If it now has a 12 volt battery but its still the old 6 volt coil, you can add an external series voltage dropping (12 to 6) series ballast resistor (typical values in the 1.2 to 2 ohms)after the ign switch before and ahead of the coil so it drops 6 volts leaving 6 on the coil as a 6 volt coil was designed for, orrrrrrr toss the coil and use a 12 volt rated coil that requires no ballast....... "12 volts not for use with ballast" or "12 volts no ballast required" or simply "12 volts" are typical labels on that coil
The Voltage Regulator (if it used one instead of a cutout relay) and genny are for a 6 volt system so you cant simply add a resistor to fix all that. You can get a 12 volt genny and a 12 volt VR or convert to a 12 volt alternator.
If you change from Pos to Neg ground (like most alternators require) the ammeter leads need swapped or else it will read bass ackwards.
Also if its a coil ignition (NOT a Mag) and you change battery polarity the coil leads also need swapped. Dont let anyone tell you ignition coil polarity dont matter and you can wire it either way, its true you can still get a spark if its wired at the wrong polarity, but the system works best and is more efficient if the coil polarity is corect..

Today's Featured Article - Harvestin Corn in Southern Wisconsin: The Early Years - by Pat Browning. In this area of Wisconsin, most crops are raised to support livestock production or dairy herds in various forms. Corn products were harvested for grain, and for ensilage (we always just called it 'silage'). Silo Filling Time On dairy farms back in the 30's and into the first half of the 40's, making of corn silage was done with horses pulling a corn binder producing tied bundles of fresh, sweet-smelling corn plants, nice green leaves with ear; the
