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.

    Recently my generator capacitor went bad. The only place that had it was Generator Guru. Very fast shipping. Installed the capacitor and was up and running in 30 minutes. Great hard to find products and shipping. Thank you guys again.

    Generator runs like new

    The capacitor was a little larger than the originals in size, and was fearful of not being able to replace the generators rear cover, but the end cover was still able to fit over the capacitor, and was able to complete the task with the satisfaction of well done.

    This capacitor fitted and worked perfectly in my Campbell Hausfield generator. The best part is the video on u-tube showing how to diagnose the problem. The wrong size capacitor was shipped first by their mistake and was corrected immediately. Great customer service.
