Default Re: 3 brush generator ????

with the 3 brush the amps are set by the 3rd brush, the voltage is set by the battery and it's willingness to accept charge, if the battery is low on charge the charging voltage will be lower
what is the voltage on each side of the cutout, a diode cutout will have a .5 volt drop on the "B"side ----if you put in a 8 volt battery the generator will just make more voltage

if you have a fun projects regulator jumping it can fry it, if it is original relay type it can be jumped, diode type can be jumped too

if the field ground wire is disconnected the generator should stop charging

if the battery is disconnected from the generator it can easily make over 40 volts---till it has meltdown
