Onan microlite 4000 not doing anything

Look for a fuse.... it is always a fuse.

So when I bought my RV the generator would crank right up and work fine, it was serviced and has all new parts on it.

After that it would turn but not start and then when I got to my destination when I tried to crank it it didn't even turn over. What could this be?? I have a feeling it's something simple but have no idea where to start. I literally have ZERO experience with generators. Batteries are charged and the fuse on the gen looks fine. Any ideas?

If it does not crank or turn over when you press the start button. I would first check all the battery connections and make sure the are clean and tight. What is your resting voltage on the battery?

Battery's are reading fully charged, my gas tank is full I was aware of that feature,
And like when I push the start button on the generator it self nothing happens, no turn over, no clicking, nothing. Before that it would continually turn over but not run, but was running fine not even a week ago. No idea what the problem is.

Check your battery with a voltmeter I would not trust the battery lights on the monitor. Post what your voltage reading is here. If you don't want to check each connection for corrosion or tightness back your car up to the genset and jumper the car battery directly to the starter and ground. If it starts the problem is either your battery or the connections from the battery to the genset.

When that happened to mine, it was a bad connection of the negative cable on the house battery. However, it could be a bad connection anywhere on the electrical path. Check all of the connections, especially, the ground connections to the frame of the MH.

Usually motorhomes are set up so that if you're low on gas, maybe less than a quarter tank or so, the generator won't run. (This is done by having the generator gas pickup tube stop somewhere above the bottom of the gas tank). That way, you can't run out of gas and strand yourself by running the generator.

It should still crank even if it's not getting gas. (If you mean it cranks but doesn't fire, that's still turning over; the motorhead terminology can be a bit confusing if you're not used to it. Turning over just means the engine crankshaft rotates somehow.) Slow or no cranking would suggest that the house battery is discharged or there's a poor connection somewhere between it and the generator (usually it's connected to the house battery and not the chassis battery). This could be either a positive connection or a ground connection. There are other possible causes, but those would be the first ones to check.
