Product Overview
The WL01-18-300 is a Mazda OE-spec replacement alternator delivering 12V output at 80A with a 2PK double-groove V-belt pulley, engineered for Mazda BT-50 and Ford Ranger pickup trucks built on the shared platform. This brand-new aftermarket unit, identified by the A002TA6099 and A2TA6099 cross numbers, matches the original charging-system specification of these pickup platforms.
Fitted with internal regulator design, this alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 80-amp rating supports the standard electrical load of these pickups, including lighting, ignition, climate control, powered accessories and battery charging.
Key physical specs: net weight 5.7 kg, gross weight 6.0 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.
The Mazda BT-50 / Ford Ranger Pickup Platform and 80A Charging System
Mazda BT-50 and Ford Ranger pickup trucks on the shared ladder-frame platform rely on a compact alternator with a double-groove V-belt drive. The 80A output supports the standard electrical equipment of these commercial-grade pickups including diesel glow-plug operation on the WL engine family.
This unit is specified as 12V 80A, matching the factory charging-system specification of these platforms. The 2PK double-groove pulley matches the original V-belt layout. Never replace a double-groove pulley unit with a 1PK, 4PK, 6PK or 7PK unit: the belt layouts are not interchangeable, and the wrong pulley will cause belt mis-tracking, slipping and charging faults. Always cross-check against your old alternator before ordering.

Engine Compatibility and Cross Reference
This alternator fits the following vehicles. 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.
| Vehicle | Engine | Notes |
|---|---|---|
| Mazda BT-50 | Verify engine code (WL series diesel) | Verify 2PK, 80A and mounting layout |
| Ford Ranger | Verify engine code (shared platform) | Verify 2PK, 80A and mounting layout |
Multiple Mazda, Ford, 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, WL01-18-300 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. Confirm the pulley: this unit uses a 2PK double-groove V-belt pulley. Units with 1PK, 4PK, 6PK or 7PK pulleys are not interchangeable with this drive layout.
3. Confirm the exact model (BT-50 or Ranger), engine code 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 5.7 kg net; significant weight difference indicates wrong assembly.

FAQ
Q: Which vehicles does this alternator fit?
A: It fits Mazda BT-50 and Ford Ranger pickups on the shared platform. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.
Q: Is this alternator 2PK or multi-rib?
A: This unit uses a 2PK double-groove V-belt pulley. Multi-rib pulley units are not interchangeable with this drive layout.
Q: My old alternator shows OE number A002TA6099 or LR190-731, will WL01-18-300 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 A2T-series cross numbers identify this as a Denso-pattern unit matching the Mazda/Ford 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 BT-50 / Ford Ranger pickups: 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. Confirm the double-groove V-belt is correctly seated in both pulley grooves and 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.
