Generac 5.5 Generator Power Fail

Generac 5.5 mod # Goo57540 in 1995 Gulf Stream Class C / When purchased it hadn't been maintained, carborator had to be replaced, installed new fuel line, filter, changed oil & filter, air filter and the unit ran good on maiden trip powering things inside correctly both on AC & DC - Half way through trip the generator quit while keeping inside cool for dog - running air while absent 1/2 hr. Replaced faulty fuel pump on generator, starts & runs good but I have no power to the inside of mini. I checked the two breaker switches ( continuity ) on the outside (generator) control area above the prime and start switches and they are working correctly. It appears I'm not getting current from gen. to the outside breakers - outside control panel. It worked well before fuel pump went out. Anyone know if there is some type of breaker not visable looking when you look at the outside (generator) control panel that may have tripped I'm unaware of or... thnx much for any help folks

    This question would get more play in our Tech Issues forum, as this generator isn't just in Class C's. Might play still better on SmokStak.com which has a Generac section.

    In addition to breaker(s) on your generator, there will also be breaker(s) on you coach's Load Center. That's where 12VDC Fuses, 120VAC Breakers, possibly an Inverter, and most likely your Converter/Charger are.

    Also, how does your coach shift from shore tie pedestal to generator power? Ours and many others uses an Automatic Transfer Switch. Some, the generator powers an outlet, like the one a shore tie pedestal has, and you unplug from the Pedestal and into that on board Outlet.
  • Yes J-d.....the latter, you plug the AC120 cord into the Gen recpticle close to the Gen itself. I am a newby and hoping I've not damaged anything. Breakers and fuses have been checked and on in coach at converter/inverter control.
  • Is there an outlet on the generator itself? It would be most helpful to determine if there is no output right on the generator...
  • Check for power at the Gen receptacle That will tell you if the problem is at the generator side or house side.
