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 The previous version was outdated and no longer supported.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

Trying to help a friend - quad won't start

Tell me what you guys think...

2001 Polaris Sportsman 400

Was idling, stalled, and now it won't start again.

Brand New spark plug. Battery is good. When testing the spark plug, it sparks only sometimes, not consistent. So we started looking at the ignition coil.

Ignition coil primary resistance is supposed to be 0.3 ohms, it was at 1.5 to 3.0. Secondary resistance is supposed to be 6.3K ohms, it was at 6.0K ohms. I should also add that the coil is receiving 12 volts as measured with the multimeter when the engine is turned over, so I at least know that the power is getting that far.

So the coil resistances are off and it's receiving power from the battery through the CDI, but are the resistances out-of-spec "enough" to cause inconsistent spark like this? What else could be the problem if the coil isn't it?
 
It'll spark the 1st time (sometimes) when you try to start it (either using e-start or pulling the cord). But it never continually sparks while the engine is cranking.

I'm reading up on common problems with this quad - what I'm finding is that the kill system sometimes causes problems because it shorts out or something. A common troubleshooting technique apparently is to disconnect a black wire coming from the CDI, which basically disengages all kill switch functions.

I might have him try that next.
