I hava a raymond with codes - 2b - 6q - f4 - They are sparatic and its usually fine then it will stop. The operator also said that it lost its plugging ability but i have not been able to confirm it. It works fine for me. The unit was really dusty and i blew it out. The ignition switch had a couple loose wires and smelled burnt so I replaced wire connectors and cleaned out switch and tested it. Its tests ok but I still think its the problem or part of the problem. Can someone tell me what the codes are?

Thanks!
