High specification Capacitor.

Generator Guru says: 

It is common for the capacitor on a generator to test as working correctly, but then fail when the higher voltages are applied to it by the alternator. It is advisable to always change your Generator Capacitor if the voltage changes (and the engine is normal speed.) This causes 99% of the problems with the electricity output on brushless generators and can damage your alternator if it completely fails, sending a high voltage through the alternator. This could burn out the windings and result in a very expensive replacement being required.

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 or be damaged 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 has degraded. (Usually found on Chinese built generators.)

    Worked like a charm

    Seldom used generator would not produce electricity. Found the Guru on line and located the correct capacitor for my generator.
    After installation, the generator cranked up and produced electricity immediately. Thanks for the saving of my generator.

    after checking out the video on how test my generator, I ordered the new capacitor from generator guru because were I bought my generator they told me the manufacture could not supply any parts. I was very impressed with the 24 hour delivery. My generator runs like new again.

    Purchased this capacitor knowing it may not solve my problem with my generator ..IT DID. I couldn't believe the speedy delivery LESS THAN 24 HOURS WITH FEDEX.I was blown away. The bonus was that it solved my problem. EXCELLENT OUTCOME.

    Searched around town and no one was able get a replacement voltage regulator. Delivery time was reasonable considering the distance. Had to install connectors to wires. Plugged it in and started generator. All is good. Price was right.
