Re: 2011 JD Gator TX alternator HELP PLEASE
First, you appear to be doing the "throw parts at it hoping to fix it". You may wish to rethink that process, unless you have lots of money.
Second, The main alternator bits are probably under the flywheel of the engine, so you'd have to get that far into it. You might look up the parts diagrams for your specific model, that should tell you if you have the right parts and roughly where they go.
Third, before digging into the motor, I would suggest testing the regulator, as it is more likely to have failed than the bits under the flywheel. It generally is also more easily replaceable, but I have no specific knowledge of your particular engine to know for sure.
