Looking on this forum and RVNet I noted that several folks have
reported a problem on their Jayco/Kodiaks wherein their jacks will
automatically retract when the ignition switch is turned to the on
position. I saw where at least one person fixed this themselves but
I got the feeling that more folks out there might still be having
this problem. Anyway, this has been buggin' me on our 33DS greyhawk ever
since we took delivery in Dec. Well... I finally got it fixed and
here's the story... (kinda lengthy post).

I knew this wasn't acting right so I took it to our local Jayco
dealer. A few days later they called back and said there was no
problem and that it was working just like all the other

they've sold. So I proceeded to show them the instructions in the
PowerGear manual which clearly stated that you had to turn the
ignition to the "on" position and then retract the jacks by pushing
the "retract" button. To their credit, they listened to me and
agreed to pursue it.

First they called PowerGear and over a 2 day period, spent a lot of
time with them on the phone going through and troubleshooting the
entire hydraulic jack system. In the end it was determined that all
the PowerGear stuff was working correctly. However the controller
was receiving a signal that the vehicle was trying to start up and so
it went into the emergency retract mode (jacks up, lights flashing and
alarm beeping). But... of course the engine had not actually been
started, so the PowerGear folks concluded that their system was
receiving a bogus signal.

Next the service guy called Jayco and talked through the problem
with them. He soon learned that Jayco had installed an intermediate
relay in between the Kodiak systems and the PowerGear systems. So then
after some more over-the-phone troubleshooting it was finally
determined that the relay had been wired incorrectly at the Jayco
factory. The fix was to move a connector wire from one relay pin to
another (the correct one this time). BTW, the only detail I got was
that it had been a ground wire connected to the wrong pin. Also I'm
not sure where the relay is physically located but will ask when I
go back. Anyway... now everything works great!

My dealer service guy said they would be contacting their other
Jayco/Kodiak customers now so as to fix this problem in those
coaches

I posted a fix for this in this group several months ago. It was
what Jayco calls a Product Improvement Paper.
