Having Boat Electrical Issues?Here's A Simple Solution To Common Electrical Issues On Your Boat
Have you experienced boat electrical issues and quicker battery depletion? Your boat’s Voltage Sensitive Relay system could be the issue. Our MasterCraft technicians offer a solution to keep your electrical system performing correctly.
Every X-Series boat- 2012 and newer, has dual battery systems. Our battery system is set up to keep one battery reserved for starting the boat (starting battery) and the other battery (house battery) for powering all onboard electronics (stereo, screens, dash gauges and lighting, etc).
MasterCraft uses a simple OFF/ON/COMBINE switch, with a Voltage Sensitive Relay (VSR) system, designed to simplify and automate the battery system.
What Does The VSR Do?
The VSR will transfer charging power to each battery, as needed, to keep both batteries at the optimal voltage level.
- OFF: The OFF position disconnects the batteries when in short or long term storage (more than 2 weeks) to prevent the batteries from depleting.
- Note: The bilge pump will stay hot regardless of battery position
- ON: The ON position is switched once the boat is out of storage. In the ON position, the START battery and HOUSE battery will connect.
- Note: To fully activate the house systems, you must also turn the key switch to the ON position.
- COMBINE: The COMBINE position allows the HOUSE battery to supply power to start the engine in the event of a depleted starting battery. After the engine is started, the switch should be turned back to the ON position, to allow the VSR to properly allocate voltage from the charging system.
Note: The COMBINE setting should be used for emergency situations only, such as when the START battery is dead. Prolonged use in this setting will inhibit the VSR’s performance, causing both batteries to drain rapidly. MasterCraft has found this to be the leading cause of electrical issues.
