DYNO BRUSH PLATE NOS
A Lucas dynamo brush plate, part number 200738, that holds the carbon brushes against the commutator.
This is a brush plate for a Lucas dynamo, part number 200738. It's the component inside the generator end that holds the carbon brushes against the commutator so current gets picked up as the armature spins. Without a sound brush plate the dynamo won't charge properly, and worn or cracked plates are a common reason for a no-charge complaint that isn't the armature or field coil.

Our records tag this one to the E3L and E3LM Lucas dynamo models, but we don't have a lot of appearance history on it in our own catalog. If you're chasing a charging fault or rebuilding a dynamo, check the plate for cracking, scoring on the brush tracks, and make sure the brush springs still have tension before you put it back together.
Give us a call if you want us to confirm this matches the dynamo you've got apart on the bench before you order.
