Reply to "Postwar 2356 F3 - Can't Eliminate Excessive Collector Sparking"

Here are a couple of thoughts. You replaced the rollers, what material are they made of? I have found the older sinter iron spark more that ones turned and machined. Also you could solder a flexible wire jumper from the bottom of the pick-up arms to the solder lug on the plate casting on the underside. This would also help greatly. And if you already haven't, polish the roller pin with some fine sandpaper. And anytime you get a locomotive or car where the roller rides on it's own axle, add a very small drop of oil to the ends. But not on the ones that the roller rides on a stationary axle.
