I suggest your assumption be correct. As to the dome light specific applation, many of them had on-off switches mounted at their location. When turned off and on the connecting wire acted as a transmitting antenna for the tiny spark created during its operation thus recieved at the AM radio with a loud POP. The Motorola filter was nothing but a capacator to damp that spark and reduce the noise in the radio. A cool device Very well made encased in copper and embossed with the MOTOTOLA name as well. Input and output leads were marked bat and load so you get the pop grounded before it hit the supply wire. Just my ancient opinon. Don

Anybody know what I am talking about?

I have acquired an old Bijur motor lighting system generator. I would like to know what voltage and polarity it operates. It is labled Packard System Ser. N213 M973 and also N34 TR97E on the cutout relay. Patent dates from 1914 thru 1916. It was part of a sale on old one cylinder hit-miss engines. It is mounted on a board and a flat belt pully attached where the gear or sprocket should have gone. It motors up when connected and the cutout realy manually otperated. I would like to use it for display with one of my hit-miss engines. Is it worth anything to speak of for the Packard collectors? I found a picture online of a 1918 "twin six" car showing the exact generator.
