I have an IC FE 300 with air brakes . Before I tear the bus apart thought I would get some ideas what is wrong . We have an 8 light system . When the ambers are activated either the door or the stop paddle cancel the ambers and the stop paddle comes out . Well the stop paddle will cancel the ambers but the door won't cancel .So I thought switch on air door cylinder was bad . replaced that didn't work . The wire going to the weldon flasher from the door shows no ground power from the door . So I am wodering if there is someplace els to look . I can ground the terminal on the welo for the door and it cancel amber and puts out stop paddle . My concern is we had nw camera systems installed by another company and they may have cut the wire from the door to the weldon .So before I run a new wire or figure out what happened . Am I over looking some other test . Thanks
Found my problem the wires on the door switch came unattached . Thought the switch above the door controlled this function of actvating the stop paddle after the ambers
