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.

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.

The battery showed 12.7VBased on your suggestion it would seem I have a cable or connector failure between the rectifier and the battery. If it is a direct connection between the two I can run some temporary cables to bypass the existing cables and connectors. Can you confirm if this is the case?
I did have the red and black disconnected to the regulator with the engine running. That was how I got the 1.8V.QuoteI am sure this is as frustrating for you as it is for us, but... Final test... Engine off, with the regulator connected to the battery, can you measure the voltage at the battery, and the voltage on the red and black of the regulator (do not unplug it!). If these two voltages are not the same, then the regulator is not correctly connect to the battery, you can do a continuity test to see which cable broken. It is a direct connection and you can run temporary cables, but this might not fix your problem.

ITS FIXED!!!!!I spent a couple of hours last night taking all the joints apart and cleaning them up. I also stripped the Power Pole connectors to make sure they were making good connections. The fault was with the black cable from the rectifier and its connection in the Power Pole. The cables are almost as large as the housing they solder into when connecting to the terminal in the Power Pole. There must have been a bad connection here even though it has performed very well for at least six months. I re-soldered the connector, put everything back together and hey presto I now have 14V at the battery with the engine running.Thank you to everybody who contributed for your help and patience. Its very much appreciated.
