Thanks Puter. Started her up today to see if all was good. Compressor ran fine. Tested running a little RPM on her and the Cycling is about 5 second run times with some seconds off. But the Air is cooling down just don't have another Fox to compare against. Will definately post the question to the AC forum as well. Thanks for your help. In Idle it stays engaged for long periods and I am see real good temps so I presume I might be OK and that short cyling is expected any type of RPM. Which I can only tell with hood open and not running with air flowing over the condenser.
