gen set not producing 110v power

We have a guardian 7500 watt gas genie in our MH that starts up and runs great but produces no 110v power. I have to shut it down several times until 110 power comes thru MH. It has never let me down down during the $ years I have owned this MH but I am borrowed time I think. Does anyone have any thoughts on what might be causing this issue. I try to exercise the genie once a month when not in winter storage. The genie has 85 hours on it and once it starts powering up it runs great.

    I'm beginning to believe that they all do this, among the older generac's. Even replaced the stator on one when it blew a hole in the windings and with the new one, it still did that.
    As long as it eventually works, just go with it, but would let it warm up a bit before starting the ac's ....etc..
    Do you even have a transfer sw. or just plug into your genset with your shore cord? Either way, it has nothing to do with it, I grant you.
    Just so you know, all particulars on your coach, when making a post, is extremely helpful for getting the best answers.
  • Sounds like oxidation on either the main breaker on the generator or on the transfer switch
  • Since this doesn't happen all the time it sounds more like the transfer switch not connecting than a breaker problem. Next time it happens, go to the transfer case (usually in the same compartment your shore power cable connects) and give it a couple of hard raps to see if it connects. Or better yet, take the cover off the transfer case and use a meter to check whether the generator power is getting to and through the transfer case.
  • Yup, start by turning OFF and back ON the on-generator breakers.
