1983 R100RS Install Euro MotoElectrics 400 Watt Charging System

I’m upgrading the charging system from the stock Bosch 240 watt alternator to the Euro MotoElectrics (EME) 400 watt, Type III charging system. This alternator uses the same design as the Bosch one with an electromagnetic rotor with brushes.

I also decided to replace the stator cover, part# BOALT-StatFram107Plus and also replaced the battery (+) cable and the voltage regulator sub-harness. EME provides two cable kits: one has the battery (+) and (-) cables, part# BCK-475216 and the other has the voltage regulator and the charging system wires that connect to the diode board, part# BOALT-HAR80. The kit has some of the same wires included in the Type III charging system kit and is for the R80. But the voltage regulator sub-harness is the same as the one used on the R100 and the R80 kit is less expensive than the R100 kit as it has fewer wires.

I documented the procedure here.

I also made a video summarizing the procedure and posted it to my YouTube channel.
