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 The previous version was outdated and no longer supported.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

1983 XC500: Converting from AC to DC

Hi All. I have an '83 XC500 wired with head and tail lights and a horn for road use. It has the MZ-B ignition fitted which supplies the lights with AC current when the engine's running.

I'd like to install a battery and have it charged up by the ignition and then power the lights and horn from the battery.

How do I do this?

I think the MZ-B already has a regulator to keep the volts down to 12V for the lights etc, but I'll need something in between this 12V supply and the battery to tell it when to charge the battery and when not to (so as not to fry it). I would then feed the lights and horn from the battery.

My electrical knowledge isn't great. Can anyone recommend what I need to install to do this?

Kind regards
Lucien
 
Usually you need to have about 13 to 13.5 volts going back to the battery to charge it above the drain from the lights. You may have to install a rectifier as you seem to already have a regulator built into the MZ-B.
