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 The previous version was outdated and no longer supported.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

Fuel pump, battery, or both?

Hey guys,

I was out for a ride last week, and right near the end of it, my bike started backfiring like a machine gun. It would do this for about 30 seconds, loose all power (even at WOT), and the low fuel light would flash on and off, which is strange because that light hasn't worked since I've owned the bike. Then be okay for about 60 seconds and restart the cycle all over again.

I thought at first it was definitely a fuel pump issue, but now when I went out to attempt a quick diagnosis, the battery was almost completely toast. I'm not sure if running it will the pump issue killed the battery, or if the cause of the issue is the battery itself.

When I turned the key on, the fuel pump (I think) clicks away. I took a video of it.


I will bring it to my shop to properly diagnose, but was hoping someone had some input in the meantime, as my shop is a good 2.5hr drive away. Any thoughts?
 
Try another battery, jump it from your car bat.
Yes I know some will say not to but have done hundreds over the years never had a problem.
Some jumper cable clips are so big watch out for grounding on the frame.

Having 4 efi Husky's in our garage and having 3 of them experiencing gremlins like yours, all 3 of them were caused by a bad battery. The ecu need's the proper juice to operate correctly. Replace your battery before doing anything else.

I have these in our '08's and couldn't be happier. I bought the lipo charger also.

yeah... it's your battery or the battery connections (including B+ connections further away from the battery).

to test a battery: charge it up; measure the voltage. wait a while (hour, 10 hours, a day whatever); measure the voltage-> if it's still close then put a load on the battery (a bulb for 5 minutes maybe), stop, and measure the voltage again. btw, the 1st voltage you measure on a good battery might be artificially high- but the rest should be 12.5v maybe. if they battery passes this (and doesn't have a loose plate for example) then you're good to go battery-wise.

the symptoms you describe shouldn't be caused by a bad fuel pump (unless it's shorting out somewhere). sounds more like a bad or lose connection (or yes- a bad battery)
 
That almost sounds like a relay clicking. Deffinately check with a fresh battery. Our bikes need at least 9v to work.
