Sam..... ..look at the back end of yer 1-terminal 9N genny. Theres a "manual charge adjust" called the 3rd brush. It can be adjusted to as high a 17 volts open circuit (no battery load). The 2-terminal roundcan cut-out relay under yer battery tray has NOTHING to do with the output of the genny but just disconnects the battery when the engine stops so the gutts of the genny don't discharge overnite. CAUTION: TOO HIGH charge volts will melt the gutts of your 1-terminal squarecan ignition coil. Check yer coil volts with yer new 8 volt battery, ennything OVER 3.5 volts and yer gonna have sparkie problems. Guarantee it!!! The 8N's 3-wire squarecan voltage regulator CANNOT be shadetree mechanic adjusted to adquately charge an 8 volt battery. I am NOT A FAN OF 8 VOLTS on N-Tractors and just because BillyJoeBob down at the corner whittlin'n'spittn club sez its the thang to do 'cuz he does it on his ol' JD or Farmerall or whatever doesn't automatically mean it works for N-Fords. 8 volts is a worser bandaide for tired engines than a 12 volt conversion. Remember the 6 volt mantra: "keep'em clean, bright, and tight". And don't be fer usin' enny of them tharr wimpy ferrin made 12 volt battery cables. Gittcha some 'arrychestd 'merrcum made one-naught (1/0) thick as yer thumb battery cables for eazier 6 volt starting..... ....respectfully, Dell, a 12 volt advocate for the right reasons That said, I haven't found the right reason to convert my eazy starting 6 volt '52 8N and I know how to do it right the 1st time. Infact, I know 7 ways to do it and they all work.
