John Deere L111 PTO Clutch Voltage
I have an old ('80s) model J. Deere L111 with a new battery. After mowing and shutting off the engine, the battery is too low on voltage to restart. I tested the charging voltage with the PTO off (with the engine running at operating speed), and the voltage reaches about 14 volts. Leaving everything in this condition, when the PTO is started, the voltage starts to drop, until it reaches about 12 volts. With the PTO off, charging voltage again climbs to 14 volts.
Is the PTO drawing too much voltage?/Is it rebuildable?/What is the correct charging voltage with the PTO on? Simply, what are my options, assuming I have narrowed this down to the PTO clutch. Thanks for any help.
