                  Balmar 70A, 6-Series Light Duty Alternators are designed for recreational marine applications and are engineered to replace most OEM alternators on a wide variety of marine gasoline and diesel engines. These alternators deliver high-output performance in a compact, small-case package and are available in common mounting configurations.


                  • Designed for recreational marine applications
                  • Ideal for modest charging upgrades
                  • Generates 70 amps
                  • Dual fan cooling
                  • High airflow frame
                  • Maximum RPM: 12,000
                  • Recommended for use with Balmar multi-stage voltage regulators (Sold with alternators in kits or separately)
                  • Engineered to replace most OEM alternators on a wide variety of marine gasoline and diesel engines
                  • Available in (3) mounting configurations
                    • Saddle Mount: 3.15" (Typical of Yanmar engines)
                    • Single Foot Mount: Convertible to support 1" Motorola and 2" Delco style mounting configurations
                    • J-180 Mount: 4"

                  Balmar Smart Ready Technology:

                  • Internal Regulation is a feature unique to the 6-Series alternator
                  • Enables the alternator to be used with smart Balmar external regulation, or as a stand-alone, internally regulated alternator system
                  • Fixed, 14.1-volt charge controller is ideal as a built-in back-up regulator for the cruiser, or as a full-time regulator for systems where smart, multi-stage regulation is not required
                  • If battery loads are relatively small and your engine is running frequently, the alternator's internal regulator may be sufficient to support your electrical needs without external regulation
                  • If your vessel utilizes larger deep-cycle battery banks or the engine's duty cycle is less frequent (as is the case in most sailing applications), the 6-Series Alternator combines and works seamlessly with Balmar's ARS-5Vage Regulator or Max Charge Voltage Regulator
                  • USCG Title 33, ISO, SAE and CE Compliant

                  Pulley Designations:

                  • "SV" = 1/2" Single Pulley
                  • "DV" = 1/2" Dual Vee
                  • "K6" = K-6 Serpentine
                  • "J10" = J-10 AltMount® Serpentine

                  The selection process includes the following steps:

                  • Step 1: Determine your vessel's electrical load
                  • Step 2: Identify your existing battery bank technology and capacity
                  • Step 3: Select your optimum alternator output
                  • Step 4: Identify the alternator mounting style present on your engine
                  • Step 5: Determine your belt and pulley requirements
                  • Step 6: Select additional charging system options


                  • Balmar's 1/2" Deep Vee Pulleys (single and dual) can accept a 3/8" and 7/16" belts
                  • Image is for reference only, actual product may vary

                  Rated 5 out of 5 by from Great alternator. Just started the motor after 4 years of inactivity and the new alternator works great!

                  Most importantly what is the rmp output curve ? Diesels run 1500 to 1800 rpms. Many of not most diesel boats are twin engine. how best are the alternators regulated ?

                  Asked by: jack Offski
                  Please see the attached image with the output curves. Balmar has great multi stage regulators. This item number only includes the alternator but we do sell the regulators separately or in kits that include the alternator, regulator, temperature sensors and mounting hardware.
