3010 D 24 volt wiring

[Bob Wallach]

Ok I have the wiring just like in gwece's diagrams, had to replace right side battery it was bad. Now after a day of sitting went to start it an the right battery was dead, brand new jump start right up, is there any mods to this diagram or any where else I should look? I have 12 volts with key off between the 2 large terminals on the solenoid is that correct? the only thing is I did use the tractor frame as a ground for the batteries is that a problem. after running for about an hour moving some rock an round bales shut it of an it fired right up so I guess it's charging. thanks for your help.

The mid-point of the two batteries is supposed to be grounded to the frame, giving (-) 12-Volts and (+) 12-Volts with reference to the chassis. Early units simply connected a cable from the (-) of the RH battery (IIRC), and the (+) of the LH battery to ground, Later (safety) versions used a light-gauge wire with a slo-blo fuse.

Dirt, debris, and moisture buildup in the starter or generator will drain the batteries. (As will similar probblems with voltage regulator, the key switch or light switch, or a bad wiring harness laying in damp dirt at the base of the steering pedestal or under the "floorboard".

Also, if the fuel gauge or generator "idiot lamp" are mis-wired, so as to be powered when the key switch is "OFF", they will drain one or both of the batteries.

Bob, The problem you are having is typical when the field windings of the starter are grounding to the frame of the starter. The right battery is wired to the starter post between the starter and the engine block. When the insulation of the starter field windings get dirty with carbon from the brushes and gets damp, this causes a short to frame. To test for this problem disconnect either of the right battery cables and put a test light in series with the disconnected cable and the battery post it was removed from, if the test light lights you have most likely have a starter field coil short. Make sure the key switch and light switches are off when you do this test. Rarely will this be a dead short but a "leakage" short which will slowly discharge the battery. On rare occasion this can be caused by the generator.

You can pull the end cap off the starter and blow the dust acumulation out without taking it off the tractor. When its off make sure the two triangle shaped pieces of insolating paper are tucked under the field winding conection.

There should not be any dust or dirt acculation as the generator,regulator,starter,headlight switch,an wiring are all replaced ith new or remanufactured componets. Only the ingnition switch has not been replaced.I disconnected to pos.cable from the right battery as I was going to be out of town here for a couple days to see if it holds a charge till I get back.
