at all careful when working around the regulator. Operate starter and compare readings with below: G to.2 volt max B to.2 volt max C to.2 volt max A to.1 volt max C to.1 volt max Voltage readings that exceed these indicate defective wires. However, you can successfully charge (with the charger set on 12 volts) both batteries in series at the same time only if both 6-volt battery voltages are within.1 volts of each other. The current then goes from A 1 to the voltage regulator ARM terminal, through the regulator, out the Blue wire to BAT A on Ignition Switch, to load if needed (lights, etc) If no load, then current will flow on Blue wire from BAT. Make sure you know the polarity of the system and the voltage of the system. Closing voltage must.5 volt or more below the voltage regulator setting. Other possible causes could be a bad battery connection or low battery. The 50 ohm resistors are provided on the ignition switch to guard against a sudden surge of voltage or in the event 24 volts should ever arise at that point. From ground post on left side battery to ground post on right battery.1 volt max. Like the full water storage tank that slowly evaporates and must be refilled, so goes the voltage in a battery.

How to Convert a John Deere 4020 From Two Batteries to One
Even though a trickle charger is only delivering a trickleh of a charge, if left on the let's talk hookup youtube battery too long, the battery can overheat. The problem came in when we tried to find accurate knowledge on wiring and how the electrical system worked. We later purchased a 720 Diesel that came with electric start. Many have found that a trickle charger. Simply plug in the maintenance charger, put the leads on the battery, and wait until the winter snow melts. It worked fine, but wasn't wired to our diagram below. When installing the battery, connect the ground cable last to help avoid sparks. If voltage drop is under max, connect regulator lead and re-polarize generator. Bringing an idle engine to life requires the battery to generate enough amps to spin the starter to turn over the engine.
Wiring on the 4010 and some 4020 series) provides little if any safety factor as has.
The John Deere 4020 tractor was manufactured with a pair of 12-volt batteries wired in series.
Both batteries are wired to the 24-volt starter.
