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 The previous version was outdated and no longer supported.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

2013 TXC 310. Wiring Loom Issues ?

As above 2013 TXC 310 , 5 Hours. Won't start !

Have only 4.6v at Fuel Pump when cranking, Relay / Fuse etc... all good. (12v coming from Relay).

Seems like 0v at Stick Coil (Difficult to measure). Checked / cleaned all connectors etc...

Any Ideas ? Seems like a fault in the Loom ? Or a faulty ECU ?

Looks like the wiring under the Tank, was designed / fitted by a small child !

Anyone else had an issue ?
 
Sorry, had to run out door for work.

Mine ran great for couple hours, then every once in while wouldn't fire. Let it sit and came back later and would start.

Was out riding mine and stalled and wouldn't start. Several attempts/no go.

I checked coil stick and was ok. Made sure that fuel pump was humming at start. Check all wiring under radiator braces to see if heat shorted one out. Checked fuses and etc.... then went and got another plug and no spark. Me I thought I had a b bad coil stick but I checked resistance and was ok.

My thoughts were the ecu or sheared flywheel key. Mine was still under warranty so took it back. I spent about half day there. We switched, ecu, stator, coil stick, even check flywheel key and regulator.

Come to find out, we put my stock ecu back on and it sparked for a little bit, then no spark again. So we knew it had to be around the ecu. When they put the wiring harness together and push the wire connectors into the main connector that plugs into ecu. Someone failed to push it in far enough so it clicked and held in connector. So wire back out under vibration or reconnecting ecu. It is really hard to tell if it is clicked in.
So unplug your ecu and pull the connector out in open real good. Slightly tug on each wire to see if one pulls out
/kinda loose in there or push in on them. Then reconnect it to ecu while it is out of its holder. Crank it over to see if it sparks.

Halls told me that these bikes are bullet proof and alot of guys ran them last fall. Even changed the taper on flywheel for shearing key issue. We had a heck of time just getting flywheel off with puller. So we knew it was something simple. They have had no issues with flywheel, ecu, regulator, stator, coil stick, etc......

I went to a local yamaha/suzuki/honda dealer next week and was talking to their mechanic, while buying oil. He said they run into the same issues of wire not snapped into their connectors. He said when a new bike comes back. First thing he does is pulls the harness connections out and makes sure all the wires are snapped in.

Also, if you put an hour meter wrapped around coil stick make sure it isn't pulling on the two wires. Wrap it around the base 4 times and use black electrical tape wrapped over it.

I am real careful to make sure when I pull tank that the fuel line doesn't pull on wires.

Hope this helps but has to be simple.
 
Thanks for a great reply. My bike is similar story , Ran great for 4 hours, then developed a "stumble" like fuel starvation, then no start .

Today checked loom and voltages etc... looks like a faulty ECU ? Going to dealer Thursday and will swap parts etc... Bike is under warranty.

Will post our findings , but I will just double check that ECU plug again !
 
Quick update . Took bike back to Dealer today (Husky Sport in UK - Great Service as always !).

Problem was the ECU ! Replaced and reflashed from another bike , all OK .

Thanks for these posts as I have been experiencing a very frustrating intermittent fault.
My bike starts well and idles perfectly.
Sometimes I can be riding and I get a slight fluctuation in power before the engine shuts down completely and when this happens the engine will not start for at least 30 minutes, sometimes a litle bit more.
No matter how much I try...IT WONT START and/or run. I have pushed this bike so many times to get back to car or home, as I said "VERY FRUSTRATING" My local Husky dealer has been fantastic. They have inspected the enitire fuel system and recently pulled all electric components: Coil/stator/cdi to be sent to an engineering group and tested all elec components on a jig at temperature to make sure resistance was established and iliminated from causing the problem. Report came back from the engineering group with a clean bill of health - no problems. All elec items placed back on bike and while riding same issue occured.

Some rides, the bike will be faultless and others it will fail, there seems to be no rhyme or reason to it.

Does this sound familiar to you..?
 
My ECU went bad on my 2013 TXC 310R as well (among other things). Dealer grabbed one of another bike and it started right up. Only cost me a few hundred dollars :mad:
