• Husqvarna Motorcycles Made In Sweden - About 1988 and older

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 The previous version was outdated and no longer supported.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

I'm trying to hook up the lights on my old WR. There was a rectifier or something in the circuitry that bled off the excess amperage put out by the stator at high revs. I remember the stator would burn up the bulbs the first time the engine speed increased above 4,000rpm or so.

Who remebers what these gadgets are, where to get one, and knows where in the wiring harness it goes?

The stock SEM ignition puts out AC current on the yellow wire. Yes, it will blow the bulbs. You need a voltage regulator which does exactly as you say... bleeds anything above (roughly) 12 volts to ground so the bulbs don't blow. If you just want lights you can leave it AC and all you need is a regulator. They're cheap and any cycle store should be able to hook you up. If they don't know what you're asking for... find another store! You don't need to rectify the current to DC unless you're gonna try to hook up a battery.

Usually the regulator has two wires coming out of it. Yellow from stator to one of the regulator wires, other regulator wire goes on to the headlight switch, through the bulb, to ground.

Typically, the regulator must be cleanly mounted to unpainted frame for a ground, and they ground through the body of the regulator. You MAY get one with a ground wire. No big deal, just run the ground to the coil mounting bolt.
 
one more thing... if you get a voltage regulator with just one wire... no big deal. Just tap that wire in parallel to the yellow, and ground the case of the VR to the frame.
 
Thanks for the help. I thought there might be different types of regulators. Glad to hear any old one will do.
