Civilian Bosch mechanical voltage regulator

  1. The gray/red (or red/white) wire is connected to the bottom right connection (bottom as in closest to the ground, right as when seated properly astride the motorcycle). Some Bosch mechanical voltage regulators use a 9.5 mm female spade terminal; others use a 5 mm ring terminal.
  2. The white wire with the 6.3 mm female spade terminal is plugged onto the top right connection (top as in furthest from the ground, right as when seated properly astride the motorcycle).
  3. The red wire with the 9.5 mm female spade terminal is plugged onto the top left lug (top as in furthest from the ground, left as when seated properly astride the motorcycle).
