Transit-We ran the generator last January for 5 days straight (off at night), and as I recall the readings were 124/125 volts per each leg and 240 volts combined.
hr3-If memory serves me right, the no load voltage was around 127/128 in January. The generator (alternator) is brand named Niagara, with Generac in small letters on the bottom of the name tag. Model # 5403-3, serial #0161083.
Many thanks for the responses. I only moved the gears what would amount to two teeth from one power head to the other. Would that small adjustment caused the increase in voltage? Should the voltage regulators maintain a setting of 115 volts per power head as listed on the data tag? Should the regulators be checked?
I think I am going to look into brush end bearings with a larger diameter and have the end bell bored out for proper fit. Just have to get the old bearing off. No puller space, so modifying a auto alternator pulley puller and hope it will have the strength.
