- Action: To Do List item A0122 – Obtain replacement engine alternator.
- Completed: 27 August 2016
- Cost: $1889.17
As the existing Balmar Series-6 100 amp alternator was severely corroded and it was still unknown if a reliable repair or refurbishment could be accomplished, we decided a replacement alternator was needed. As the Balmar alternator brand had a very good reputation due to reviews posted on the internet, we decided to stay with this company. We selected a Balmar 60-YP-MC-150-J10 kit, which includes a Series-6 150 amp alternator with J10 serpentine pulley, a MC-614 Regulator, temperature sensors, and mounting hardware.
The selection of the J10 serpentine pulley was preferred over dual V-belts due to projected reliability and longevity of a 10-groove serpentine belt. The selection of the J10 serpentine pulley for the alternator also meant we would need to upgrade the single V-pulleys for the water pump and engine crankshaft pulley. For this we selected an Electromaax Yanmar Marine 4JH5-E Serpentine Pulley Kit (PK-4JH5 ) with an optional belt tensioner.
The items were ordered and received 27 August 2016. The cost is listed below.
