Dual Battery Parallel Wiring Diagram - XS Power D3400, Mechman 240A Alternator

This document is a color-coded wiring diagram for a dual-battery, standard-parallel car audio power system, uploaded to a 1994 Ford Bronco gallery. It shows a Mechman 240 Amp alternator whose charge cable passes through a 250 Amp MEGAFUSE to a junction stud that also feeds the starter (yellow wire labeled "TO STARTER"). From this junction, red power cable runs to two XS Power D3400 batteries connected in parallel. Grounding is shown in black cable from a chassis ground symbol, tying the batteries to the engine block/frame ("To Engine Block/Frame"). Two power runs leave the battery bank, each protected by a 300 Amp Megafuse, and terminate at a Distribution Block. From the distribution block, fused power leads (inline fuse holders drawn but amperages not labeled) supply two Hifonics amplifiers. The diagram tells a reader the recommended fusing scheme (250 A at the alternator, 300 A per battery feed), the battery model used (XS Power D3400), the alternator upgrade (Mechman 240 A), and the general cable routing and grounding strategy for a high-output dual-battery audio installation. It is not vehicle-specific, no year, make, or model markings appear in the diagram itself.
