[meltdown]

Hi, I have rebuilt the six pack. installed a separate line from the raise solenoid directly to the T that feeds the drivers rear set of air bags. I engage the solenoid the air bags get hard ( no leaks) but it only raises about a 1/4". If i put a 20 ton air jack under the frame run it while concurrently powering on the lift solenoid it will lift to full height. I don't notice any binding or popping noises. Take the jack out and engage the lowering solenoid and the coach lowers. Any guidance will be appreciated. Thank You. Brion
