Managed to get some checks done on the bike at the weekend.

The ac generator has been rewound but I checked anyway, 0.8 ohms on all yellow wires and around 80v at 5000rpm, don't know if the volts are OK as I couldn't find it in the manual. Only thing I noticed is when you pull the connector apart the revs rise but that might be normal I don't know.

Battery was tested on a proper load tester and is fine

The pulse generators are OK reading 214 ohms and and 219 the latter being very close to the top spec of 220 ohms. I have a new set which I tested and are 200 and 203 ohms which is right in the middle of specs so I will fit them I think. The pulse generator is mentioned in the battery undercharged part of the manual.
