I have fixed this issue but I don't know why the jacks ever worked before. I downloaded an instruction doc from Power Gear that detailed how to install the new 500731 control panel for the jacks. It replaced a number of obsolete panels of which my '98 version would have been one. BTW, I found this doc thru Google search, not the PG website. The PG website doesn't show you how to get these archived docs that I can see. http://support.powergearus.com/techdocs/3010001287.pdf
The dealer put the new control panel in before I picked up the rig in 2010. The jacks worked until the other day.
However, the diagram for the wiring in the doc shows one wire being re-routed from ground to pos on the solenoid. That wire was still to ground. I moved the wire to the pos terminal on the solenoid and "walla", everything works now.
The big question is how the heck did it work before? I did not change anything except clean every darn terminal I could find before I got the PG instructions. And yes I was sure to put them all back on the correct terminals when finished cleaning. I only took one loose at a time and cleaned it, then back on the post with nut.
Am a happy camper again.
Thanks for all the tips and responses.
