I have a 350 rancher that will start with the switch only when the battery is fully charged. I have a fairly new battery and checked to see if the charging system was working and it was. If I let it sit for an hour it will not start. The only way is to use the pull cord. It acts like the starter is hanging up. Any ideas? 3rd. battery and same thing.

Sounds like it might have corroded ground connections. They are connecting well enough to allow current flow when the battery is fully charged, but when it drains a little they have too much resistance to start the machine. Remove all the connections on the starter, battery, solenoid and frame grounds and clean them.

Thanks Pain, I will try that before I rebuild the starter.

That would be my guess also. But could be the brushes or the windings on the starter are pretty bad causing it to not start when it's warm.

How much voltage does the battery read when you get the "no start condition"? Maybe you have a shorted circuit somewhere, causing the battery to drain. If not, then my next guess would be a bad starter.

Try to check the charging system it might be the culprit.
