the jacks are down. (you can see this in the pinout shown in ES documents)

    with the 2086 manual panel, it uses a pressure switch that sends a signal to 1 input to tell the panel that the jacks are down. The online documentation does not show this difference.(document shows 1 leg switch for each jack).

    Also when you first power on the 2086 panel (or turn on the engine key) the pump will run for a couple seconds to raise pressure to the switch so the panel knows if jacks are down or not.

    Neither the 1702 or 2086 panel is available from ES.

    If you have either panel and it goes bad, the only official path Equalizer systems has is to upgrade to the Auto level, for just under $1K.

    Thanks for the help everyone.

    I have called Equalizer Systems and they seem good to work with, providing help over the phone. But I would read the manual first. All their manuals seem to be posted on their website.
