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.)

    I found the part I was looking for on the first try. After installing part I was able to get the generator running back to peak performance. Thanks Generator Guru. Dave

    Better than my OEM Capacitor !

    Posted by Dave G. on 26th Oct 2017

    Very happy with the part I ordered from Generator Guru! I ordered a capacitor for my generator. The part fit perfectly-just plug & play, and my generator now produces more voltage than it did when it was new. Was producing 116 VAC, with new capacitor it produces 240 VAC. Would highly recommend ordering from Generator Guru.
