[hypoxia]

One of my very good friends brought his cousin who just got certification for working on RVs - he completely understood the Valid system. Even though my engine batteries are done and the coach batteries nearly done (2 8Ds in hand, 6 on the way), we were able to trouble shoot the Valid 5 pack for the back. I have a bad solenoid for the right raise. So in a week or so we should be able to get it up and then see if any of the bags of bad... Thanks for everyone's input. I will keep you apprised...

I'm curious, is it a 5 pack or 6 pack?  I have not seen a 5 pack.  Also, is the solenoid bad or is the coil on the solenoid bad?  I think you will find the coil to be a Hydraforce 4301512 which are readily available, I carry spares of them.  You can check resistance through them or just move the coil from one valve to the next.  You may be interested in this thread about the 6 pack valves.
