The windlass breaker?? Mine was on. I just checked the voltage to the windlass solenoid and only had 6.5 volts to the input side. Checked the battery voltages and found the port engine battery at 6.5 volts. The starboard battery was at 12.6 volts. Doesn't the charger charge BOTH batteries? Anyone have the battery wiring diagram for a 2004 288 without the genset? Thanks!!
How many batteries to you have in your boat?
I don't like the way four winns wired the batteries and labeled the wires.
Yes the charger should charge both batteries, or both battery banks if you have more than 2 batteries.
The battery charger is tied into the switch so you will not see the wires.
On my boat the red wire labeled port engine is tied to my starting batteries. My 2 starting batteries are on the same circuit and connected in parallel.
The house batteries are connect to the red wire labeled starboard engine.
Seeing as your staboard engine battery is dead, and tied into your windlass i would suggest this is your house battery, and your boat is wired the same as mine.
How old is your battery, and did you just pull the boat from winter storage?
Turn your battery charger on and check the voltage at the battery. It it reads 12v or higher your charger is good and battery is done. If no change in voltage your charger is done, and your battery might also be.
Have you recently run the boat? The alternator from one of the engines will charge that battery as well.
