I have a 94 F2 and have been going through batteries about every 3 or 4 months. I have had the charging system checked at two different shops and have also checked it myself. It checks out fine. The regulator/rectifier also checks out fine. I can ride it to work, about 10 miles, and everything is fine. If I ever ride for over 50 miles at one time, when I pull it into the garage, a very strong smell is coming from the battery. The next day, the battery is completly dead. It can't be charged and I have to get another battery. Could it still be the regulator/rectifier even though it checks out ok? I think the battery is getting overcharged. What does everyone think?

Thanks for the help,
Gusto.

 

battery is overcharging....its the Regulator/Rectifier...

 

What do you mean by checks out okay?

What was the voltage reading at the battery with the bike at about 4500 RPM???

 

The voltage reading at the battery is a 14.2 at 5000 rpm.

 

It still sounds lik.e the R/R to me. The very same thing was happening to mine earlier this year and a new R/R fixed it right up. How are you testing your R/R? The manual is very specific about the kind of multimeter to use when you test it. Take it to Honda dealer and have them check it for you.

 

eweppley...what kind or reg/rec did you buy? and where? I have been checking mine with my multimeter so I will take it by the Honda shop this weekend and have them check it for me. Thanks.

 

I ordered a new OEMR/R off of ebay. They do hav.e aftermarket ones for F2s with cooling fins on them and you ca.n find deals on them sometimes on ebay. I sort of wis.h I would've gotten one of tho.se. My old one lasted 26,000 miles. The new one should last that long as well...then I'll get a fan.cy finned one.

 

I had same prob it is theR/R. Don't go with the stock one they suck. I got mine from regulatorrectifier.com 80$ I should have spent in the beginning.
