Hi all,

I apologize in advance if this sounds a bit silly but its the middle of the night and im thinking of any solutions to my problem!

My Reg/Rec is fried and over charging the battery. I can run the bike with the wires from the stator disconnected from it no problem, apart from the battery starting to run down. (I only have a 15 minute run to work and then trickle charge the batt all day)
Ive ordered a new reg/rec but it won't come for a few days and was just wondering if only connecting say 1 of the wires from the stator would reduce the load on the reg/rec and then the battery?

From what ive researched, having the stator wires completly disconnected, apart from the battery going flat does not cause any problems due to no load being pulled from it by the battery charging or from the lights so any voltage is just dumped. Please tell me if otherwise!!


Thanks for any help

it sounded stupid when you wrote it didn't it?

It is a stupid idea dude..won't work.

either take the hit and buy a reg rec, today, from a local shop or put up with waiting for it.

If you can, use a spare battery - lights off and try to be safe.

My '30 had a shagged genny and reg rec - I could just about make it home from work but some times was stranded and pissed off.

fix it properly, no more bodges.

lol i thought so!!

Thanks mate, yeah i do have a reg/rec from an R1 ordered for delivery by end of week so i will wait. haha thought it was worth asking at least just in case!!

You'll easily get 15 minutes without the regulator plugged in, preferably leave the headlights switched off if possible.

Then charge at work, and again when you get home.

Easy.

thanks, yeah thats what i did in the end, just charged it everytime i stopped. got 10 - 12 miles out of it before seriously misfiring.
Got a new reg/rec and battery now and fitted a cpu fan too, so hopefully should be good for a while!

Try slapping some CPU heatsink compound on the back of it.

I think they overheat so blow up, when I was looking at mine I noticed that as the plastic case of the regulator came round to the metal section on the rear and it was very slightly recessed inside ( if that makes any sense ) maybe only 1/2 mm. But maybe just enough to not make a good enough contact with the sub frame so it cant dump the heat.

I dont know if it was the original honda one, I ordered a new one and lobbed the old one in the bin, the new one was flat flush.

ah yeah ill check that today. I used the fan from a nvidia geforce graphics card which is designed to draw heat sideways instead of from beneath it. So i just put it alongside the reg/rec and it seems to be keeping it way more cooler. Its just wired into the rear light circuit so it will stay on with the sidelights etc incase anyone needed to know!

40mm chip fan from Maplin, and a couple of m4 stainless allen cap bolts. The fan needs just a little bit of modding by opening up the screw head inentations. If you used m4 screws with a panhead you could skip that step but it mightn't look as tidy

Then wire into the brake light feed and chassis earth. Easy cheap and cool.







On my Fireblade... which actually did catch fire.



Worked on the cheap pattern regulator and the Honda OE replacement finned part equally well. The fins ae spaced perfectly such that the screws just bite and self-tap. Not overly strong but plenty for what's needed!

Unsure about the effects this has for a roadbike,but on my race bike I remove just one of the wires to stop the excess charge.

Based on when one winding on your alternator gives out - This will give your regulator a harder time, I wouldn't advise it.
