LCI slides and jacks malfunctioning

Update to problem: The fluid level did help to pressurize the system enough to where we were able to bring in slides and raise jacks. Once it seemed to work we continued on our trip. Decided to travel to Iowa and made numerous stops setting up and closing up. Eventually, I started hearing a wierd sound when I would press the auto level button. After hearing sound nothing happened. I kept pressing until it went into the leveling of unit. I realized that I still had a problem. We went through Indiana and I made an appt. to have it checked at Lippart. We continued on to Des Moines Iowa and I was abel to set up and depart for my appt. back in Indiana. Set up at camp the night before appt. and everything went well. Next morning as I tried to load onto truck to take to Lippert, the front jacks would not move to raise to truck level. No matter what I did they would not budge. So I called Lippert and Kelly told me a tech would call to guide me through the mechanical process to raise jacks. I decided to jump the batteries from a spare battery and I was abel to raise jacks at that point and got unit to Lippert. They took me right in and through troubeshooting replaced the starter relay and said that was the issue. The contacts had welded together from lack of proper voltage from the batteries. I took it to another technician to check out the rigs electrical and everything checked out but one of the cells might be bad under load. One thing I want to share with everyone is that I have been to Lippert three times for an issue and each time the people there have solved the problem and been very helpful and at no cost to me. Now everything is working well and I will keep an eye on batteries and fluid level. Thanks to Lippert, Bob and Rick for their expertise on the leveling system!
