Here is a description of the alternator for the Daihatsu Gran Max 1.5 (with the 3SZ‑VE engine) — useful if you’re looking to replace or check the unit.

Key specifications

• Voltage: 12 V.  
• Output/Amperage: Around 85 A in one listing. 
  
• Another listing shows 80 A for model 27070-BZ202.  
• 
  
• Pulley/belt type: ''6 PK'' (i.e., 6-rib serpentine belt) pulleys for some units.  
• Plug/socket type: 4-pin in one listing.  
• Compatible part numbers: e.g., 27060-BZ290, 27060-BZ202, 27060-BZ201.  

What to check/consider

• Ensure the alternator is 12 V — consistent with the vehicle’s electrical system.
• Confirm amperage rating (85 A vs 80 A) — higher load demands (accessories, lights, A/C) might benefit from the higher output version.
• Belt/pulley compatibility: Since it mentions 6 PK belt type in some variants, check your current belt setup.
• Electrical plug connector: Make sure the 4-pin socket matches your wiring.
• Physical mounting and bracket fitment: Even if part numbers match, check mounting holes & clearance.
• Warranty and condition: Many aftermarket units mention a 6-month warranty in listings.
