Voltage regulators will keep the voltage at around 13.5 to 14 volts with the vehicle running. This is what keeps your battery charged while driving the vehicle. If is lower than battery voltage (usually around 12.3 to 12.8) then it is probably bad.

Battery not charging


Most likely a faulty voltage regulator located on the inside firewall. Look for the cooling fins on its exterior. It can be tested or replaced. Secondly, inspect the wiring that comes from under the flywheel making sure its not broken or cooked. Lastly, the flywheel may need to be removed and the magneto replaced.

Replacing voltage regulator


Not sure what you mean when you say Replacing voltage regulator. Would need to know the model number of the engine however as a general rule a voltage regulator is fairly easy on most of the John Deere mowers. As with any electronics when you buy they are not returnable. Depending on the engine you have a voltage regulator can be costly and may not fix your problem.

Of the 100+ camshaft replacements that I personly have done on the 425/445 and John Deere Gators I have come across 3 that backfired when completing the replacement.2 were do to bent valves coming in contact with the piston after gear failed and 1 was from a sheared flywheel key.The only other time I had this same injected engine backfire was on a John Deere gator 620i that had a faulty computer and fired @ 90 derees off.Do a compresion check and that will help out alot.

The charging system on the mower will not charge the battery up


The first thing to check on this machine is your voltage regulator try bypassing the voltage regulator to see if the alternator starts charging, it would be better to check your charging system with a voltmeter so that you know what the exact input and output in the electrical system.
