Frequently Asked Questions (FAQs)

1. Should I have a battery switch on my boat?

While not all boats have marine battery switches, most boaters can benefit from having one. Boats often have multiple battery banks due to the various electrical components they have, such as trolling motors, fish finders, and radios. A battery switch allows for better control and management of the batteries on the boat.

2. Is the disconnect switch on a boat battery positive or negative?

The convention is to have the disconnect switch on the positive side of the boat battery. However, there is no technical reason why one side is better than the other. It's essential to refer to the manufacturer's instructions and follow their recommendations.

3. Does the bilge pump work with the battery switch off?

No, the bilge pump typically has two hot leads. One is connected to the battery switch, and the other is connected directly to the battery and the float switch. If you turn off the battery switch, the bilge pump will not work because it relies on the direct connection to the battery.

4. Should the battery disconnect be in the on or off position?

When storing the boat, the battery disconnect switch should be switched to the "off" position. This helps to prevent the batteries from discharging while not in use and helps to preserve their charge. It is good practice to follow the manufacturer's instructions and guidelines for proper battery maintenance and storage.
