Gen1 Generator

[PaulSmith]

The battery is not being charged. When I put a meter across the battery terminals I do not see any increase in voltage when the engine is revved.

I have a second Fazer and I transferred the rectifier onto that to check it was working. The battery on that Fazer increases to around 13.9V when the engine is revved and increased to 14.2V with the rectifier from the Fazer that is not charging. This has confirmed the rectifier is OK.

I measured the voltages of the white leads from the stator with the engine running. I used the connector under the side cover above the foot peg. They are around 22V at tick over and increase to 60V ish when the bike is revved. I did the same on the Fazer that is working and the results were the same.

I took readings of the three white wires going into the rectifier. They were reading the same voltage as I got at the plug under the side cover.

I then connected the three white wires from the stator to the rectifier and measured the red and black coming out of the rectifier and the reading was around 1.8V.

I have checked the fuses in the fuse box under the seat. I also found a 30amp fuse tucked down the side of the battery. That tested OK.

That is as far as I have got, I don't really know what to try next.

Please! Stop telling us half the storey. don't tell us what you didn't see, tell us what you DID see.

When I put a meter across the battery terminals I do not see any increase in voltage when the engine is revved.

What voltage DID you see before you revved and what voltage DID you say after you revved? 
Have you run the test I asked you to:

An additional test you can try: What is the voltage across the output of the rectifier with the bike running and what is the voltage at the battery terminals. Any significant difference would suggest a fault in the cable or connections between the two.

It is sounding to me more and more like a cable or connector failure between the rectifier and the battery.
