The Mazda Verisa ZY-VE Platform and 80A Charging System

The Mazda Verisa is a compact passenger car powered by the ZY-VE 1.5-litre DOHC engine. This alternator with a 6-rib (6PK) accessory-belt drive delivers 80A, matching the factory charging-system specification of the platform and supporting the standard electrical equipment including lighting, ignition, climate control and battery charging.

This unit is specified as 12V 80A. The 6PK pulley matches the original accessory-belt layout. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and charging faults. Never substitute a 1PK, 2PK, 4PK or 7PK unit for this 6PK drive layout. Always cross-check against your old alternator before ordering.

Technical Specifications

Engine Compatibility and Cross Reference

This alternator fits the following vehicle. Do not rely solely on the model name for fitment validation; always verify engine code, production year, old-part OE number, pulley type and amp label on your original alternator.

Multiple Mazda, Denso and supplier OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, ZJ1018300B serves as a direct drop-in replacement.

What to Look for in a Replacement

Follow these five verification steps before placing your order to avoid wrong-part returns:

• 1. Check the amperage label on your old alternator: confirm it is rated for 80A. Different amp ratings are not interchangeable.

• 2. Count pulley ribs: this unit requires 6PK (6-rib). Units with a different rib count are incompatible for this accessory drive setup.

• 3. Confirm the exact model (Mazda Verisa), engine code (ZY-VE 1.5L) and production year of your vehicle.

• 4. Match against OE / reference part numbers stamped on your original housing.

• 5. Weight cross-check: genuine matching unit weighs approximately 5.05 kg net; significant weight difference indicates wrong assembly.

Application Scenarios

• Independent repair shops and Mazda specialists servicing the Verisa compact platform across Japan, Asia-Pacific, the Middle East, Africa, Europe and Latin-America.

• Parts counters and jobbers stocking Japanese compact car charging-system components.

• Owners maintaining original-spec Mazda Verisa charging systems.

• Fleet and rental workshops maintaining compact Japanese fleets.

• Used-car export traders supplying pre-owned Japanese compact cars to global secondary markets.

FAQ

Q: Which vehicles does this alternator fit?
A: It fits the Mazda Verisa with the ZY-VE 1.5-litre engine. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.

Q: Is this alternator 6PK?
A: Yes. This unit uses a 6-rib (6PK) pulley. Confirm the rib count on your old alternator before ordering.

Q: My old alternator shows OE number A3TG2881 or A002TC0091, will ZJ1018300B work?
A: Yes. These numbers belong to the same alternator family, differing only by production revision and market specification. It serves as a direct replacement.

Q: Is this a Denso-pattern alternator?
A: Yes. The A3T/A2T-series cross numbers identify this as a Denso-pattern unit matching the Mazda OE specification.

Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, wrong belt tension, or vehicle-wiring faults.

In Practice

For technicians working on Mazda Verisa vehicles: Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work.

Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to Mazda workshop-manual specifications.

Inexperienced mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or vehicle electrical components.
