Weekendrider and 5Twins are right, mine is the same as the one posted by WER, flip the thing over and lets have a look at the other side...(please post picture up).
looks like you have quiet a "Frankenbuild" going on there, you cannot just put in a regulator that "looks the same" into the charging system. From what you posted I was thinking that the regulator was from another year, so I spent my time looking at the diagrams and found that they are the brown, green, black wires throughout the diagrams until they changed in the later years....
Do you understand how the regulator and rectifier work at all? Again have a good look at the wiring diagram, it's the key to getting your charging system working.....with the right components
