    The service manual says that the capacitor is to protect the electrical system if the battery becomes disconnected. What are the failure symptoms? I have mine out to check and flip.

    I flipped my capacitor today because I finally got around to it.

    I forgot to reconnect the capacitor and the bike started like it normally does when hot, i.e. reluctantly.

    What does the capacitor do? Is reluctant hot starting a symptom of failure?

    Also, is there an easy bench test for the capacitor?

    A capacitor is like an electrical storage device that is generally used to smooth out the spikes in electrical circuits.

    The value of the capacitor is printed on the case. You can test the resistance of a capacitor using a multimeter, however voltage needs to be applied to the capacitor leads to test actual performance, which sounds easy but it must be removed, and tested on a bench. The voltage and amperage must be generated by a good known value power supply and ideally be the same values being used in the electrical system on the bike.

    In other words, the general thing to go by, either it works, or it doesn't. A failed capacitor will become open in a circuit. A leaky capacitor will not be able to maintain voltage over a given span of time. Heat can affect the performance of a capacitor but is not a guarantee that the capacitor will fail. Over time a capacitor that is subjected to high heat levels will generally become leaky or fail.

    That's why it's best to give it as much air flow as possible.
