The Arco 4401 - 24 volt alternator model uses a DF315 (3.15" Dual Foot Saddle Mount) with isolated ground only, making it suitable for replacing small-case alternators like Hitachi, Lucas, or Mitsubishi styles, particularly on most Yanmar engines. This isolated ground setup ensures compatibility with external regulation and prevents ground loops in sensitive electrical systems.
