Tadano FAUN 214 Electrical Schematic – Factory OEM Wiring for the Chassis

You ever chase a short in a chassis harness and end up replacing a perfectly good solenoid because the aftermarket diagram had the pinout flipped? I’ve been turning wrenches since before most of you were born, and I can tell you right now – the difference between a job that goes smooth and one that goes sideways is having the right factory electrical schematic. This Tadano FAUN 214 Electrical Schematic is the real deal: 49 pages of original OEM data, not some scanned reprint with washed-out lines. If you’re working on a FAUN 214 chassis – whether it’s a crane carrier or a heavy equipment hauler – this is the document you want on your tablet or printed out on the workbench.

Engine and Chassis Circuits: Page 2 Breakdown

Page 2 gets straight into the critical control circuits. You’ll find the batt. charging plugbox, the plugbox for start engine from external source, the slipring chassis/crane interface, and the relay, ignition ON, chassis side. That’s the stuff that keeps the truck alive when the crane is drawing power. Also listed: the electric batt. main sw and its relay contact, the ignition starter sw, the sol. valve, cooler control, the relay contact, gearbox starter interlock, and the adaptation module, vehicle engine control. Every component has a reference designation so you can trace the wire gauge and pin location without flipping through three different sources. If you’re replacing an engine control module or troubleshooting a no-crank condition, this page saves you from guessing which wire is the starter interlock.

Does This Manual Cover the Lighting System Fully?

Yes. Page 4 lays out the entire light circuit: bordering lights front and rear, left and right, side marker lamps (multiple positions), license plate lamp, rear light left, trailer plugbox N, and the slipring chassis/crane again. You also get the light sw and the French-specific bordering lights. If you’ve ever had a trailer plug that kills the chassis lights, this schematic shows exactly where the ground path splits. No chasing ghosts – you can meter from the switch output to the lamp socket.

49 Pages of Factory-Original Data

That’s the whole document: 49 pages, every wiring diagram drawn to Tadano FAUN’s internal standards. This isn’t a generic “hydraulic and electrical” combo that lumps everything together. It’s specifically the electrical schematic for the chassis portion of the FAUN 214 (Part D1). The circuit numbers, relay coil resistances, and diode groupings are factory-verified. You get the diode group, ignition, chassis, the diode group, CGC supply, the diode group, “+” CGC, and the relay, generator D+ – all on page 3. These are the bits that prevent backfeed through the crane control. I’ve seen guys blow a $1,200 ECU because they didn’t know about that diode group. Don’t be that guy.

Verify Your Ground Paths Before Powering On

Page 5 covers the superstructure-tied lighting and accessory circuits: light from the superstructure, the relay, working speed, remove connection of optional equipment (two of them), relay intermittent wiper operation, washer motor, wiper motor, super tone horn, electric horn, and the steering column sw intermittent wiper action washer. Also listed: the rocker sw, super tone horn, rocker sw, fog light, relay, fog light, dimmed light, left and right, and the steering column sw high-beam/dimmed light/horn. The statement “remove connection of optional equipment” is a factory note you will not see in a third-party diagram – it tells you where to break the circuit if a retrofit is installed. That piece of information alone can prevent a short-to-ground that melts a harness.

3 Critical Safety Checks from This Schematic

First: the relay contact, engine stall device on page 2. If that relay fails closed, the engine will not shut off with the key. Second: the diagnostic controller connection – make sure pin 4 (if shown) has continuity to ground before you probe the CAN bus. Third: the cockpit multi vision supply circuit (page 3) – that unit draws enough current to drop voltage across a corroded connector. Check for 12.6V at the multi vision input before blaming the display. These are the kind of details you only get from the OEM drawing.

Related manuals you might need: FAUN Circuit and Piping Diagrams Superstructure Part D2 covers the crane-side electrical and hydraulic interlocks. FAUN Part E Crane Testing Instructions gives you the load test procedures. And if you want the full operator-level data, Tadano FAUN ATF 80-4 2002 Operators Manual – 779 Pages of Factory Data is worth having on the shelf.

For background on why OEM schematics matter more than aftermarket, read up on Automotive Wiring standards or check the Automotive Industry Overview for regulatory context. But honestly, the best education is getting your hands on the real factory print.

Does this schematic cover the engine control system?

Yes. Page 2 includes the adaptation module for engine control, the diagnostic controller, and the relay for engine stall. You can trace the electronic system from the ECM output to the injectors if needed.

Are the torque specs for electrical connections included?

No. This is an electrical schematic document, not a service manual. Torque values for terminal studs are found in the FAUN 214 service manual (sold separately).

Can I use this PDF on a tablet in the shop?

Yes. The pages are scanned at high resolution – you can zoom into any relay designation or wire gauge label. Keep a paper copy too; grease and screens don’t mix.

What if I find a component not listed in the index?

Every component appears in the circuit block diagrams. If you cannot locate a relay, check the slipring chassis/crane interface – some ancillary circuits are switched through that junction. Contact us if you’re stuck; we can confirm the document version.

You need the real OEM data to keep a FAUN 214 running safely. Don’t waste billable hours on a generic schematic that has the wrong pinout. Access the Factory Manual now – 49 pages, no reprint, just the original diagrams Tadano FAUN issued for the chassis.
