Frank Cerutti Posted January 8, 2020 Share Posted January 8, 2020 I am investigating the operation of the ignition switch fitted to the Maxwell late model AB or the AC. This switch has 3 positions, MAG, OFF and BAT and 4 wires, at terminals AM, 2, B-C and B. I have attached a photo of a switch with the cover removed. This switch has been modified. In operation, when BAT is selected the main contact arm goes between terminals 2 and B. When MAG is selected the main contact arm goes between terminals AM and B-C and a temporary connection to 2. Does anyone have a photo of an AB or AC switch which shows this temporary connection. Any response is appreciated.

Layden B Posted January 9, 2020 Share Posted January 9, 2020 Since most coilboxes of the era were supplied on various cars, can you yell us what make and model of box this is? Link to comment Share on other sites More sharing options...

Frank Cerutti Posted January 9, 2020 Author Share Posted January 9, 2020 Layden I’m now thinking that may not be the answer you wanted. The switch/coil box is Splitdorf, model unknown, marking “1912” stamped into the outside of the back wall of the box. Frank Link to comment Share on other sites More sharing options...
Layden B Posted January 10, 2020 Share Posted January 10, 2020 This is closest that I have come to with that bar for the switching element. Don't the 1912 Messengers have Delco equipment? Link to comment Share on other sites More sharing options...
Frank Cerutti Posted January 10, 2020 Author Share Posted January 10, 2020 Hi Layden. Thanks for your reply. The car in question is a Maxwell model AC Messenger, 1912, with the Flanders body. It is fitted with a Splitdorf model H low tension magneto and a Splitdorf coil/switch box. This Splitdorf coil/switch box has a 3 position switch and 4 wires connected to the switch. This ignition system is identical to that fitted to later series Maxwell model AB. The earlier model AB too is fitted with the Splitdorf model H low tension magneto but the Splitdorf coil/switch box has 3 position switch and 6 wires connected to the switch. I have documentation on these 3 examples. Frank Cerutti Maxwell LD9024, 1909 Townsville, Australia Link to comment Share on other sites More sharing options...
cudaman Posted July 14, 2022 Share Posted July 14, 2022 Frank, I realize this thread is old, did you ever get your answer? That switch looks very much like the switch on the coil box of my 1912 Flanders, here are some pics. Link to comment Share on other sites More sharing options...
Frank Cerutti Posted July 14, 2022 Author Share Posted July 14, 2022 Thanks Cudaman The question was posed while I was working on my contribution to David McCredie's Maxwell book. I appreciate your follow through. Frank Cerutti Maxwell LD9024, 1909 Townsville, Australia Link to comment Share on other sites More sharing options...
