Howdy,
Got an old JD3040 and I have alternator problems.
The alternator has 2 leads: a thick red one -I bet this is alternator output
and a more narrow gauge wire leading in to the cables entering the cabin.
I bet this is the field voltage.
This terminal reads zero volts when tractor is running. and I have battery voltage (12.3V) on t he alternator output so its clearly not charging.
Does anyone have a wiring diagram that shows where the field wire goes in the cabin?
I have problems tracing its origin and its got to be broken/disconnected/or...
thanks
Otto
