Maxwell AB or AC ignition switch

Recommended Posts

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.

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.
