    It has an alternator, but it's rather different than your truck.
    With the engine running at high speed, measure the V at the battery terminals. It should be around 14ish.

    Are the fuses between the seat and contol panel side good? If the fuse is bad it won't charge. If it has a bad fuse replace it and charge the battery good. I had a simliar issue last year and this fixed it.

    I would check the charge at the battery. I thought the generator was part of the starter on these motors.

    Brian I had the EXACT same problem last year. Found 1 of the 2 exterior fuse holders was defective due to grime and grease and dirt. I checked the fuse itself and it was good. I cut out the old fuse holder and installed new one and had problem corrected. Many Thanks to Scag Tech Support Help. Also you can download the manuals from scags website and it will have a wiring schematic in it.
