powergear hydraulic levelers right jack not working

I want to thank everyone who responded to my post. I finally had time to look at and find my issue with the right rear jack not working, It turned out to be the wire that goes to the right valve solenoid looks like the spade connector that the wire goes in had corroded off. so that's my issue now. I have the power gear hydraulic leveler system on my coach. looks like I just need to replace the solenoid that slides on to the rod to turn the valve. I hope I can just get that part somewhere. From what I have seen the model I have is 500105E and the powergear website is saying that model is discontinued. so I will be calling them to see if I can at least get the solenoid for that. fingers crossed.Hopefully I will not have to replace the whole unit for just a bad solenoid.
Any one else ever had any issue with wire rot on the solenoid and did you just replace that or did you have to replace the whole valve. or if any one has any input on this that would be great thanks for your time. Mike
