i baught an 07 aerox with a immobilizer on it but noticed the batter dies stupidly quick like 1 day without starting the bike .. id baught the bike in march and the weather was quite shitty. if i put the immobilizer on it would last days but the battery wouldnt show sighns of like ... like when clicking the electric start it wouldent even make a noise as summer come and things warmed up i noticed i could leave the bike 4 -5 days and then start it perfectly fine off the electric start even if id had the immobilizer on but now weathers got cold and the bikes wont start of the electric start even if ive driven like 10 or more miles turn the engine off then try start it again to be honest i havent got a clue what it is if anyone could help id be very happy because i dont wana buy a new battery to find out the starter motors gone or buy a new starter motor to find out the engine isnt charging the battery if you no what im saying
Get a decent power supply and put it direct to the starter motor, if it spins you know its fine and your problem lies elsewhere, if your battery is more than 2 years old id advise to replace anyway, they are cheap enough. get a decent battery in there and with a multimeter set to voltage , put the leads to the terminals with the bike running , you should be getting a reading of roughly 13.5-14.5 V at about quater throttle,You will then know if its charging. But by the sounds of it you've just got a jammy battery .
