782 battery gauge drops w PTO on

[MarkEStock]

I have a 782 Cub with a Kohler Magnum engine and the machine runs fine until I turn I on the PTO and the battery gauge drops off and runs rough. I only have 1/2 aches and the engine is really hot and eventually cuts off towards the end. The battery is a full 12 volts and the issue just started. Any guidance would be appreciated!

Have your battery load tested, most any auto parts store will do this free, a good battery should be well above 12 volts.
Adjust your PTO clutch according to the 782 operators manual.
If it's getting hot you may need to remove the engine so you clean behind engine shrouds. It's not as hard as you would think.

Look at your charge gauge when you start and run the engine and see if it is charging the battery. If not the PTO pulls a lot of electricity to operate. It will discharge a battery in a little while.

Unplug the PTO and turn the switch on. If everything stays normal tractor wiring is probably fine. Take an ohm meter an hour from the wire on the PTO to ground. Should get between 2 and 4 ohms. Lower readings indicate a short in the PTO coil which will cause a high amperage draw and discharge the battery to a point where it will not have enough power to run the tractor.

Have the battery load tested at the local parts store Check for voltage drop at the pto
