Customer Question

I have a 2007 210 popular.I have the onan/cummins 2800 w/159 hours.The generator runs great however it will not run the microwave or ac.When the generator is running and i turn on the air conditioning the generator shuts down.A mechanic told me my "power transfer unit" wasnt working properly(i dont know what a ptu is or where) and that i needed to figure out why it isnt working before spending the money on a new one.
