Since you have a multimeter, you can do this. Measure the voltage on the battery when the bike is not turned on. It should be between
12.3 and 12.5 volts typically. Kick start the bike and then when running, perform the same check. It should show between 13.5 and 14 volts.
If the there is an increase in voltage by 1volt or more, it is likely that the charging system is working. Thus that your replacement battery is
naf. Winter and completely discharging a lead acid battery can kill them. Usually before installing a new battery I make sure it is fully charged
up by putting it on the charger for a day.
