New electro couplers work on test track, not on layout. What gives?

Well, I replaced the electro couplers on my GP35, (6-38791) with new Lionel parts. They work perfectly on my test track. Front and rear open instantly. I power it with a PW ZW. However, they do not fire on my layout. I hear the 'buzz' most times when I send the signal from the Cab2. The layout is powered by a ZWL. Voltage on both tracks is 17.4. I'm stumped. On the bright side, while replacing the couplers I also replaced the fan motor and batting and it now smokes like a banshee! By the way, I've never had this problem with my MTH electro couplers...
