Balmar XT Series Dual Foot Marine Alternator

Balmar is replacing the AT-Series alternator family with its XT-Series products. The XT-Series is drop-in compatible with the AT-Series and it provides slightly better performance than the AT-Series. Balmar XT-Series alternators provide maximum charging power in a small case package, suitable for installation in most small-to-medium sized diesel engines and most GM-based 4.3 liter to 8.1 liter gasoline engines.

Features:

• 12V DC
• 170 Amps in a small case package
• Provides up to 140 amps at idle speeds
• Designed for recreational marine applications
• Engineered to replace most OEM alternators
• Multiple pulley types available
• Ideal for modest charging upgrades
• State-of-the-art, braided stator wire design to generate exceptional output in the smallest possible area
• Operates 5°-10° C cooler than AT-Series
• May require a Tachometer Signal Stabilizer (Part No. 15-TSS; Sold separately) if your current tach is not adjustable
• Should only be used in Dual Vee or Multi-groove serpentine belt configurations
• AltMount® Serpentine Pulley Conversion Kits support all XT-Series alternators
• Smart Ready® internal regulator technology provides an additional level of fault tolerance for cruising boaters
• Dual fan cooling
• High airflow frame
• Ideal for large battery banks
• Approvals: USCG Title 33, CE, ISO 8846 and SAE J1171 certified

Note: Regulator, battery/alternator temp sensors & harness are sold separately.

Pulley Designations:

• "DV" = 1/2" Dual Vee
• "K6" = K6 Serpentine
• "J10" = J10 Serpentine

The selection process includes the following steps:
