**If your Capacitor has 5 or more wires protruding from it, this is an AVR, not a capacitor. Please see the generator model page to purchase an AVR or contact us.**
High specification Generator 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.)
ORDERED MY SECOND ONE FROM GG AND RECEIVED IT IN TIME FOR HURRICANE MILTON IN FLORIDA. INSTALLED IN MINUTES AND GENERATOR CAME ON LINE LIKE NEW, 20 YEAR OLD TROY BILT 3800 WATTS.

Plugged it in and the generator produced power immediately, and it was a good price.

much larger than the original one fitted

Generator Capacitor

Done a test to confirm what component was at fault, voltage output was hitting 300v, located the Capacitor on Generator Guru web site, matched up the specifications and ordered the part. Delivery very quick, the part was for a Deisel Generator, part fitted and everything as it should be, please note I could not locate this part anywhere else other than @ Generator Guru. Great service

12 uF Capacitor on 6500 generator (1st generation)
Posted by Eddie Godin on 30th Jun 2022
The part fit well, the generator push little bit more than 120/240 volt again , the governor is swinging with no load. So I need to test it under load to complete the test
