Well lads.

I’ve an issue with the charging system on the gsx 1400.

Bike would struggle to start and most of the time would need to use the booster pack on it.battery was only a year old .

So I recharged the battery ,read 12.7v so all good.

Voltage at idle eventually got to 13v but when I increased the rpm the voltage dropped.

So I tested the rectifier and all diodes tested fine.

Tested the stator winding resistance and all in spec of the Haynes manual.

But when I tested the AC of each winding from the stator at 5krpm , I was only getting 45volts instead of a stated 60v needed in the manual.

Does this explain the crappy charging system and why the volts decrease with increased rpm?

Is there somewhere to rewind these? Preferably in a day or 2?
