Because I'm bankrupt, my car needs service too and I delay it. I had the battery plugged on the car half an hour as I trying to jump start, the battery remain dead. I also unplugged the headlight to save current but nothing changed so I consider it dead.I was recently jumpstarting a dead battery and it did the same thing...clicking instead of turning over. I let the truck run and left the cables on for ten minutes so the bike battery could get more juice and it finally did start.
On a separate note, is the battery toast or can it be charged? If it's toast, why not go buy a new one? You'll need one anyway.
1) the car is a 1.5 diesel and I had it running when I tried to jump start. (in case diesel makes it even worst)If the battery is bad enough it will drain enough of the supplied voltage so that the ignition system is robbed of enough voltage for reliable starting.
If the bike was put away for TWO years with fuel in the fuel rail / injectors then your injectors are probably plugged with old, bad fuel.
The motorbike charging system can not handle the amperage an auto charging system puts out so you should not have the auto running w/jumper cables hooked up to the motorbike.
2) the fact that nothing changed when I disconnect the headlight means that it will not start with a new battery either, or there is hope?
Thank you all guys from the replies
