Been trying to find a ground that has been draining my battery. Bought a seloc manual (thats a whole different story). been chasing my tail on this one.
when running the engine, battery stays at 12.3 volts. voltmeter at helm displays 11.8 volts. over time, the voltmeter at the helm will drop down to 11 volts, but the battery stays at 12.3. took a reading at the main cable at the alternator, read 12.3.But at the small wire at the alternator, reads 11 volts.
I ran the boat for about 30 mins just on the battery (radio, engine blower, vhf radio, gps, navlights, courtesy lights). battery stayed around 12, but the voltmeter at the helm dropped down to 10 volts.
Now looking at the manual all this comes from the M1 fuse at the fuse block. It feeds the instrument panel through all the purple wires.following all the purple leads, it feeds the helm panel, as well as sends voltage to the alternator.
so i dont know what the purple lead to the alternator do? does it send voltage to the alternator to tell it how much it should output for charging?
and puzzled about the readings I am getting. I know the voltmeter could be off. I checked voltage at the back, and it was pretty close to what meter reads..
