- Incorrect installation of the time delay module: If the time delay module was not properly connected or secured, it may cause a short circuit or drain the battery.
- Faulty time delay module: Even though it's a new part, there's a chance that it may be defective or malfunctioning.
- Issues with the wiring: Inspect the wiring around the time delay module and battery for any signs of damage, loose connections, or corrosion.
- Alternator problems: Verify if the alternator is properly charging the battery. If the alternator isn't generating sufficient voltage or has a faulty voltage regulator, it won't recharge the battery and may lead to drainage.
- Parasitic drain: Some components on the tractor, like lights or accessories left on, can drain the battery over time, especially if they're not properly switched off.
- Faulty ignition switch: If the ignition switch is malfunctioning, it may not effectively turn off the electrical components of the tractor, causing the battery to drain slowly.
- Old or damaged battery: Batteries eventually wear out and lose their capacity to hold a charge. If the battery is old, sulfated, or damaged, it may not be able to store sufficient charge and could drain quickly.
To properly diagnose and resolve the battery drain issue, it is recommended to perform further testing, such as checking voltage levels and continuity with a voltmeter, and isolating different electrical components to identify the source of the problem. If the issue persists or you're not confident in your diagnostic skills, it's best to consult with a qualified technician or consult your tractor's service manual for specific instructions based on your specific John Deere 345 model.
