This NAPA unit also went out right after I got on it!
What causes the internals to move towards the housing and to cause this?

I have attached a picture showing what happened to my last NAPA unit and I am assuming that this one has done the same thing.

I am looking at this Milodon #16250 from Summit. Does this look like the HD/Police unit?

Thanks everyone!
