Quoting Removed, click Modern View to seeIt is not likely a matter of "exciting". Your generator/regulator system is disconnected from the battery until the regulator senses a pre-set voltage coming from the generator Armature terminal (6.1 to 6.5 volts) & at that point, the reg connects the generator ARM to the battery (BAT). If the reg is not operating properly, this may be connecting only after your speed is up higher than normal (thus a higher than normal connection voltage) OR the generator may have problems & not producing 6.1 to 6.5v until speed is above normal. The latter can also be a result of regulator problems in the Field control contacts......i.e., if field contacts are not making good electrical contact, the generator field current suffers & you have low gen output & need higher speed to reach the 6.1 to 6.5 volts. Check the " failure to connect" BAT to ARM by jumpering BAT to ARM, while at a normal speed & no charging, & see if it begins charging. If not jumper the Field terminal to a good solid ground & see if it starts charging. If either "fixes" your problem, then get a new regulator. If not, come back, as there are other things to do in checking the generator.
