The Ultimate Motorsport Alternator

RED Winches is proud to offer the next development in motorsport charging systems, the Mechman Alternator

These range of Alternators can now provide your truck / buggy / vehicle with enough charging power for all your high performance winching needs.

This alternator supplies a 12v charge to your vehicle system up to 320A

This alternator offers large case alternator performance in a compact package.

Highly efficient, these 6 phase alternators use less horsepower per Kilowatt than conventional 3 phase alternators.

12 press fit diodes, twin rectifier plates, and highly efficient twin internal cooling fans make them durable in any application.

Smaller, lighter rotors and reduced rotating resistance make them an excellent choice for high RPM or racing applications.  

These Alternators have hairpin stators and high pole count rotors that create much less Electromagnetic noise than conventional 3 phase alternators.

Note: To prevent under or over speeding the alternator, always be sure correct alternator pulley diameter is used in high RPM or racing applications.

Its a One Wire Regulator

RED Winch alternators are "one wire" or "self exciting" regulators that do not require an alternator plug to be used for the alternator to function.

RED Winch one wire alternators have the lowest turn on RPM of all motorsport alternators, and do not require revving of the engine in order for the alternator to begin charging.

Belt Slip

One of the most common problems effecting custom built vehicles is belt slip.

This 320 amp version may cause belt slip on vehicles with poor alternator pulley belt wrap, or with narrower than 6 groove serpentine drive belts on a 50mm pulley.

As high performance twin motor winches increase the amount of current required from the batteries / alternator, the strain against the alternator drive belt is also increased.

A high output alternator like this one if driven by a single V belt will commonly begin to slip on the alternator pulley, this is why a double pulley is offered with this unit.

4 groove serpentine belt driven alternators may also experience belt slip so as mentioned a 6 groove belt or higher is recommended

If belt slip becomes an issue, a free spinning backside idler pulley must be mounted next to the alternator pulley to force the alternator drive belt to wrap further around the alternator pulley, increasing contact surface area, and drive belt tension at the same time.

RED Winches recomends at least a 150 degree belt wrap on the alternator, ideallly you should aim for as close to 180 degrees or better.

Performance

The output curve shown in one of the images posted assumes that the crankshaft pulley is at least 3 times the diameter of the alternator pulley, meaning that the alternator is spinning 3 times faster than the engine.

In high RPM racing applications, a less than 3:1 ratio may be desired to prevent the alternator from exceeding it's maximum recommended operating RPM of 20,000 RPM. When ordered the supplied pulley diameter is 50mm

Several different alternator pulley diameters are available, be sure to consult with RED Winches if you are unsure which diamter to use.

Cabling

Using the properly sized alternator charge cables is absolutely necessary for proper charging system performance.

Using alternator charge or ground cables that are too small for the amount of current that the alternator produces may restrict alternator current flow, and in extreme cases, could cause a fire.

It is perfectly acceptable to leave smaller OEM charge and ground cables in place, as long as properly sized supplemental cables are added for positive and ground connections, running directly from the alternator housing to the positive and negative terminals of the battery.

Ideally for this alternator a high capacity copper cable of 8mm in diameter or with a 38mm2 cross sectional area should be used.

Warranty

All RED Winch alternators are backed by a 2 year performance guarantee against manufacturers defect.

Within the 2 year warranty period, any RED Winch alternator can be sent back to the manufacturer for dyno testing and re-certification of output at no cost to the customer.

If for any reason a RED Winch unit does not meet it's original advertised output specifications, it will be serviced to like-new performance for no additional charge.

Affordable freshen-up programs are also available for professional Ultra4 teams needing guaranteed performance at all times.

More output at idle for powerfull charging at all times

The Legal bit......

The 2 year performance gaurantee covers defects in materials and workmanship including replacement parts and labor to repair the unit for a period of TWO YEARS from the date of purchase.

Expenses for repairs performed by the customer or another party without the express written permission of RED Winches will not be re-imbursed or warrantied by RED Winches.

Expenses incurred for installation or removal of the alternator or accessories are not covered by the warranty.

The 2 year performance guarantee will be VOID if the unit is physically abused, misused, improperly installed, not serviced properly or is not used in the original application it was built for.

This warranty is NON-TRANSFERRABLE. A copy of your original invoice and initial product registration is required to receive warranty service.

The customer is responsible for any and all shipping costs for the alternator to and from the RED WInch facility 

Delivery varies between 2 days and 3 weeks
