John Deere lawn tractor issue

    I have an early 90's JD 265 lawn tractor with the 17hp vertical shaft Kawasaki. I put in a new ignition switch and it started right up and runs like new. I don't have a battery, so I use my Black and Decker jump box to crank it.

    Here's the problem: The engine shuts down if you turn off the jump box. If you leave the jump box connected and turned on, the engine will run great. I'm stumped, but maybe it's possible the motor is not making it's own spark electricity. Any ideas?

    My dad has the exact same mower and has had that same problem. The fix was simple, just clean the battery terminals and replace the cables. Obviously a properly charged battery helps too.

    Ok, I'll give it a try. Thanks. It's the strangest thing. When it first happened, I went crossed eyed. LOL I expect it to just stay running.

    I have a complete extra engine if I need to rob parts.

    You need a battery in the thing even if it doesent hold a charge it will complete the circuit and keep the voltage needed running through so it will run
