i have a 3rd rail m1a w/ tmcc. on the side of the engine there is a switch for the smoke machine labeled. Conv/ off/tmcc. In the tmcc position the engine will not smoke. Not even a little. In fact I don't even hear the fan. with the switch in conventional. And while the rest of the engine is controlled by tmcc. it smokes great. Any suggestion with where I start to troubleshoot.
