Craftsman 917.257740: trouble starting/keeping running.
I have a Craftsman tractor #917.257740 which, when I turn the key, nothing but a single "thunk" sound and the engine does not spin. The lights do work. Put the battery on the charger again for about an hour, same problem.
Checked as many leads/terminals as I could. I did find a wire near the fuse holder which had the insulation rubbed off of it and the wire was exposed. I believe this was causing the problem I was having with the fuse blowing. Everything else looked fine.
With a jumpstart, I was able to get the mower running and mowed nearly my entire yard-which is not large. The engine then died on me and I couldn't get it restarted. Jump started again and it only ran for 2-3 minutes then died again.
To me, this eliminates the starter and solenoid. Once it was started, it would not run for more than a few minutes before it dies. Once that happens, there isn't even enough juice in the battery to light the headlights. So that confuses me. I would think that if my alternator was worthwhile, the mower would run until it ran out of gas even without a battery. However, I DID have a car once that had a perfectly good alternator in it but it would not stay running because the battery was bad.
So, my battery is at O'Reilly Auto right now getting the 1 hour plus charge and load test to determine if it is any good. I know for sure it is a 2007 battery, so I'm thinking that it might be a good idea to replace it even if it checks out. Especially since they are on sale for only $20 right now.
If the battery doesn't work, I'm starting to suspect my ignition switch. It is a bit beat up looking and you can pull the key out of it while it is running and it will still run. Am wondering if a faulty ignition switch could be the culprit IF the battery checks out.
Engine is a Kohler cv22. I have downloaded the repair manual for it, but will likely need some guidance as to how to use that manual. If the battery checks out, I guess I will be looking into the procedure for testing the alternator's output.
Thanks to all for any help they might be able to provide.
