This problem has me going crazy ,i have four independent loops ,when i power up track 1 ,track 4 powers up at the same time ,i can't figure out why this is happening anyone have any ideas why this is happening ? I haven't changed any wiring at all .I just had another problem that whenever i put a conventional engine on track 1,i couldn't control the power to the track ,as soon as power was applied it would take off at full speed ,i then took the conventional engine & tried it on the other 3 loops & it worked perfect ,so i thought that possibly the power master was bad ,so i had a spear one so i tried it ,same problem then i thought maybe it was the cab 1 ,i have a spare one & i still had the same problem ,then for some reason i checked on the side of the power master & the switch was set to command mode ,stupid me when i was wiping the dust off of the power masters & power house 's i accidentally moved the switch to command mode ,getting back to why i am powering up two tracks at the same time ,i have no idea what to do .
OK , i'm sorry i figured out why i was powering up two loops at the same time believe it or not i made the same stupid thing as i did with the power master ,when i was dusting i accidentally moved the switch on the side of the power master for loop 4 to program & when i was changing power masters for loop 1 they both were programed for loop 1 ,lesson learned : NEVER CLEAN ANYTHING ON YOUR LAYOUT ,let stay dirty that way you won't screw abything up !!!!!!!!!!!!!!!!!!!!!!!!!
