2003 Georgetown by Forest River. The motor home won't start. I've jumpers the starter relay to crank the engine but the engine will not start and run. The 20 amp breaker for the PCM/TCM-BAT was blown and there appears to be a short in the circuit as a new fuse blows immediately. I'm trying to locate the PCM and TCM modules to disconnect them and see if one of the modules is the problem or if it is the wiring. Does anyone know where these may be located? I'd appreciate any help. Thanks, Dan
