Unless it has the auxiliary alternator(looks like a car alternator with a belt) then it has a charging coil under the flywheel that connects to a regulator on the right frame rail of the gator under the bed. I assume you have checked the fuses and the ignition switch to make sure the are as they should be.

Most likey a stupid question. But can I add a auxiliary alternator to my gator??

19931994Factory option for an upgraded alternator is a mini alternator like a car or small 3 cyl diesel engine. remove the plastic flywheel cover ( passenger side) there are three bolt holes in the flywheel. The factory bolts a pulley to the flywheel, there is a knock out on the plastic cover to allow the belt to pass through. I had contemplated adding an alternator to mine as I have added a winch, 4 spotlights, and tail lights. They were all draining my battery to the point it wouldn't start anymore. I instead opted for a Red top OPTIMA battery it fits snugly into the battery compartment after removing the plastic battery tray. The stock alternator is 20 amp the optional external alternator is 60 amp.

05gator, by chance did you price that little gem out complete to install? I did the same thing you did and installed a 700 cca car battery working great for me.

No, If I was to add an auxilary alternator it wouldn't be john deere simply for the price I'd fab it myself. I just looked up the price through our local dealer and it says $356.31 (BM22449)

Hi Paco, if you havn't found your problem yet you can ohn your two stator wires for continuity and to grnd. Those two wires go to rect reg on rt rear inner frame rail. unplug to check hot two stator wires 15 to 30vac engine running, If you AC there then check for DC to Bat. Also could be blown or burnt fuse

Ok so if one of you guys would know how to go about making a alternator for my gator could you let me know?? I really don't want to pay John deere price �� lol

If you want to add an alternator, it will require fabrication on your part. First remove the black plastic cover on the engine, Passenger side, under the cover should be the flywheel you will notice in the center there are four threaded bolt holes you will need to fabricate a pulley to bolt on here. The black plastic cover should have a Knock-out to allow the belt to pas through it. The alternator is mounted in front of the engine.

Here is an example of an alternator:

Built a bracket that mounts the alternator like an old Chevy. On solid side that will pivot and the other a slotted arm to allow the belt to be tensioned. Alternators like the one above are internally regulated, however they require a 12 volt switched circuit so that the alternator can "sense" the voltage in the circuit. They also usually have a wire that runs a light to indicate alternator failure "no charge". Wiring diagrams can be found for the alternator once you pick one, but it should be small, as the engine is small, and don't use too big of a pulley to drive the alternator. This will rob your engine of power.

no problem

Put a voltage regulator on ti. It's real easy to do. $67 at an dealer.

[rodbuilder]

You can add a 350 Chevy engine to it if you have enough money!!!!!!

[rodbuilder]

Change the regulator. It's on the inside of the "frame" and is about 3" square x 1" thick. About $65 from any dealer.

You can ad anything to anything if you have enough time and money to do it! Adding another alternator isn't the problem, it that a Gator doesn't idle fast enough to charge it iof you did add one! If you leave it idling all the time you need to add a solenoid to the throttle mechanism so you can idle it up with a switch when you're off of it.............like the ones on an older car with a carburetor on it.
