Update - Checked all the lines leading to the centerpoint airbag, and could not see anything wrong. Took the air chuck and moved it every which way and could not get it to take air. Then did what a number of people on this site told me, change the air valve. Working just fine after the change of valve stem. I would never have thought of that - So thanks to all for the info, turned out to be a simple fix. Track lighting at least for now is working every time. So will wait until next no go, then bend the tabs.
Thanks!!!!
