Welcome to BGW!
It would be best too start a new thread, instead of hijacking an old one, but what charger do you have and which fuse is blowing?

thank JohnnieB, i was looking for the charger manual!

i would guess it is because components capable of both polaritys are cheaper to use on the lower current field circuit, instead of getting both polaritys on the high amp armature circuit.

Unless I'm mistaken, doesn't the same current flow through both the armature and field (stator) windings in a series motor?
