Charging System


Omega $575.00

400 Watts. Light and Heat for 1970-95 Boxers.

Omega. The end. The end of that greatest limitation of the air cooled Boxer, a small capacity charging system. Now, from Motorrad Elektrik, the Omega alternator kit for all 1970 through 1995 2-valve BMW twins.

 

Omega produces 400 watts of power at much lower engine speeds than before. Serious charging starts at 2000 RPM, and max output is achieved at 4000 RPM (which was the onset of actual battery charging in the original system!) Installation of extra lighting or heated gear is no problem instead of an invitation to chronic undercharging and battery problems.

This is a complete alternator kit, comprised of rotor, stator, hi-output voltage regulator, high-capacity diode board with solid mounts, connecting wires, allen wrench and a rotor removal tool. All parts are of new manufacture so no trade-ins are required, but the original aluminum stator cover with brush holder from your alternator must be reused . This requires soldering 3 connections on the front, which we'll be glad to do for you free upon request. The rest of the installation is as simple as removing the original parts and bolting on the Omega parts. On most models, total installation time is 2 hours, give or take.

No Trade In required, but you will need the original Stator housing with brushes. As always, call if you have questions.

Complete Omega kit, ready to install: $575.00 plus shipping

/5 Installation requirements...

Please note that installation of this kit on a 1970-73 model /5 requires the use of a stator housing used on all 1974 through 1995 models. This is the round aluminum cover with the brush holder mounted on it, held to the engine with 3 allen screws.

The stator windings supplied with the Omega kit are larger in diameter than the original /5 part, and will not fit . The /6 - later stator housing should be readily available from any number of used parts vendors, and the original /5 brush holder assembly can be reused.

Also, if additional accessories such as lights or heated gear are to be used, it is strongly recommended that a ventilated front engine cover from a 1974 through 1978 model be used to prevent possible overheating of the new alternator parts.

The original /5 front cover has almost no ventilation for cooling air to enter the front of the engine. This part should also be readily available used for a nominal amount .

 


200 Watt Alternator Kit for '55-'69 Boxers $575

This 200 watt, 12 volt alternator conversion is a completely self-contained unit, with the regulator and diode board built in -
everything fits neatly under the front cover. The entire alternator attaches to the engine with two bolts which screw into existing tapped holes. Only three wires need to be connected to the original harness, and then replace the bulbs and battery - it's that simple. Real juice for your R60/2 or R69S! The kit comes complete with rotor puller tool, allen wrenches, fasteners and wire terminals, bulbs, and battery. Think! Real power for heated grips, electric vest, GPS...

High Output Alternator Conversion for /5 Boxers $200.00

Higher Output Alternator for /5-The 70 through 73 models have a 180 watt charging system and a small 18 amp-hour battery that has a hard time staying charged. To get the same 280 watt output that later boxers have, the stator is rewound and used with a new Omega diode board. Your stator is returned ready to install, with a new diode board. The supplied Omega diode board, is the same one as supplied with the 400 watt Omega alternator for Airheads.

 

Omega Diode Board $90

Heavy duty high voltage automotive diodes in a large heat sink on a high temperature printed circuit board - what this means for you is consistent charging, long life, and a minimum of fuss.

Kit includes new wires and fasteners. Easy replacement for factory part.

 

Solid Mount Kit for Diode Board $20.00

This solid mount kit ends once and for all the problems associated with rubber mounts - poor charging due to marginal grounds and heat retention in the diode board. Torn mounts can allow the board to short out against the front cover. Kit has four hexagonal aluminum spacers with permanent studs.

 

 

New Rotor $100.00 (no exchange required)

These are very high quality rotors, NEW, not remanufactured, European made to exacting quality standards . They will fit and work perfectly in all models from 1970 onward, with no need to return the old part .

 

 

Remanufactured Rotor $90.00 (exchange only)

Remanufactured to better than original specs with high strength resin, pure copper wire and high temperature nylon insulators. Full one year warranty. Core required first - send it in and we'll send you a remanufactured rotor immediately.

 

Remanufactured Stator $75.00 (exchange only)

Stators rarely fail, but if they do our remanufactured units will provide a very durable, cost-effective solution. Highest quality copper is used for the windings, along with modern high-strength resins and nylon insulators.

 

Solid State High Output Voltage Regulators $32.00

Higher Voltage Regulator, $32.00 : This is a solid-state, non-adjustable voltage regulator that will help the battery recover more quickly from the heavy discharge of a startup, or a few minutes of low-speed running. The regulator DOES NOT INCREASE CHARGING SYSTEM OUTPUT CAPACITY ! No regulator alone can. It does maintain the battery at a higher 14.2 voltage than the stock regulator allows, which is closer to the designed best operating voltage of the entire electrical system and gives more reserve in the battery. There are no moving parts internally, and it's a simple bolt-on, plug and play install.
