I got my alternator hooked up yesterday and noticed that my meter showed a little over 14 volts and it was still charging at 5 amps. I looked at the information I have on the alternator and regulator and it shows that voltage should be between 14.2 and 14.8 volts at 1,800 RPM. That seems excessive to me. I was expecting from 13.5 to 13.8. I am going to put my digital meter on it and get some better readings later today.
The higher voltage might be O.K. on the engine starting battery of an Onan generator (the original application for the Synchro alternator), but I think it is too high for my motorcycle battery and all my electronics. Anyone care to comment on their experience and voltage levels with this alternator.
