Ignition capacitor (type 2MC) (99-0737)

Lucas type 2MC ignition capacitor for the electrical box circuit, now superseded by 99-0737.

PN · 54170009
Superseded by 99-0737.

This is the Lucas type 2MC ignition capacitor, an electrical box component that sits in the charging circuit on machines running these figure groupings, including the T100C and TR6C in the electrical box and headlamp shell wiring. It shows up in catalogs from 1968 through 1973 and has since been superseded by 99-0737, so if you're chasing this old number down for a parts order, that's the current reference to ask for at the counter.

The capacitor's job in this circuit is to act as a buffer for the ignition and lighting system, smoothing out voltage and giving the system something to draw on if the battery drops out. It's a small component but an important one to have functioning correctly if you're running the stock charging setup.

We list it here under the old number for anyone matching against a vintage parts book, but when you order, know you'll be getting the 99-0737 part since that's what this one turned into.
