1 MTH 40-1031 Arch Bridge (30" long)
1 MTH 40-1032 Girder brdge extension (12 3/8” long)
(My span required cutting off 1/4 of the extension.)
Bridge and Table Track Wiring Switches Table Track Power

North End of Bridge Table Wiring Contacts
South End of Bridge Table Wiring Contacts
Bridge Stands in Corner when Passage is Open
Circuit Board for Blinking Red Light
The 40-1103 Bridge Manual shows the "light control board" located in one of the three bridge piers. For the lift out bridge the "light control board" is placed in a box under the table. The mounting end of the "light control board" shown above was cut off to fit into the box. While installing the bridge wiring "switch contacts" I damaged the bottom two diodes and replaced them.
