Hyosung dies, blows fuses

[sapperj]

have uploaded... dont know where it went tho lol

I can see it, the one marked fuse box is the one that blows I guess. Not a lot I can see there that would cause it, especially since it happens with the kill switch or the key. Unplug the reg and go for a ride, see what happens when you turn it off then.

Trial and error... Sweet man. Back later. Just have to put it all back togeather first ffs... $130 for a new stator, $90 for the regulator. Might have to bite the bullet and replace both sein as the alternator/ magneto/ stator is down on one phaze anyway

unpluged the reg, got to the end of the driveway and dead... must be a short somewhere????

What do you mean by dead, just cut out, or won't start again either, or blew the fuse?

Stalled and fuze poped, same as before

But this time is the only time it has done it before you have turned it off right?

[sapperj]

no, did it once on friday when i stopped at a set of lights and turned indicator on... if there is a loose wire in the stator, could be shorting when engine revs drop??? just a thought.

A short in the stator shouldn't draw current out from the battery though. And it just did it when both stator and reg/rect were disconnected anyways. Going from the wiring diagram, that wire from that fuse goes straight to the ignition barrel, for it to blow when you turn the ignition off, it either short to ground somewhere along that wire, or you ignition barrel shorts it to ground, or your reg/rect shorts it.

But since it also happens with the kill switch, it is unlikely to be the ignition barrel. And it still happens when the reg/rect is unpluged, so unlikely to be that. I'd look for potential shorts somewhere along that wire in the loom, likely to be at junctions, or parts where it get hotter.

That all assumes it is a single cause issue, and not a multitude of course, fingers crossed!

So assume I strip the loom out, fault test all wires etc... should I replace stator anyway based on my voltage test results... It may not be related to this particular fault but I know it is down on 1 Phaze, and not sure if rectifier is ok, again based on resistance test... dont want to waste money but I need the bike and intend keeping it for the next few years...

That is one option, another is to clip the multimeter onto the wire, and earth. Then see if you can replicate the failure condition. Another is to bypass the bit of wire you think might be causing the issue. Depends on what your loom is like to get to as to which one might be best.

Just thinking... as this problem primarily occurs when the bike is ridden... might look at the neutral switch and associated wires in and around the gearbox / sprocket area... will post results when I have time to look into this

[TOTO]

what about getting it to an authorised hyosung service agent ?

[ducatilover]

I'd go with Bogan's theory of that little wire, or your ignition barrel is shorting out inside itself somehow?

Maby if I win lotto... plus I have the time to fuk around with it and I enjoy the challenge. Also I like to share this problem here and get other peoples views... and if I fix it, I have learned something and others who may have a similer issue in the future can recall this post and troubleshoot their own problems :-)
