Before I call Lionel, i thought I would seek the forum for advice.
I purchase a Lionel zw-l during Charlie's May sale. I hooked it up to my tiu with each throttle powering one of the tiu four power inputs. Each tiu inputs then powers a loop, with a total of four loops being powered. It worked great, until two night ago when the the "d" throttle stopped working. I powered it down and check the cars on the track to make sure there was no short. I powered it up and it didn't work (I used a test light to verify). Then I removed everything from the track and tried powering up again, no power. The other 3 throttles work fine. I let it rest for the night. the next day I tried it again. The light on the gauges for throttle d lite up until I applied power. At this point I disconnected the wires from the terminals of throttle d and tried powering it up with no results. I used my test light on the terminals and no power.
I did check the breaker and they weren't blown. Any thoughts?
Thanks Jim
