so after finally buying a well used bike (01 drz400s) and spending the last few months getting it ready for the dirt & road, i was very excited to get back on the saddle after 10 or so years...luckily I got a couple of hours out of it before she died. Otherwise the bike seemed to work good aside from the two new slippery tires, but that is another story...
the speedo display started flashing a few kms from home, but it didnt die. once shut down, there is no juice for lights, or display. voltmeter shows 0 volts (battery removed) and the battery tender is unable to charge it. my uninformed diagnoses is that the bike didnt charge the battery (any number of reasons) and running the battery to ground killed it for good. I suppose the battery could have shorted on its own?
electrical issues scare me, but i'd like to try any simple checks before pushing it to the shop.
I am curious if there are checks I should do before putting a new battery in it? most of the reading i have done suggest performing checks using a good, charged battery, but I would hate to buy and install a second battery if there is an issue with the charging system that could cause harm to the new battery.
just wondering if there are any comments or suggestions. if you are recommending checks please be descriptive, i'm low on experience. cheers
