jd 530 charging

[tpfixit]

Last year I purchased a jd 530 that has been converted to 12 volt neg. ground with an alternator. The alternator is charging but the power is not getting back to the battery. Any thoughts why this is? How does power get back to the battery? Thanks.

Take a look at the [b:654c4848f0]Electrical Wiring[/b:654c4848f0] diagram below for the Model 530.

Note the WHITE lead wire from the voltage regulator on the generator.

The WHITE lead wire connects to the NEGATIVE terminal on the ammeter.

Current flows from the NEGATIVE terminal to the POSITIVE terminal on the ammeter.

Note the WHITE lead wire form the ammeter to the solenoid terminal on the cranking motor (starter).

Current flows from the POSITIVE terminal on the ammeter to the solenoid terminal on the cranking motor (starter).

Note the battery cable from the solenoid to the battery post.

Current flows from the solenoid terminal to the battery post.

The above describes the original flow of "[i:654c4848f0]power[/i:654c4848f0]" from the generator to the battery.

Take a look at the graphic illustration below.

This illustration displays the "conversion" from a 6V POSITIVE ground system to a 12V NEGATIVE ground system.

Note the lead wire from the terminal on the alternator to the NEGATIVE terminal on the ammeter.

Note the lead wire from the POSITIVE terminal on the ammeter to the POSITIVE post on the battery.

We have 3 Model 70s and 2 Model 40s with this same 12V NEGATIVE ground electrical system.

Hope this helps.

There were no 6 volts systems ever used on 50 520 530 tractors they all came from the factory on 12volts
