Anyone have cold solder joint problems with their Kokusan ignitions?

Hi All,

Recently while riding my 2004 FE550E in Washington my head light quit working, much to my utter dismay. It actually had started acting up just a bit a month before, but, I thought it was the on off switch that was to blame, as I don't use my head light 99% of the time. It's usually got a piece of card board with duct tape over it to keep it from getting broken.

Anyway, it would stop working, and if I got on it kind of hard it would start working again. So I thought it was just a loose/or corroded connection. (turns out that was the case but not where I thought) So, I pulled the tank off checked all the connections and put it back together and it worked, for a few hours anyway. Then it would only work if I pulled in the clutch and revved it hard, and then only for a moment.

After getting back home I broke out the fluke multi meter and read the charging/lighting coils per the manual and both checked open, not good........... I pulled the stator off and with careful examination I found that one of the connections ( there are several) did not look like the others, ie. no blob of solder. I hooked the fluke meter back up again and shunted across the suspected buss with a screw driver and WA-LA good readings.

Being that I don't have a whole lot of experience soldering such small things, I took to work and showed it to one of our instrument techs,Arturo,who does have this experience. He told me NO PROBLEM, and had it solidly soldered up in about 5 minutes. I asked him if felt that the connection had melted off, but, Arturo felt it was a workmanship quality problem and not a component problem. Otherwise known as a cold solder joint. I had originally thought that the connection might have failed due to high heat as this was the first time I had used the light, and tail light at the same time, and had used them for quite a few hours of low speed trail riding.

So, for those of you with Kokusan ignition, it might be a good idea to check these solder joints the next time you have the ignition cover off. I have heard of one or two other similar problems with the Kokusan ignitions, but, overall they seem to be performing very well. Any decent electronics person can re-solder a suspected cold solder joint in a jiffy.
 
I Had a bad solder joint in the ignition stator coil what started as a rare misfire ended as
dead engine as luck would hold it I was not too far from the truck but I had too be towed back by a Honda :oops: nobody was there too see it :thumb: since the stator was
rewound I don't know who did it, when I tested the circuit on the bike it was open
soon as unscrewed stator I had continuity, after some persuasion test reveled a bad
solder joint.as DaleEO sad fixing it is easy

so long VIKING
 
also had a headlight issue. my main mechanic dude buzzard helped me sort it out and it was the cold solder joint on the yellow wire on the stator.
THANX BUZZARD and DALE
the cheese
