[QUOTE="R. Pierce Butler"] jlpridge [email][/email] wrote in - I recently (last week) purchased this motorcycle. IT runs well with a fully charged battery. However after I ride it for awhile and the park overnight it does not seem to want to run well at all. In fact the battery dies and the bike will not even start. I do not leave th key on or in it overnight. When I jump start it the bike starts up and as soon as I disconnect the jumper cables it dies. I do not want t start blindly replacing stuff. Please help. I do like this bike. - Something is draining the battery or the battery is bad. I have seen batteries discharge themselves. Charge them up and they pass th current draw test (barely). Let them sit and they are dead in 8 hours. T test for this, charge the battery and leave it disconnected from the bik and the charger overnight. Connect it to the bike in the morning. If th bike starts OK then the battery is probably good. If something is draining the battery, then you have to track it down. It could be a bad rectifier/regulator, switch or ????. pierce[/QUOTE] The battery is brand new as of monday, so now I am going to star testing stuff. I will get a multimeter today to start on it
