  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

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?
 
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.
