Brise Motorsport Alternators are lightweight, high efficiency units, ideal for demanding competition applications. Compact design gives the highest output power to weight ratio.
All Brise Alternators are 100% new manufacture (not rebuilds) and are fitted with twin internal fans, internal heavy duty regulator and high speed bearings. The uprated versions of each type feature many internal modifications capable of increasing the maximum output to double that of the standard unit, although be aware that the maximum output is available only at higher speeds / RPM.
Two types of the internal voltage regulator are offered, the standard (3 wire) item has a warning light connector and also requires a 12V supply wire (ignition switched). The third wire is for the main battery cable, connected to a 6mm stud for security and low resistance.
The one wire regulator features higher voltage output (14.9V) and only requires the battery cable connection. This type does not have a warning light facility.
Alternator fitting kits are available for many engine types:
Mini,
Ford Pinto,
Ford Zetec,
Ford Duratec,
Caterham (K series)
Direct bolt for bolt replacements are also available for many models, in standard or uprated form.
Uprating of Rally car Gp N. alternators for double standard output, without changing external appearance, (donor unit may be required)


Brise Competition Alternators are 100% new units and offer the benefits of small dimensions, light weight and high reliability. All feature low drag, high speed bearings and a special voltage regulator is available allowing single wire connection. They are available in standard or uprated form, high output units are denoted by suffix‘S’ on part number. All alternators are supplied with steel pulleys.
