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 The previous version was outdated and no longer supported.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

Need Some Electrical Troubleshooting Help

AA Class
On a moto vacation... 449 running fine, then starts coughing and dies. After some troubleshooting we find I have no charging. 20 miles from base camp, and two KTM batteries get me home...so the system is drawing all power from the battery with zilch going in.

Multimeter confirms zero impact on volts running or off.

So I am down to voltage regulator and stator right?

I do have the repair manual. It states that I should see .8 ohms from the main harness feeding the regulator/rectifier. Are there some other easy ways to narrow down if I am looking at a bad stator or rectifier?

The stator is over $400! Yikes!

I am hopeful with enough calling around I can find them both in stock and get them fedexed and rolling. Any tips?
 
Ok, got into the wire harnesses.

I am using the factory shop manual page M.30

Generator stator windings resistance (1) inspection
Disconnect the stator coil connector from the wiring and measure resistance with a meter.
1) Check that across the terminals of the connector (2), the value is about 0.8.
If resistance is outside the specified limits, replace the complete generator.

I am looking at the blue and yellow blue. Is that the right wire combo to check?

On the wiring diagram, it is the one with the big #2 on it.

There is some series of testing on the voltage (I guess in A/C) across the three yellow pins. Anyone got a quick guide on that? As soon as I charged the battery, the bike fires right up and idles perfectly...just have no charging.

This blows!

More info. Stator seems on.

I checked all phases off and on. Resistance is .8 ohms on all three phases. Running I am getting AC voltage in the 30's at idle and up to 80 with revs.

So am I down to voltage regulator?
 
More info. Checked diode both ways. I am getting out of limits on either the positive or neg side (cant really tell which). Other side tests fine. I have a cheap multi, so no tone, but I get a reading of OL on one side and 550ish on the other (on all three phases).

So 98% sure I am down to regulator / rectifier. Now I just need to find one in the US someplace...
 
I just called Bills about some parts and they seem to stock quite a bit of stuff. Give them a call.
 
I gave him the voltage regulator off my 511 (Devil). None available and he needed one asap. Not something I would normally do, last person who touched devil had the fear of God placed on them. :censored:

I was pecking on my tablet - wanted to properly thank Tinkin and Zipty - seriously - class A guys!

So...I wonder how much faster I will be now!

I may call Husky NA. When my bike was brand new, I had a misrouted wire loom that had rubbed and grounded out and shorted the electrical system. Dealer fixed it and Husky picked up the tab. Six months later, the regulator goes out...I believe the two are indeed connected.

I cannot image a regulator going out on a one year old bike.

Tinkin - you rock. Thanks a ton! Danny ordered a new regulator and it will be on your bike by the weekend.
