Voltage issues are a common culprit behind fishfinder and trolling motor malfunctions. Low or fluctuating voltage can lead to a variety of problems, from poor performance to complete shutdowns. This post will help you understand the causes of voltage issues and provide practical solutions to keep your gear operating smoothly.
Common Causes of Voltage Issues
- Battery Problems: A weak or dying battery is the most common cause of voltage problems. Even if the battery appears charged, it might not hold the charge under load.
- Inadequate Wiring: Thin or damaged wires can cause significant voltage drops, especially over longer runs.
- Poor Connections: Loose or corroded connections can cause intermittent voltage drops, affecting the performance of your fishfinder or trolling motor.
How to Diagnose and Fix Voltage Issues
- Test the Battery: Use a multimeter to check the battery voltage under load. If the voltage drops significantly when the fishfinder or trolling motor is running, the battery may need to be replaced.
- Inspect Wiring: Ensure that the wiring is the correct gauge for your setup. Replace any damaged or inadequate wires, and make sure all connections are tight and free of corrosion.
- Use a Dedicated Circuit: For best results, run your fishfinder and trolling motor on dedicated circuits with their own fuses and switches. This helps prevent voltage drops caused by other devices on the boat.
By addressing these voltage issues, you can ensure that your fishfinder and trolling motor perform reliably, helping you focus on catching fish rather than troubleshooting problems.
