    Port Battery Charging Issues

    Hey Guys,

    I just bought a 2007 SANTE 220 Last fall. I've noticed it has an issue with the port battery. Seems that battery is not charging at all. There's no corrosion on the terminals. My Amps are all directly wired to this battery. That's how the PO had them ran instead of running the wires back to the battery switch. If I hook my meter to the Port cables I get a very weak trickle charge while the engine is running. I can start the boat on the Starboard battery, switch the selector to port and run for an hour or two and still not be able to crank the boat over on that battery. Take the boat home and hook up the charger and that battery will last for about 2 hours on the water, stereo on, before its dead again.

    No issues with the Starboard battery charging and I can't remember the numbers on my meter off my head on both sides either. The engine was just replaced in the boat before I bought it. I've had the battery checked and they say its fine. I'm down to 2 possibilities, bad ground, or bad cables.

    How should the ground wires from both battery ports be grounded to the engine? Same spot to have a mutual ground? or different locations on the engine?
    Has anyone known or heard of corroded cables on 9 yr old boat? My other boat is an 87 and its still all original.

    It would really help to know what the voltage was on both banks while the engine is running. A voltage drop test on all the battery cables would be the next step. This will tell you if you have either a ground or cable issue.

      Voltage or Amps? Since the Port battery would be dead I'm sure it would pretty much show "0". Unfortunately, I am deployed and won't even be near my boat until the first of Aug, which sucks!. I guess I was just trying to see if anyone else had the issue or might be able to steer me in the right direction with some of the information I have.

      I'm sure I can Google it but since you brought up a voltage drop test on the cables, how would I do that?

        Voltage is just a difference in potential between the high side and low side. If a cable is bad and resistance is high, there will be a difference of potential between the two ends. This shows up as voltage. Put the meter leads on each end of the cable
