my 10ee exciter arrived with a non working exciter
I am trying to get it working. It seems like it was not wired according to the schematic and the replacement brushes were never seated.
I have a few questions.
1. there is a variable resistor in series with the shunt field. where should the resistor physically be located?
mine was bolted to the outside of the exciter casing with the wires running through the opening.
it didn't look like that was the factory mounting location
should it be mounted inside the exciter?
More importantly to how many ohms should the resistor be set?
i think mine goes from zero to 200 ohms.
2.it looks like there where replacement brushes that were never seated
the replacement brushes did not have a wire connected to the back. it looks like the wire had been removed
and they were relying on the spring for connectivity
should i rely on the spring or solder a wire on there?
3. it looks like both the series field and the shunt field are wound around the same core
so on both sides on the exciter there is a winding. each winding has two wires coming out of each side.
there is a heavier gauge wire and a lighter gauge wire.
i am trying to figure which wire goes to which field
i assume that the heavier wire is the series field and the lighter wire is the shunt field
can anyone confirm which wire is for which field?
Thanks in advance

here you can see how my resistor is mounted
