I just tested the regulated output on mine, having blamed my cheap battery last night. With main beam on at tickover I have 13.94V and this drops to 13.29V at 5K rpm. Is this the same regulator fault?

Morning all.

Good show Stooster, a pleasure to assist. It sounds like it's sorted, 14 volts average will do the job just fine, without the danger of overcharging.

Chazzyb Your regulator may be developing a fault, although it's not unusual to have the voltage drop a little as the RPM rises. Keep tabs on it, & if you get any sign of a flat battery (providing it's a good battery). You had better check the alternator & or change the RR.

Cheers.
