IMPORTANT: All CMI Alternators are custom and may require a 3-4 week lead time.
is the first and only Leece-Neville / Motorola case alternator I know of that is
available & already set up for external regulation. What sets this alternator apart from an off the shelf unit are the components chosen to upgrade, tweak it and make it ready for installation. The alternator includes a billet machined 3/8" belt pulley, upgraded brush assembly, external regulation conversion and a spacer/bushing so it can fit either 1" or 2" mounts.
I can package this alternator with either a Balmar MC-614H or ARS-5H regulator. I recommend setting the Belt Manager feature to level three or four when setting up the regulator. It is also mandatory that an alternator temp sensor be used. I only recommend using Balmar regulators with this alternator.
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 medium duty 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 alternator (see my other alternator offerings) and the
factory alternator. It was designed to meet a price and performance
niche not available to boaters previously. This is a what I consider a
medium/light duty alternator intended for smaller banks that just need
healthier charging profile. It is not intended to drive large AGM banks,
large flooded banks or large GEL banks. See my other alternator
offerings for this type of use.
The CMI-105-ER comes standard with a tachometer output studs (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.
