Battery banks

House bank - 2x 105 Ah SLA. Effective 100 Ah. Starter - 1x 80 Ah SLA. Effective 40 Ah.

Alternator

BV PSH 80A, Hitachi saddle mount. Sourced from Myles Balfe. V-belt sheave.

Part number is 985.001.080.200.

Terminal and driver sizes

Area Item Fixing Driver Stud
Battery Shunt Terminal 10mm 8mm
House Terminal 14mm 10mm
Starter Terminal 13/14mm 10mm
Blue Sea Fused Bus Terminal 10mm 5mm
MIDI fuses Terminal 10mm 8mm
Negative bus Terminal 14mm 8mm

Core power distribution and charging

This diagram is for the wiring in the starter and house battery bank compartments.

Charge and Distribution fuses are MIDI style with spare, Blue Sea 7720.

Solar charger fuse is inline automotive.

To-do: Replace direct-to-terminal with distribution bus bars. Starter negative terminal has more than 4 cables attached.

Blue Sea Ancillary

This distribution setup is used for power distribution in the saloon; it's in the same physical area as the batteries. Distributor is a Blue Sea Systems ST compact 8-circuit (5046) with 10-32 stud, and 8-32 screw terminals.

Always on distribution

This powers low draw devices that should be powered without the house switch being engaged. Basically, lights. Located in the wiring cabinet above and behind the chart table. Wired to supply side so it's always got power, bar the local fuse blowing.

Water pump

Wired via a relay so that the switch by the chart table just activates the relay, and the pump gets power from 6mm2 direct from the battery compartment.


The relay is the same as the one for the engine starter, 12V 40A SPST with 30/85/86/87 terminals, normally open.
