Have this problem on my New Holland LX485 all of a sudden. Only ways to save the battery is to pull the fuse for the electronics or the negative battery cable. Anyone out threre have a similar problem or a possible solution?
Id be curious as to what else is run off the fuse for electronics. Do you have a wiring diagram. If electronics has its own fuse, and is not shared with any other circuit, then your problem would be in the board, or any related components, stuck relay, short to ground. If there are other circuits tied to it, then that would be a place to look at, and eliminate first, but you really need a diagram to know what up.
Disconnect the small wires on the alternator and see if it goes away.
Not the red, straight to battery wire, just the excite and charge wires.
Did you look at the relays in the engine compartment ? If one is sticking will do weird stuff.Just went to shop and disconnected wires from the alternator excite resistor and instument cluster works as it did previously. Does mean the resistor is bad or do I have a bigger problem? Thanks, you were right on.
Either the resistor or the voltage regulator. A pic of the alternator would help me guess better, maybe somebody else knows for sure.Just went to shop and disconnected wires from the alternator excite resistor and instument cluster works as it did previously.

Have not located a resistor replacement yet as apparently it is not a standard "off the shelf" resistor to be gotten from an electronics supply house. Should fix problem as the old one would not pass any current.So you fixed it with a new resistor? or what's going on?
