  • 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 The previous version was outdated and no longer supported.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!

FE/FC 15 350 FC relay noise / flat battery ?

Hi,

When the bike is sitting (not running) it sounds like a relay is regularly resetting itself. Anyone else experienced this? Since its started happening the battery is going flat (No surprise).


Any advice on best place to start?

thanks
 
There's 2 ways to switch on the main relay. First by putting the handle bar switch in to run mode and hit the starter button. Second by putting pin 5 of the diagnostic connector under the seat to earth.
I suspect the plug under the seat has moisture in it, either at the diagnostic connector or on the ECU itself. Pull the connectors apart and clean with contact cleaner and blow out.
If that doesn't fix it it is basically to the dealer to hang on the diagnostic tool.
 
Thanks for the info I will take a look this weekend. :)

From memory these problems did start after the first time I washed the bike with the seat off so will check there first. Its bl@@dy annoying as it can flatten the battery in one night if it feels so inclined.
 
I used my air line to blow out the ECU and connectors.

But then I swapped the original ECU out for a Vortex unit. All back together and no more relay noises. :cheers:

Thanks for the pointers
