Haven't got any diagrams.

Check the AC/DC rectifier behind the dash panel (the finned thing).

To do this check whether the two wires from the dynamo will light a test light (battery disconnected, engine running). I think you'll find two bullet connectors somewhere below the exhaust manifold, make sure they're contacting.

If there's power up to the rectifier check the remaining wires on the rectifier (3 I think) to see whether any combination will light the test light (as above).

If there's power into the rectifier, but not out, it must be a faulty rectifier.

Good luck

Here's a scan of my B7100 electrical diagram. It may be the same as your 5100.

:D just got time to look at the b5100 again today and after following wires found a wire off the iginition switch.After connecting it everything seems to work and it is charging at 14,5 volts at 50% revs.thanks to those who replied and the wiring is the same as the b7100.
