FOR SALE: 105A Alternator -Westerbeke/Universal Fit
Placed by Maine Sail on 03-21-2018
Location: Portland, ME USA
A customer cancelled on this brand new Compass Marine externally regulated Leece-Neville (Motorola / Prestolite fitment) alternator. His loss could be your gain.
This is the first and only Leece-Neville / Motorola case alternator I know of that is available and already set up for external regulation. What sets this alternator apart from an off the shelf unit are the components chosen to assemble, upgrade, tweak it and make it ready for installation.
This alternator includes a billet machined 3/8 belt pulley, upgraded brush assembly, external regulation conversion kit and the Leece-Neville special spacer/bushing kit so it can fit either 1 or 2 mounts.
None of these items come standard on this type of alternator and all are added by Compass Marine in order to offer a ready to run unit. Even if you were to source the parts and build this alternator yourself you cant even buy the parts for this price!
This is not a cheaply built re-badged automotive alternator with a dumb internal regulator. This is a marine alternator, spark protected with a single 1 or 2 foot. The 1 to 2 spacer is included and is a $26.00 accessory! This 105A externally regulated alternator intended to replace the stock alternators found on many Westerbeke or Universal diesel engines. It will fit any engine that uses an 8MR style alternator.
This alternator fills the gap between a true high performance/high price alternator and a cheap stock alternator.. It was designed to meet a price and performance niche not available to boaters previously.
The CMI-105-ER comes standard with tachometer sense (stator tap) for diesels that run the tachometer sense off the alternator. Not all engines drive the tachometer from the alternator, but most Westerbeke and Universal engines do. The CMI-105-ER is set up for external regulation only. It has no internal regulator. You will need an external regulator to install this alternator.
Intended to fit many Universal and Westerbeke diesels that use an 8MR Leece-Neville
105A cold rated, with good high idle performance.
Machine wound stator of 14GA top quality magnet wire means better cooling and higher temperature tolerance.
Precision machined rotor and slip rings for greater contact at all RPM.
High performance diode rack.
Billet Machined Steel Pulley - 2.6 Diameter X 3/8 or 10mm Belt
Brushes are high copper content not run of the mill carbon brushes. This yields superior conductivity and considerably longer brush life.
Ready to accept an external regulator (I recommend only Balmar regulators).
Isolated ground for steel or aluminum boats or for using a shunt in the negative path..
Hand assembled and built by Compass Marine in Maine, USA
