Generator Guru says: 

The Capacitor is essential to your Generator producing electricity. It is required to excite the Alternator windings and reduce voltage surges. Capacitors should last the lifetime of the generator, but can burn out if any of the following occur: 

  • Generator user has tried to draw more power than the Generator can produce.
  • A surge has happened on equipment and the capacitor has blown to protect the Alternator.
  • The Capacitor is made of Paper cells and the paper has degraded. (Usually pre 1998 generators.)
  • The Alternator has got damp and electricity has surged across the windings. (Dry out before running.) 

 NOTE: Do not use this type of Generator with sensitive equipment (Computers, LCD TV, Caravan Charging systems and anything with a computer chip) unless you have an in-line "Surge Protector." These generators are designed to run power tools and the electricity output is not controlled. This can result in damaging your equipment.

    Generator parts that work.

    I looked online for a video that showed me how to fix a generator. I have one, but didn't know anything about them except how to start them. I ran across The generator guru video that showed me the two different types of generators and what to look for when they don't work. I ordered the part I needed and started up the generator and presto, it worked like a charm. These people know their stuff. Works great. Thank You Generator Guru.

    Generator stopped producing 120 volts 4 years ago it was only making 70 volts.Did some research found the Generator Guru website ordered a new capacitor now the Generator is producing 120 volts.
    THANKS Generator Guru.
