    check if the charging system is working ...with the engine running you should have 14 to 15 volts

    was the NEW battery charged up or tested before you tried it?

    I would guess battery to cable connection is bad. When you put the jumper cable on it you're attaching directly to the cable, not the bad connection. You could test that by disconnecting the cables and attaching the jumper cables to the battery terminals and the cable ends. Might be some corrosion cooties in there.

    I have an occasional problem with mine.I have to short across the starter to get it cranked.I think the problem with mine is the safety switch under the seat.Just haven't had time to check it out.I also had to replace the ignition switch a couple of years ago because it wouldn't start.
    Just because the battery is new doesn't mean it's a good battery.Also check your voltage with and without the engine running and see if it's charging.

    Clean the cables and battery terminals again if that don't do it take the battery back
    If it ain't smokin' it's broken.

    Sounds like the battery could have a bad cell. Have the battery load tested.

    You say it's "new"? Then it's under warranty. Have the dealer figure it out.

    if you are getting a clicking at the starter solenoid then some current is getting to the solenoid which indicates it is probably not a safety switch.

    is the engine seized? can you turn it with a wrench?

    can you check battery voltage drop when you try to crank?

    make sure the ground cable is secureed to good ground and that the engine itself is connected to a good ground, you can test that by putting a jumper cable from the ground post of the battery to the engine block making a good ground and then try to start.
