Polarizing a generator

[Conaway2]

I’ve read a lot of posts on this, but the procedure still isn’t completely clear to me.

I’ve just disassembled a generator to re-wrap the field coils with Scotch glass electrical tape, and then cleaned and re-assembled it.

It will motor with my 6 volt 10 amp battery charger attached to it - negative to output post and positive to generator case.

If I connect a multimeter to the unit while spinning it in normal rotation direction, Ican measure 70 mV on it - no cutout attached.

Questions -

is a battery charger enough to polarize the generator ?

If the generator is working, should I see more than 70 mV at the output ?

Thanks - Jim
