1641 charging issue?
 

The amp light on my tractor comes on whenever I engage the PTO. Also comes on intermittently while driving without the PTO engaged.

New battery.

Should I suspect the charging system or a short? Something else?

Thanks.

I would suggest to put your volt meter on the battery and check voltage @ idle and full throttle which should tell you the status of your charging system.
With engine off you should have about 12.6 V if fully charged battery and it has been sitting a day, as the rpm's increase it should put out a max of about 14V or so.
Switching on a load as in headlights or PTO voltage will drop but should still stay above about 12.5
This is general for most charging systems.

Thanks. Will check as suggested.

The voltage light is a very common issue. As George suggested check it with a meter and if it's OK take the bulb out of the indicator. I replace the lights on my tractors with gauges.
