For 3-Phase Field-Excited Systems only. This includes BMW Airheads, and Moto Guzzi's with Bosch alternators, 1970's Honda 4 cylinders, Yamaha XS650's, Kawasaki KZ's and Suzuki GS's etc.

The Field-Excited 3-Phase Reg/Rec from Rick's Motorsports Electrics is the best UNIVERSAL solution we've found for upgrading your OEM field excited charging system.

A versatile and rugged combination regulator-rectifier compatible with both type-A and type-B field-excited systems. Technically this is a type-B regulator, but it works perfectly with type-A systems. Despite being engineered for optimized functionality with Lithium Iron Phosphate (LiFePO4) batteries, it is 100%, fully compatible with traditional lead acid chemistries (including AGM and Gel Cells). This reg/rec is our go-to solution for all our BMW Airhead, and vintage Moto Guzzi builds.

Add the Apex 2.8 High Amp Connector Kit  from the dropdown menu to include the best Reg/Rec connector on the market!

Highlights:

  • 14.2 Volt set point (gets the batteries topped up without overcharging Lithium cells)
  • Waterproof
  • Compatible with all 12V 3-phase field-excited charging systems
  • Rated to 400 watts or 30 amps
  • Very low heat generation

APEX 2.8 Connectors are a heavy-duty sealed connector ideal for Stator to Regulator connections but versatile enough for many other motorcycle applications. Large terminals means large contact surfaces allowing each to carry up to 40amps of current while the design makes these the most compact 2.8mm system available. Designed to survived harsh automotive conditions under the hood and can be found in many Mopar cars and trucks.

Highlights:

  • Ideal for Regulator/Rectifier connections but versatile enough for many other applications.

  • 40 amps per terminal

  • 2, 3, 4, & 6 pole options.
  • Two terminal sizes 14-16AWG and 16-20AWG*

  • Easy to assemble and service

  • Easy release latch with locking mechanism

  • Mounting tab

  • Meets or Exceeds USCAR and GMW3191 Standards 

  • Watertight up to IP 68

  • Temperature range -40ºc to 150ºC 
  • Vibration Performance 12 G

**On an 8 wire Stator we use a 2 pole for the Field Excitement wires and a 6 Pole for the remaining wires.

    Bought this to replace the old 1975 system on my CB550 and also help the lithium ion battery I have on my bike.
