Only 1 plug on generator is working

Do normal maintenance first, like oil, oil filter and air filter and then let it firts warm up before applying a load.

motor humming -- replace the start/run capacitor
no noise at all --- press the thermal overload button or replace the thermal overload switch

Not enough information. What kind of blower?, Leaf, snow? Does it use gasoline? What brand is it? This information is needed to look it up. The model number you supplied returned no results.

Look for the spark plug wire which usually comes out from the recoil shoud and follow it to the spark plug

Refer to my other comments that I made regarding your snow blower.

Change the coil at the magneto that generates the high voltage to the spark plug

if no power on the plugs check for the cercuit breaker fuses and check for your load why it is tripping the circuit breaker the unit sbould not be overloaded

Is your generator wired in to an automatic switchover in the motorhome, or do you have external plug in on face of generator, or near it. The power from the generator needs to be attached one way or another to the motorhome. It may be as simple as plugging the cord from motorhome into it, depending on what set-up you have.

you do not need a manual as long as u comunicate with me...
1- check your wireing...anything cutt off reconnect it..
2- check brushes...if broke or anything...replacem...
3- check AVR card...if blown out replace it....
4- if 1,2 and 3 didn't work contact me,...

don't hesitate to write to me for further information:

It's very possible that the cord is bad (shorted) causing a fault on the generator. I don't think it's fried or anything. Probably just tripped something. Give it a good look over.
