    Voltage Question

    My friend and I have two 2003 SAN's with basically the same stereo and battery setup. When my boat's voltage drops to the low 12 volt range I get the " low voltage" alarm. When we were on his yesterday his dropped down like that and it never alarmed. When the boat is running with nothing on his was showing 13 or more volts and mine never makes it past 13 volts. Has anyone had this same issue? Where would be a good place start troubleshooting? I can get the Alt. checked and I thought I read something about the guage of wire to the fuse panel being two small.

    The very first thing you do is get an accurate voltage meter, and use it to check the voltage in both boats.
