is the 4th generation (I've had the boat for 27 years this summer) which began with OEM wet cells then a pair of 8D gels and then a pair of 8D AGMs with an Opitma Start batt.
In the 3rd generation I added the PV 14, Link20, Sulfator and Echo-charge, and Amp Tech alternator
and a BlueSeas 8080 swtich. In the second generation I has a Cruising Power Quad Cycle monitor
using the OEM Bosch alternator
In the 2nd generation I added 2 - 55watt solar panels
. (unregulated w/ blocking diodes) and added a second battery
switch to be able to select any combination of batteries for power (old school
sources charge the house bank - 2 8Ds and the charge the start batt with the echo charge...
Start batt only cranks starter and is usually 100% full
All batts are run to the shunt, all devices have ground wires to a neg buss.
Large draw loads have large busses (pos and neg) and are located in engine
room and include... starter, alternator, windlass
, house loads, inverter
. I've attached a to scale diagram without the wires of the large load electric wiring
in the engine
room. (green hatch
