Norton Condenser (54420128)
An ignition condenser (capacitor) for the contact breaker circuit, part number 99-1043.
This is a condenser, also called an ignition capacitor, part number 99-1043. It shows up in the catalog under the ignition capacitor grouping alongside T100C headlamp listings and in the basic electrical equipment section, so it lives in the ignition circuit rather than anywhere mechanical.

A condenser works alongside the contact breaker points to stop arcing when the points open and close, which keeps the ignition timing consistent and the points themselves from burning out prematurely. It's a small, sealed component, usually tucked in near the points or under the side cover depending on the ignition setup on your bike.
Our catalog record on this one is brief and spans appearances from 1969 through 1975, but it doesn't pin down a specific model. If you're chasing down an ignition miss or your points are pitting fast, this is a common culprit to check, but call the shop and we'll confirm fitment before you order.
