Does anybody know if the 2001 gtx di has an alternator to recharge the battery when it is low. I keep getting a "Maint 12V" light on my ski lately when I start it up. It beeps for 3 or 4 times while riding, and eventually stops. Sometimes it only beeps when starting and stops instantly. i am assuming the battery is low and after riding it stops flashing "Maint 12V". Can anyone answer if the ski recharges automatically or do I need to pull the battery and re-charge it? The battery is a wet cell, about 2 yrs old. Probably not holding good charge anymore. Thanks for your help--I am new to this site.
