1988 , 1100 ? Anyway, when the bike is running did you run a volt meter on the battery. Should read around 14. something volts. If it reads only the battery like 12.4 volts then most likely the stator is gone. Now what kind of bike was that again?
Put a battery charger on it.
Use a low rate charger only, 1 amp or less.
It is likely that your battery is losing power when it sits for extended periods. You should periodically go crank your motorcycle, or change the battery.
12V
it recharges the battery automatically, but it will only recharge the battery if the bike is running.
You can use, for example, a Yuasa YTZ14S motorcycle battery.
Stator: This is the device that acts as an alternator. It delivers a charge to your battery to keep up. Most older bikes have to have the engine removed to change this.
Under the seat. Remove the the bolts holding the seats and you get to the battery.
The battery on almost all MOTORCYCLES is under the seat, It is on your Honda MOTORCYCLE too, call A Honda dealer, ask for service, they will be happy to tell you how to get to it.,,,,,Good luck, Jamison.
Just connect the battery to the motorcycle battery cables with jumper cables and then start it.
AS YOUR SITTING ON THE MOTORCYCLE, IT IS BEHIND THE R.H. SIDE COVER
you will have to install a plug onto the battery terminals
