So I got my stock '04 Superhawk back in June. Great bike. All stock, needed a tune up, which I took care of. Also went ahead and put a new OEM battery in it and did the R/R upgrade. Everything good to go. Now has almost 19K miles on it.

Tonight I had been riding about an hour. Pulled into gas station to fill up before heading home. Wouldn't crank back up. Put a jump box on it, cranked up, rode home.

Battery is overly discharged, reading 11.7v. Jumped it, checked it and it was at 11.66v. So I pulled the R/R off, and it was hotter than hell. I put the old one back on (saved it just in case), and it read 12.75v. That was as high as it would go. When I unhooked that one it was pretty warm as well.

Checked stator continuity to ground, negative. Checked my connectors and everything looked fine and was tight when I pulled them apart.

So… where to from here? Think I am the victim of bad R/R's? Further test on stator? Possible issue elsewhere?

 

What specific model R/R did you upgrade to?

 

Shindengen FH012AA. Believe it's from a Yamaha, can't find the receipt right now but I believe it's for a R1. It was new.

If it were me I think I'd first verify the stator meets spec per the shop manual. Also verify no signs of weak, loose or corroded connectors. I'd also be curious how each rr behaves after the battery has sat on a charger for a day. Link to searchable PDF of manual above.

 

Well, I got up this morning and checked it with a fully charged battery. Battery showed 12.83v, hooked everything back up with the R1 r/r, checked it. Charging at a minimum 13.57v, voltage went up with RPM's. So it appears to be normal. My only thought is that there was moisture in a connection or one of the connectors appeared secure but was not actually transmitting current. I'm going to go back and check connectors when I get home.

 

SO rechecked it tonight when I got home. Cleaned all connectors, using a charged battery and I cranked it up. No charging from the mofset. Checked connections, tried several times- nada. Wired up old r/r- worked fine. Ran it for a while to check. Rewired it using correct connectors and old plug and set it back in place. Still working fine. I have no idea except that possibly a bad connection messed up the mofset? Or I got a bad one?

 

Could have been either, don't know how you'd prove one over the other.

 

Not sure either. Maybe its possible a bad connection caused that unit to burn out or work intermittently. I know I don't want to be stuck on the side of the road again.
