As stated above the shop did use gages and pulled the system down twice because of the valve leak found after the first time of recharging the system. The replacement switch found has the high side pressure cycling at 325 instead of 350 psi. I would have to have waited two days to get the correct one. But as I stated it is working great so I'm happy they were able to get me back on the road.
