HV Wire routing underneath

All HV conductors - 2/0 AWG for battery, 8 AWG for charging - are routed below deck and protected by the enclosed drive line tunnel. Outside the tunnel they are protected inside flexible metal conduit.

The rear contactor connects main positive from rear battery pack with 300A fuse to front battery box main negative, completing the series connections.

Main rear negative is the full voltage (120) battery terminal, going to the front contactor box and from there to the controller B- terminal. Main front positive is the full voltage (120) battery terminal going into the front contactor box, through another 300A fuse, and then switched by the contactor upon key-on. Conductor after switching links to the positive side of the controller B+ terminal.

Charging circuit draws power at the front contactor input and is routed through 30A fuses before diving below deck.
