starting problem on a honda

[Tennif Shoe]

My father in law has a 2001 Honda Shadow Spirit 1100. He came home from work and he left the key in the ignition. Somehow it got turned on and now the bike won't start. He has hooked up his battery tender to it and the charging light won't come on (works fine on the car). He has tried jumping the bike off with jumper cables and it didn't work. It doesn't turn over at all right now. He has a no-maintenance battery. Besides battery, what else could it be?

a dead battery WILL NOT be recognized by a battery tender thats why the light wont come on. Are you trying to jump the bike using a car that is TURNED OFF? You can hook the 2 batteries together and that will help equalize your bike battery enough that the battery tender will recognize that you are indeed connecting it to a battery or you can buy a battery charger and charge it for 20 minutes (or barrow one) which will be more than enough for the battery tender to recognzie the battery.

*edit I should mention that the reason a battery tender wont recognize a dead battery is it must see (feel) electricity from the battery. I dont know all the exact properties as in what votage it must see but if it doesnt see it it thinks its not a battery. A charger will try and charge it no matter what it may be. I mean you connect a charger to a metal bar and it will try to charge it.

oh if you hook the two batteries together im not sure the bike will start though it may. I have never tried it with a bike but at work we connect two forklift batteries together for 30 minutes and that gives it enough of a charge for our battery tenders to recognize that its charging a battery.

you know even a seasoned riders can make common mistakes, leaving the key on = bad idea, battery needed to be replaced
