Hello 2000 tc 30 new Holland tractor … beeps and won’t turn off with key, hot fuel solenoid, I have heard other people have the same problem with new Holland tractors. The fuel cable is hot even with the key switch off. Someone said maybe the hot feed from the bad voltage regulator on the alternator. We test all relays on top and safety switches with the test light.
So the fuel solenoid stays energized?It can be a feedback from a bad voltage regulator in the alternator.A bad diode will let the voltage feed back.I assume the engine stalls if the solenoid is disconnected?
