Just added blue sea systems "add a battery 7650"
When the engine is running it shows 13.8-14volts on the dash gauge but only 10.5 on the cap digital readout. If I move the battery switch to combine it reads 13.8 volts on the cap. See my wire diagram below. The boat runs fine but the stereo is cutting out due to insufficient amount of power. Any suggestions? All wires are 2/0 gauge except the stock 8ga wire on the alternator to the starting post on the motor. Is this a potential bottleneck?
