My battery light on the TC40DA is on. The battery is 6 years old but I do not think that is the problem. It starts right up and runs with no issues. Checked all the connections. When I engage the PTO the gages on the dash will drop, Temp back to cold, RPM gage will drop to zero. Disengage the PTO all gages go back to normal. Is this an alternator issue.
Jep;
Does the battery seem to stay up after lots of repeated startings?
If so then I don't think you have an alternator issue. Your symptoms seem on the order of a grounding issue somewhere that you haven't found yet. guages don't take much juice, but a bad ground messes them up.

If you mean start up yes it starts right up. The Battery light just start staying on 2 days ago so I would assume their is a enough of a charge in the battery for now. I probably have started it a dozen times since the light started to come on when the tractor is running.

I'm not going to go much further here, my electrical knowledge wouldn't light much of a warning light. I had several Case farm tractors with plastic fuel tanks, the guages usually worked for a couple years after the tractors were new, then quit. The senders were never bad just a bad ground, but not always the easiest to find.
Maybe a Ford/NH owner could guide you further here.

Well I still have the problem & have not been able to find what the issue is. I checked and replaced all the fuses, tested and cleaned the relays, checked all the grounds that I could find, tested the battery and alternator. Problem still there. In addition to the above problem my cruise control and the hi/lo does not work. I guess I will be sending the tractor to the shop this winter if I don't get lucky and find the problem. At least the tractor seems to be running fine.
