I Bought a 96 cbr 1000f a few months ago. i was on a ride one day and my bike stalled and wouldn't start again. After i found out it was the r/r i bought an aftermarket one. about a month later it happened again with the aftermarket one. So i tested everything on the bike and everything seemed to check out besides r/r. I took apart all the electrical connections and cleaned them and put di-electric grease in all connections. I bought another r/r and once it was installed it worked great. Now today i go to start the bike ( i always check to see if its charging before i ride) and today it was not charging. Why do i keep burning out r/r's. What can i check next, i am getting really frustrated with this bike.

 

Welcome to the forum.

If its getting the proper voltage when running, I personally would be thinking that the battery is old and perhaps calcified causing a short across the plates.
If there were a major short that is cooking the R/R I wouldn't think you'd be able to get a weeks worth of riding. What is the voltage of the battery at rest, disconnected, over night?
That's just my thoughts.

 

FYI, most aftermarket R/R's are worthless junk. Bite the bullet and buy a Honda regulator from the dealer, or if you're up to a little wiring rework, head over to Roadster Cycle and see about fitting a Shindengen FH020AA or a SH847.

 

Hi there, as another user suggested you should check the voltage across the battery with the engine running to make sure it's within range, about ~14 volts with the alternator running, give or take. Also, you should remove the battery from the motorcycle and charge it fully with an external charger to check if it takes a full charge. Visually inspect the battery, are the electrodes green or orange? Is there adequate fluid in the cells? If it's an old lead acid type battery like mine there may be signs it needs replacing. Not starting the bike or holding charge are obvious ones. Or if it's a new battery, is the ampage too high? That would fry a regulator.

Once you've eliminated those basic possibilities, you should be looking for a dead short. It could be a corroded bulb housing, corroded wire in the loom that only make contact when you turn the head, or perhaps an intermittent short in the alternator.

I've had similar problems myself with older bikes in the past, it's almost always a short that only happens under certain conditions, like making a hard right for example, or a crappy battery.

Hope this helps.

 

Hi Guys,

Thanks for all the help. Afyer buying a new OEM R/R my issues was solved!

 

Thanks for posting up the solution. You never know who in the world it might help.
