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 The previous version was outdated and no longer supported.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

please could someone help i have purchased a xc 500 1985 husky which was a green lane spec 'non runner'..... its has no spark i am currently changing it to a motorcross spec bike so have took all the lights and swich gear off it.... but i still have no spark and i cannot locate a wiring diagram to look at to see if all my wires are correct...
heres what i know 4x wires out of stat 1xblue to coil , 2x black(1x to coil 1x to chassis earth) and 1x yellow (not sure where to put this.?) i have tried another coil pack which i know works and still no spark please help as i am loosing the will to live........
 
Yellow wire is for the lights. One of the black wires should be for the lights also. Do you have a light blue wire running from the coil to the kill switch? check that wire and your switch first, known for a lot of No Spark problems. I think I might have a wiring diagram somewhere, I will try and find it.
 
Often it is the stator or perhaps the coil. The blue wire when grounded stops the spark. If the blue isn't attached it will run so long as it isn't grounded assuming all of the rest of the stuff works. Pretty much all of the dirt bikes work like this opposite of a normal street bike which puts 12 volts to the coil when you turn it on. Yellow is good for about 35 watts and usually there is a voltage regulator of sorts that goes to then more yellow to light.

You might get this moved to vingage. Maybe someone knows how to use an ohm meter on the stator wires and check that out without swapping a known good one to test.
 
o.k i had a re-think after your advice.. as this was a recently coated frame i re cleaned the frame up the earth point , and re - fitted my coil pack from my 390 OR , and there was a great spark :thumbsup:..... put my original one back on ... no spark :eek: so i think that unit has failed ... any idea's where i can locate other than expensive Eb*y
