New Holland Kobelco CKE1350, CK1600 2004 Workshop Manual

You’ve got a CKE1350 or CK1600 that’s dead in the yard because a harness shorted somewhere in the revolving frame. Or the pressure switch for free fall control isn’t talking to the relay box. Without the factory wiring diagram, you’re chasing ghosts with a test light. That’s exactly why this New Holland Kobelco CKE1350, CK1600 2004 Workshop Manual exists. 59 pages, all dedicated to the electrical system – no engine overhaul, no hydraulic circuits, just the wires, connectors, and components that make the machine run. I’ve been turning wrenches long enough to know that generic aftermarket diagrams will leave you with a blown fuse and a headache. This is the real deal from New Holland Kobelco.

Electrical Wiring Schematic: Factory Routing

Section 1 of the manual lays out the full electrical wiring schematic for both the CKE1350 and CK1600. This isn’t a simplified cartoon – it’s the exact drawing KOBELCO used on the assembly line. You’ll see each wire gauge, connector pin location, and circuit path. Need to trace the power feed to the wiper control relay (PN 2479R1366)? It’s on page 1 of the schematic. The manual expects you to use a multitester and follow the procedure on page 2: shut off the power before unplugging any connector, and never push a probe into the female socket on a round waterproof connector. I’ve seen a guy blow a $400 controller that way. Don’t be that guy.

Arrangement of Electrical Parts – From Cab to Left Guard

Chapter 2 breaks down every electrical component by physical location. There are six sub-sections: Cab, Right Deck, Floor Plate and Left Stand Panel, Revolving Frame, Left Deck, and Left Guard. If you’re trying to find the relay box (JJ24E00016F1) or the fuse box (GG73E00003F1), the manual shows you exactly which bracket it bolts to and what the harness routing looks like. The arrangement drawings include part numbers and connector views. This is the kind of detail that saves you from removing a whole panel to find a relay that’s actually sitting behind the left guard. For a DIYer working in a home garage, these location diagrams are worth the price of the manual alone.

Component Specifications: Fuse Box, Relay Box, Pressure Switches

Chapter 3 is a catalog of individual electrical parts with specs. The fuse box (GG73E00003F1) gets a full page: fuse ratings, cavity assignments, and the exact replacement part number. The pressure switch for control pressure cut and free fall (GG50S00006P1) is covered in section 3.4 – you get the switch opening pressure and the connector type. The relay box (JJ24E00016F1) includes internal circuit diagrams so you can bench-test each relay. If you’re troubleshooting a swing flasher that won’t flash, section 3.3 gives you the relay pinout and how to check it. This manual doesn’t waste space on theory; it tells you what to probe and what reading to expect.

Troubleshooting the Exhaust Gas Secondary Regulation Engine

Chapter 4 is the diagnostic section for the engine control system – specifically the exhaust gas secondary regulation (EGR) setup on these machines. It covers the diagnostic function (4.1), how to find faulty locations using the blink codes (4.2), clearing fault data (4.3), and checking the blown‑off diagnosis lamps (4.4). There’s also the system configuration (4.5), fuel injection control (4.6), calculation of accelerator opening (4.7), and specifications of input and output (4.8). If your CKE1350 is throwing a code for the accelerator position sensor, section 4.7 walks you through the voltage range calibration. Factory logic, not guesswork.

3 Reasons to Reach for This Manual Instead of Aftermarket

First, the wiring schematic is drawn to the OEM connector numbering – not some generic color-code that matches nothing. Second, the component locations are verified against the actual machine layout; aftermarket books often use a “typical” diagram that doesn’t account for the left stand panel differences between the CKE1350 and CK1600. Third, the troubleshooting tree in chapter 4 was written by KOBELCO engineers who know the specific failure modes of the 2004 engine control. You won’t find that data in a third-party manual. If you need to work on other equipment, AutoRepairManuals also carries Manual Transmission repair documents for trucks and other gear – but for this excavator, stick with the factory source. And for those who also run a service truck, check out Manual Transmission coverage for the powertrain side.

Does This Manual Cover the Entire Machine?

No. This 59-page document is strictly the electrical system – wiring, components, and engine control diagnostics. It does not cover the undercarriage, hydraulics, or engine mechanicals. If you need torque values for track bolts or cylinder head specs, you’ll need the full workshop manual. But for electrical fault finding, this is the only document you should trust. The manual is dated 2004 and applies to both the CKE1350 and CK1600 models. Pay attention to the caution notes on page 2: when working with round waterproof connectors, never insert the multitester probe into the female side. Use the male pins or a breakout harness. That single note has saved me from having to replace a harness.

Source Validity: OEM Factory Print, Not a Reprint

What you’re getting here is the original PDF scanned from the official KOBELCO shop manual. The book code is S5GN1902E①. There are no watermarks, missing pages, or third-party annotations. Every page matches the factory binder – including the caution page and the table of contents that lists “ELECTRIL SYSTEM (COVER)” (yes, that’s the original spelling). If you’ve been burned by aftermarket manuals that say “refer to the dealer for wiring diagrams”, this is the opposite. The diagrams are complete and legible. Access it, print section 1, and tape it to your toolbox cover. You’ll be glad you did when the customer asks why the boom won’t lower.

Q: Can I use this manual for a CK1600 that was built in 2005?

Only if your machine’s electrical system hasn’t been updated. The manual covers the 2004 model year. New Holland Kobelco made some harness revisions in late 2005, so the wiring colors and connector locations may differ. Compare your serial number to the range listed in the manual introduction (not included in this scan) – if they match, the diagram is accurate. Otherwise, find a manual that matches your build date.

Q: Does this manual include torque specs?

No. It’s the electrical shop manual only. Torque values for fasteners are in the main machine workshop manual.

Stop wasting time with aftermarket diagrams that skip details. Access the Factory Manual for your New Holland Kobelco CKE1350 or CK1600 and get back to turning bolts. Your test light and multimeter will thank you.
