Balmar AT Series 200A Alternator Repair Kit

Description

The Balmar Offshore Repair Kit for AT Series 200A 12V alternators provides the core internal service components most likely to be needed when maintaining or repairing a high-output alternator away from normal parts support. For long-distance cruising and offshore vessels, carrying repair parts onboard can reduce the risk that an alternator failure leaves the boat without a primary charging source.

The kit includes replacement bearings, brushes, and a rectifier. Bearings support the rotating assembly and can become noisy or develop play after extended service. Brushes transfer field current into the rotor and are normal wear components. The rectifier converts alternator output into DC current for the battery system and is a critical component in the charging path.

Because the kit is intended specifically for Balmar AT Series 12V 200A alternators, compatibility should be confirmed before relying on it as an onboard spare. Alternator disassembly and repair require appropriate tools and electrical/mechanical skill, so the kit is best suited to experienced owners, marine electricians, and service technicians.

For offshore boats where replacement alternators may not be immediately available, carrying the principal wear and rectification components can provide an additional level of charging-system preparedness. Take a look through our alternator parts & accessories.
