My john deere 757 tractor has a charge light that turns on when the PTO is engaged. It is an intermittent problem, but it can be fixed easily. I checked the battery and it was good, so I thought I’d take a look at the other components. However, I noticed the charge light was on when the pto was engaged and the pto clutch was broken. I purchased a new PTO clutch, and this has solved my problem.
To diagnose the issue, check the charging system. If the light comes on, you can check the battery. If it is fine, then you can check the alternator and the voltage regulator. If these are not the culprits, then you will need to change the PTO clutch assembly. It’s likely to have a faulty rotor and armature. The alternator is the first part to be checked.
You can also check the wiring. If you can’t see the red wire, make sure the battery is charged and plugged into the positive side of the PTO wire jack. If that works, the charging light should come on while the pto is engaged, and it should go off when the PTO is not engaged. If you can’t find the wiring, try installing a jumper wire. Then, plug in the negative alligator lead of a test light to a ground source.
Another common reason why the charging light turns on is because of a faulty electrical circuit. In such a case, the power takeoff pulley may not stop rotating even when the clutch is engaged. If you are seeing this, check the plates of the PTO to make sure they’re not galled together. Similarly, check the main power wire on the clutch side and pull it away from the deck. Then, connect the negative alligator lead to a ground source.
In the case of a faulty electrical circuit, the charging light is triggered only if the PTO is engaged. If the PTO is engaged, the charge light will turn on if the engine doesn’t turn off on its own. This problem may be caused by a malfunctioning electrical connection. This problem may be a sign of a faulty electrical circuit.
A faulty electrical circuit can result in the charging light to remain on despite the pto being engaged. The power takeoff pulley may not stop, which may indicate that the clutch has galled. If the charge lamp does not turn off, the main power wire should be pulled away from the deck. To test the lights, make sure the batteries are charged and the charger is properly connected to the pto.
If the charge light does not come on, the problem could be caused by the power takeoff pulley not stopping when the PTO is engaged. Alternatively, the power takeoff clutch may be damaged or galled due to excessive heat. If the charge lamp does not come on, the power takeoff clutch may not be engaging, or the wiring may not be connected. If this is the case, you should check the main power wire.
If the charge light does not come on when the PTO is engaged, you should first test the power takeoff switch. The PTO is a crucial component in the tractor, and it is a simple way to verify whether the PTO is working. You should also check the cable connections and the electrical wiring of the PTO. In addition to the battery, the PTO should be clean as well.
If the PTO switch is in the right position, then the main power wire is connected to the power takeoff pulley. The clutch is engaged when the PTO is engaged. If the charge light does not come on, the problem is in the power takeoff pulley. If the power takeoff pulley is not engaged, then the issue is the electrical circuit in the PTO.
