So I was suggesting measuring the battery volts with engine running while changing the system load. If the RR is working the voltage wont change and if not the voltage of the battery will drop as only it is supplying the demand.
The extra load could be from headlight main beam but better would be heated grips or some other 12v load connected across the battery.
voltage does drop slightly when I use the head lamps / break lights
