My faith in Generac is slowly but surely tumbling...

Brand new Generac Quietpack 75

After replacing the previous generator with a brand new one, it pushes power to all 120V appliances but will not power anything else. I plug into shore power and everything works just fine. The generator was installed 1 day ago and should, in theory, work fine. Any ideas?

So far I have:

Checked all sockets for voltage, they are all receiving
Checked total watts to ensure generator was not over capacity
Checked all equipment plugged into shore power
Tried adjusting the voltage regulator

What is the "anything else" that is not being powered by the generator? It's quite unclear what your problem actually is.

My apologies for not being clear:

Vehicle is a mobile cafe powered by a Generac 75, recently installed (48 hours ago). The "anything else" is all 240V equipment, such as the espresso machine. Upon installation by an authorized Generac dealer, the generator will not generate 240V. Perhaps it was wired improperly? These generators may be installed to run only at 120V or 120/240.

Steps Taken to Diagnose:

Using a voltage meter, checked output from generator. Measure 120V.
Checked all sockets, including 240V, measured only 120V.
Checked voltage regulator and sensor, working.
Equipment requiring 20A, 240V not turning on.

Plugged in shore power and using a voltage meter, measured 240V.
Checked all sockets and received both 120V and 240V in their respective outlets. All equipment functions normally.

most rv gens are 120 vac you have to reconnect them for 240 vac. to do this you need to change some wires on the circit breaker and on the neutral post.
Your connections now should be 22, 44 on neutral post and 11, 33 going to c.b. this will give you 120 on both legs. To get 240 output use 11 and 44 to c.b. and 22, 33 to neutral post.

Then call him back. If you bought and paid for a unit that is 120/240v then that is what you should have. If you go in trying to re-tap the gen. and it blows then it is on you. Let them do it or find out what is going on. That way you do not risk voiding the warranty.

A different Generac dealer fixed it. Simply put, the wiring was wrong. Wire 11 was wired to where 33 should have been and vice versa. Quite odd but fixed. However, the new problem just arose 3 days after having that done:

Engine Will Crank, Won't Start
Checked Fuel, Checked Oil, but I have a question about this. Near the Starter Contractor is another Fill Cap for oil. No dipstick. Not sure what this is as the Manual does not state a Fill Cap being here. When removed, it looks empty.
