Q 1. What does the WAI 10943N replace — which Iseki part numbers does it cover?

A. The WAI 10943N replaces Iseki original-equipment alternator numbers 6281-200-032, 6281-200-032-10, 6281200032, and 628120003210, as well as the Kokusan Denki reference GP9914 — five cross-references in total. If you are working from a different number or a parts manual reference, search our cross-referenced catalogue by OEM number to confirm the match, or ask Simon.

Q 2. Is this a genuine Kokusan Denki alternator or an aftermarket unit?

A. The 10943N is a brand-new WAI-supplied alternator built to the Kokusan Denki PMA specification. It is not a reconditioned or remanufactured unit. WAI is a specialist in alternator and starter motor replacement parts.

Q 3. What does PMA mean, and does it matter for my application?

A. PMA stands for Permanent Magnet Alternator. Unlike a conventional wound-field alternator, a PMA uses a permanent magnet rotor and does not require an external field excitation circuit. This design is characteristic of the original Kokusan Denki unit this part replaces. Confirm your existing alternator carries the same design before fitting.

Q 4. Does it matter which direction the engine drives the alternator?

A. No — the WAI 10943N supports bi-directional rotation, so it is compatible with installations where the drive belt or direct drive runs in either direction. The pulley is a groove type; confirm the groove profile matches your existing drive arrangement.

Q 5. Which machines or vehicles will this alternator fit?

A. Specific vehicle or machine fitment data is not published for this part. The best route is to match by OE part number — this unit covers Iseki references 6281-200-032, 6281-200-032-10, 6281200032, 628120003210 and Kokusan Denki GP9914. Search our catalogue by your OEM number, or ask Simon to confirm suitability for your machine.

Q 6. How do I confirm this part fits my vehicle or machine?

A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.

Q 7. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
