Ok I have an update And outcome. Many of you replied with great info and because of your input I started by searching for the Governor I found it on the side of the compressor. I reached down to view the tag and immediately noticed it was loose. After careful examination I discovered one of the 2 bolts holding the governor on , had come out and the other bolt a little loose. I live near a heavy truck parts store and they had the replacement governor in stock. I doubt there was anything wrong with the original but for $17.00 it was already off and so the new went on. I started the coach up and it cycled it built to just under 130 PSI on both gauges then purged. I let it set for a few minutes and it did did not cycle I pressed the brake a few times and the air built back up and purged at the same point as before. I think all is well now but I will service the dryer with a new kit in the near future. Again thanks to all. I hope the post serves to keep reminding us that servicing the air system is a must.
