Terry, a fully charged 6 volt battery consists of 3 cells of 2.1 volts each meaning it should measure about 6.3 volts sitting and if coupled up to a good charging system I actually see 7 volts as fine BUTTTTTTTT if it stays at 7 "all the time" I guess it could possibly (depends on battery n charging system) outgas some??? But I doubt it and doubt that you have any worry AND SURE NOT in any short period of 7 volts would it be harmed. The charging system has to be over 6.3 volts before the cutout engages and ever charge the battery anyway, and 6.5 to 7 is typical of voltages. Thats why the lights can glow noticeably brighter at wide open throttle versus at idle!!!! Cus the voltage is increased

You asked about adjustments,,,,,,,,,,,,,it depends................

Does it have a full fledged 3 wire Voltage Regulator (can be adjusted) or a 2 wire Cutout Relay and uses the Hi LO light switch field current charge rate control????????? If its the light switch controller and theres no lights on, I would set her to Low Charge if youre worried about overcharging.

The only way to tell more about the battery is to test its specific gravity, but generally speaking, I wouldnt be too afrad if she read 7 volts and would go ahead and let it charge at that for a good while before switching to Low charge if you have a light switch control.

You may wanna take a look at the batery to insure theres electrolyte above all the plates and no cells exhibit a gray or milky color and have a battery shop load test it if youre worried, but is she stays charged n she cranks over well youre likely fine and no need to worry about 7 volts UNLESS she stayed there like all the time. Also, if she keeps needing water added, thats a sign of overcharging (outgassing n boil over) THEN you need to have things checked out or at least manually use the Low charge position more often. Back when I had Farmalls I left them in Hi charge a good while and if no lights on after a while I might switch to Low, but never had any overcharge problems I recall if I didnt switch. Those Generators werent the strongest ever made ya know.

Good Luck n God Bless
