This would be a better way to have a direct charging wire.
Downstream of the battery is still protected by the fusible links.
Power from the alternator goes direct to the main junction.
This makes sense that you get power straight from the alternator via a low resistance path. But what if the charging jumper blew? Wouldn’t all the power be redirected through the bulkhead and main junction, exactly where we didn’t want it?
Doesn’t it make more sense to run a new, fused, heavy wire straight to the battery, then redo the wires leading to the junction so that there’s only one fusible link (choke point) instead of two? That would cut down on resistance while ensuring that the alternator’s output never gets routed through the bulkhead.
