A Kobelco that will not charge or will not crank is not making money, and unlike most hydraulic faults, the operator cannot even limp back to the yard. Charging and starting failures are therefore the electrical faults we are asked about most urgently — and they are also the category where identification mistakes are most common, because the same machine model was fitted with different alternator and starter families across its production run. Guangzhou Shenyue Machinery Technology Co., Ltd. handles several of these units every week, and this guide sets out how to identify what you have and order the right replacement the first time.
Why the plate matters more than the model
An SK200-8 carries a Hino J05E engine, and the alternator and starter are engine-driven components with their own manufacturers and part families. Across the production years of the SK-8 generation, units from different suppliers were fitted, and a machine that has had an engine exchange or an electrical repair may no longer match its build-year catalogue. The component nameplate — stamped with the unit's own model and serial — is the only reliable identifier. A photograph of the plate, plus the machine serial, lets us quote in hours instead of starting a chain of questions.
The units we commonly quote
| Component | Commonly quoted references | Note |
|---|---|---|
| Alternator | A3TN5188RQ / VAME017614 | Stocked example; confirm by plate |
| Alternator | VA32G6800100 | Stocked example; confirm by plate |
| Alternator | VH270402500A | Stocked example; confirm by plate |
| Starter | By plate only | Multiple families across the run |
The alternator references above are live rows from our own stock list, quoted as commonly quoted — the machine serial and the unit plate settle which one applies. Starters vary more between build years, so we quote them strictly from the plate.
The Mitsubishi Electric distinction
Many charging and starting units on Japanese excavators carry the Mitsubishi Electric name. Buyers sometimes assume this falls under our Mitsubishi authorization, and it does not: the formal authorization held by Guangzhou Shenyue Machinery Technology Co., Ltd. covers Mitsubishi Heavy Industries engine parts — the 6D34, 6D31 and 6D24 families — while Mitsubishi Electric is a separate company and its starters and alternators sit outside that authorization. We supply these units through original supply channels as genuine parts, or as clearly identified quality replacements, and the grade is marked on every quotation line.
What usually fails
On alternators the pattern is bearings and rectifiers: a whining noise that rises with rpm, or a charging light that flickers at idle and clears with revs, points to wear well before the unit dies outright. On starters, the classic sequence is a gradual lengthening of cranking time, then a clicking solenoid with no cranking. Both categories reward early replacement — an alternator that sheds a bearing at sea on the way to a dredging site is a far more expensive event than a scheduled swap.
Grades and how we supply
Genuine units through original supply channels, OEM-quality replacements and clearly identified aftermarket units are quoted on separate lines. For charging and starting parts the sensible grade often depends on machine age and duty: a new-generation machine working contract hours justifies genuine, while a ten-year-old unit on intermittent duty is well served by a quality replacement. Guangzhou Shenyue Machinery Technology Co., Ltd. has specialised in Kobelco parts since 2007, with 4 warehouses over 1000 m² in Guangzhou, 3,000+ part types on the shelf and 100,000+ part numbers available to order through original supply channels. Shenyue is an independent supplier and is not an authorized dealer of Kobelco Construction Machinery Co., Ltd.; for Kobelco, Hino, Isuzu, Yanmar, Cummins, Kawasaki, Nabtesco, KYB and KPM we supply genuine parts ordered through original supply channels alongside quality replacement alternatives, at prices close to agent level, and our five formally authorized brands — Mitsubishi, Garrett, TONGMYUNG, Marusan and NIKURA — are named on every quotation.

Frequently Asked Questions
Which alternator fits my SK200-8?
The unit is decided by the plate on the alternator itself, not the machine model — different families were fitted across the production run. Send a photograph of the plate plus the machine serial, and Guangzhou Shenyue Machinery Technology Co., Ltd. will confirm which of the commonly quoted references, such as A3TN5188RQ / VAME017614 or VH270402500A, applies.
Is the Mitsubishi alternator covered by your Mitsubishi authorization?
No, and we state this plainly: our formal authorization covers Mitsubishi Heavy Industries engine parts such as the 6D34 family. Alternators and starters carry the Mitsubishi Electric name, which is a different company. We supply them through original supply channels as genuine units or clearly identified replacements.
Genuine or replacement — which grade should I choose?
For a machine on contract hours, genuine through original supply channels is the safe default. For an older machine on intermittent duty, an OEM-quality replacement marked clearly on the quotation is the sensible middle path. We quote every grade on separate lines so the choice stays with the buyer.
How fast can a starter or alternator ship?
Stocked units can be photographed, packed and dispatched within days of a confirmed order, and the quotation normally comes back within 24 hours of a complete enquiry. Consolidation with the rest of your parts order into one shipment is standard practice at Guangzhou Shenyue Machinery Technology Co., Ltd.
