JD 332 voltage regulator question???????????

hillyridge i have a JD 332,when running,two of the wires coming from the voltage regulator get hot,they get hot enough to discolor the insulation,does anyone have any ideas on this confusing one???? by the way,the alternator IS charging,,,,
Dale G. Basgall Hilly : It appears you have a permanent magnet alternator on that unit, this means there should be two wires the same color and most likely white. They come from the stator coil windings and produce ac voltage in porportion to engine rpm. The higher rpm of the engine the more ac voltage generated. The voltage regulator shows 4 terminals, two for the ac stator side and two that go to the battery, one to ground and the other to positive.

If the wires are getting hot from the stator to the regulator that means there is a current draw when the engine runs and the term hot needs to be clarified as to how hot exactly. Normally you do feel heat in those wires and a discoloration of the insulation is normal if the unit has been around for awhile.

A battery with a bad cell will cause the charging system to work really hard when the engine is running.

Is it the two white wires getting how or the two from the stator to the regulator or are the hot wires going from the regulator to the battery ?

Dale G. Basgall

hillyridge yes,dale,there are two dark wires and two light wires(white and light yellow?),,, it IS those two light colored wires that get hot,,,,the battery is very low in charge right now,,,,,possibly when the battery has more of a charge,maybe,they wont be as hot??? what else could it be? thanks sooooo much for your help dale,,,,
Tony Bachler The charging system is quite complex on that tractor. I would strongly recommend getting the schematic. reg/rect.= 4 out put terminals 2 ac= appx 38volts. DC = 14.4 volts. the other one turns the charging light Plus it is the DC ground For the potential DC differance in voltage. Also make sure the battery is capable of accepting the 14.4 voltage. if not you will get hot parts some were, the voltage must go somewere.
hillyridge hi dale,the battery in this tractor is good,i had it checked,as far as the two white wires,coming from the voltage regulator,they are hot,, they are not hot enough,to melt the insulation,but,they are very hot to the touch,,,,not hot enough to burn ones skin,but,very hot,,,,,other than that,the electical system works fine,and the tractor is putting out voltage,i just dont want to ruin anything, please advise,thanks
