Mike, Im NOT a fan of the 8 volt system, its a band aid approach to cure a problem. If one insisted on converting to gain starting performance especially in cold weather, may as well go ahed n convert to the more standard 12 volt n be done with it.........

It wont harm a generator in the short run, it may run just a tad warmer n draw a few more field amps. However, whether or not the Voltage Regulator requires adjusting depends on what kind of system you have. If its a 2 coil VR with a cutout relay and a current only control relay, she could still charge an 8 volt battery. However, if the VR has a Voltage Control Relay it may need adjusted to better charge an 8 volt battery. If it were the simple 2 wire cutout relay ONLY it should charge with no adjustments.

NOTE an 8 volt battery will cause the 6 volt coil to draw a tad more amps n it can run just a bit hotter plus the points will burn up a lil sooner unless you add some ignition ballast. Likewise, 6 volt lights will burn real bright but burn up sooner.

In 6 volt systems you can gain starting RPM and performance by using the biggest heaviest highest CCA rated battery that will physically fit in the comparment PLUS use 00 gauge Battery n Starter n Ground cables.
