Customer Reviews
Very satisfied with the product
Thank you for your positive review! We are glad to hear that you are satisfied with the ARCO Zeus A275L Alternator. Please don't hesitate to reach out if you have any further questions or concerns. Thank you for choosing our product!
Arco A 275 alternator is almost a perfect fit on a yanmar 4jh3e. Installed with balmar pulley kit . Easy install and fast charging .n more belt dust covering everything.
Installed A275L on a Yanmar 4JH3E without problems. The B+ post is removable to allow for fit under the heat exchanger. I already had a Serpentine kit (J10).
I'm using our existing Balmar regulator, hope to upgrade later to Zues reg later.
Using Balmar's belt manager I crimp it to ~150A, steady around 1250 engine RPM, 300 Alt.
Had a great experience ordering from The Yacht Rigger, they were able to accommodate to my travel schedule.
Great customer service!
