I converted a 620 john deere to a alterator system and now cant get it to charge if some one could show me were all the wires go I might be able to figure this out When I turn on the lights it shows a 20am decharge when I run the wires the other way it show a 20am charge its a new alterntor and with the old one it did work but suddenly it wouldnt start unless I took the wire of the alterntor that was to excite it. thats when I noticed it wasnt charging so now Iam confused totally any help would be welcome Phillip_Julch@yahoo.com

You wouldn't have had this problem if you hadn't tried to "improve" the tractor with an alternator conversion and attempting before understanding wiring/electricity. The old generator was a high output 20amp with more than adequate capacity. Now the tractor's value has dropped, you are looking at a mystery tangle of wires, likely had at least one arcing & sparking session, the battery isn't charging. And after many of these "improvements the fan belt is running out of alignment. Just mark the old wires, get the generator repaired and do the easy, fast, less stressful and safe thing by putting it all back to the way it was. At least your troubles will help steer other's away from this common mess.

While I wouldn"t put it quite as strongly.... ;)

Kinda how I feel about these 12v conversions too. Always have steered clear of them.

The "+" side of the ammeter gets connected to the alternator, the "-" side to the loads. Ammeters are marked.

For further information, search this site. There is a tech article that covers this subject.
