Ninja 400 - left the key in the ignition, battery drained. This morning I tried to jump start with my car. The controls come up but when I press the start button, it gives several clicks and it does not start. Does anybody know what is wrong, if I messed things up? Thanks!
Hi hbucher... Your bikes fine, jump it with the battery removed from the circuit and it should start just fine... Your battery is 100% charged at 12.8 volts and 100% depleted at 11.8 volts. Heres the Kicker - even if you charge your battery back to 12.5 volts, it may not be able to hold its rated amps.
Your dead battery is acting as an energy sink, just remove the negative side off the battery and try jumping again. Attach the Pos + jumper cable to the Positive battery post and the Neg - jumper cable to the foot peg ( Note: Foot peg may not be a good ground ) and have another go - I would attach the Neg - jumper cable to the disconnected battery ground cable my self... the battery wont off-gas while disconnected.
Bet it fires right up..
Your bike battery is not a deep cycle battery, it was not meant to be fully discharged, which is destructive to the battery - hopefully you caught it quick enough... if not get a new Lithium-Ion battery, time out circuits aren't new to cars know idea why they don't employ them in bikes to prevent just this scenario...
