Dual Battery Winch Wiring Diagram - Alternator, Starter, Fuse & Isolator Sketch

This is a simple, hand-drawn (computer-sketched) wiring diagram uploaded to a 1978 Chevrolet C/K Pickup gallery showing a dual-battery winch installation. The diagram depicts an alternator (ALT, yellow circle) and starter (STARTER, green oval) connected through what appear to be two relay/solenoid or battery-isolator components (red circles) to two batteries, each shown with positive (+) and negative/ground terminals. An inline fuse (green rectangle, labeled 'fuse') is placed in the circuit between the solenoid/isolator area and the batteries, and a red feed wire runs from the fuse area down to a WINCH (blue box). Two unlabeled boxes at the top likely represent additional components but carry no legible text. The diagram conveys the general wiring topology for charging two batteries from one alternator and powering a winch, with fuse protection on one leg. No wire gauges, amp ratings, part numbers, colors codes (other than the drawing colors), or vehicle-specific details are given, so the schematic is generic and could apply to many vehicles, including the claimed 1978 Chevy pickup.
