Hooked battery up backwards JD LT 133

[tjburris]

I bought a new battery for my John deere LT 133 and did not pay attention to the + and - posts. They were reversed. Wire started smoking, got the correct battery, and the wires still smoke when I try to hook it up. The key is off. How bad have I screwed it up?

I would check the fuse panel and the wiring harness. There may be damage to the alternator. A lot depends on the length of time that you turned the ignition. Just a thought? Best wishes.

Sounds like the alternator diodes are ruined.

A friend of mine tried jumping his tractor and hooked up the jumper cables backwards. Blew some fuses, but that was all. Where is the smoke coming from? Both wires? Ground wire? Alternator?

Hard to guess your particulars, but that's the thing with DC. Many components and devices are extremely intolerant of reversed battery polarity. Whether its a tractor, or your TV remote, we don't want to make that mistake. Bad things can happen. Today, more and more things are controlled electronically. Any of these circuits can be subject to catastrophic damage and expensive repairs. Don't ask me how I know. Good luck.

My bet is it either blew the fuse to the alternator, or if unfused, it burned the diodes out in the alternator..Sometimes it will blow instruments and the tach.. I did this to one of my boats ..

john deere shows your model not having an alternator but having a stator thats runs directly off the motor it can only be found by removing top cover of motor and it generates power by the spinning of the motor if this is the problem they can be bought or can be rewound. it does show it to have a regulator which john deere will have in stock possibly it is burned up but also look for fuses burnt wire possibly relays or some other type of switch that could be in-line with the charging system. if yours does have an alternator it will be a permanent magnet model will look like an alternator but very pancake look it can also be burnt also good luck

I cant see exactly where the smoke was coming from. It seemed to come from below the solenoid. It wasn't the ground or positive wire, there was a little black wire that was extremely hot to the touch. I could not see exactly where it went. I needed a flashlight and didn't have one handy. I believe something is welded together as I cant hook the battery up correctly without it heating up and smoking. I think it is something to do with the ignition system, but I wont be able to get into it until next weekend.
