Powerhouse generator brush reconnection

[Mabel1930]

Hi all,
I’ve got an Erie lead that’s become disconnected from the adjustable brush in my powerhouse generator. I’m curious if I need to replace the whole brush and lead (and if so, where to best source that as I don’t seem to be having luck on the supplier sites), or if it something I could resolver myself to the housing piece or brush itself. Any advice would be appreciated!
