Case 586H 588H Rough Terrain Forklift Complete Wiring Diagram Electrical System Schematics

When a 586H or 588H has a dead circuit, a blown fuse that keeps blowing, or a fault that only shows up when the machine is warm, the service manual will tell you to check the wiring. This is the drawing you check it against. Document 47388793 is Case's electrical schematic package for these rough terrain forklifts: the full wiring diagram, plus a component location sheet showing where each part sits on the machine.

What this manual covers

The schematic is split into 15 numbered circuit groups covering the machine's whole electrical system. Power distribution and charging, starting and grounding come first, then two sheets for engine control, the drive circuits, the CAN bus and diagnostic connector, and telematics. After those come the front and rear lights, instrument cluster, power points, the SAHR (spring applied, hydraulic released) park brake circuit, the horn, and optional equipment. Each circuit shows wire colors and sizes, splice and connector IDs, and relay and fuse positions. A legend explains every symbol and color abbreviation. The component location diagram matches the schematic, so you can go from a wire on the page to the actual connector, relay or sensor on the forklift.

Who this manual is for

Technicians, fleet mechanics and owner-operators tracing electrical problems: a machine that won't crank, a charging fault, lights or gauges that cut out, a park brake that won't release, or a CAN communication error that stops the machine talking to a service tool. It also helps when you're adding lights or accessories and need to know which circuit to tap into without overloading it. With the wire colors and connector numbers in front of you, you can test with a meter at the right pins instead of cutting into harnesses or swapping parts until the fault goes away.

Make sure it fits your machine

This is a wiring diagram package, not a repair or operator's manual, so it has no mechanical, hydraulic or engine repair procedures. Check that your PIN is NCC570000 or higher; earlier machines may use different wiring. The pages are large-format diagrams, so they're easiest to read zoomed in on a computer or tablet, or printed on large paper.
