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 The previous version was outdated and no longer supported.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

Suddenly dead, no power to speedo/starter/ignition

Husqvarna
AA Class
Took the bike and the laptop out to finally sort out the bottom end tuning, took it for 1 lap and then fired up iBeat to tweak the No1 values. All good there, put laptop away and set it aside. Jumped back on the bike.... thats weird, the keys still on but there's no power to the speedo. Cycled it off and on a few times, nothing. Hit the starter button, nothing. The tail light and that small bulb in the headlight are on, but nothing to the ignition system. Tried bump starting it, nope. Checked the 2 fuses on the right side of the bike, 1 looked a bit dicky. Replaced it still nothing. Pulled the tank and had a look around, couldn't see anything wrong. Battery reads 13.2v even when key is turned on

I did replace the resistor that controls the reserve fuel light the other day, its possible I nicked a wire with the scalpel so that'll be my first look. Aside from that, where else should I be looking or testing?
 
Ok, so the manual mentions there are 3 fuses, and they look completely different. Hmmm maybe I should check that out...

After I pulled the side cover off I got a better look, sure enough only 2 fuse holders and they were completely different. I peeled back some layers of tape and sure enough I found entirely new levels of stupid. So at some point a previous owner thought it might be a good idea to cut off all the OEM fuse holders, then twist and tape 2 of their own dodgy fuse holders in place instead. That exercise must have been too much effort for him, so he didn't even bother with a fuse on the last one which controls the ignition. "Yep i'll just twist those 2 wires together which are supposed to have a 20A fuse between them, then slap some tape on it. :thumbsup: I'm sure that'll last for years without any issue whatsoever" :banghead::banghead::banghead::banghead:
 
Oh, that sucks. Some people should never be allowed to touch a wire. I would guess something was causing the fuse to blow repeatedly, so the tweaker solution was the thing. Now you might as well go over the whole loom and see what else is screwed up. Hope there's no permanent damage.
 
I hope you can get it going again - and there's no expensive damage. Sometimes certain fuses are prone to overheating. Never had that problem on a dirt bike, but on a street bike I have replaced the main fuse with a MAXI fuse and holder with the same amp rating. The larger fuse will still blow under the same conditions, but it's less likely to overheat.
 
I would kind of understand if that were the case, but the fact he twisted n taped and completely left out any fuse whatsoever on the 20A circuit indicates severe retardation over any sort of ingenious thinking. If a fuse keeps blowing you find the cause and fix it, not just twist the wires together. If it keeps blowing while you are trying to find the problem you use a circuit breaker

I've resoldered everything properly and applied heatshrink. Had to make my own little fuse holder for the 20A circuit but its insulated and sturdy. Bike fired up just fine so it seems to be ok
 
One house I bought was the same... Pennies stuffed in the screw in fuse outlets. When I moved in every appliance blew up and every electric switch in the house started to smoke And that was life in the Columbia River Gorge in the '80s. :rolleyes:
 
The only forgivable explanation is a trail-side fix. But even that should have been fixed before the next ride - or at least disclosed during the sale.

+1 on taking a more thorough look at the whole bike (not just the loom). If there are any remaining "previous owner secrets" (POS) lurking in there, you want to find them in the garage, not the woods.
