I purchased a set 100 a few months ago and just started to hook it up yesterday to my layout. I am having a problem getting it to work. I am using the Set 100 with 2 gold Lenz decoders. My problem is: I can not get an AC voltage greater than 8.0 volts on the main track. I have isolated the track to a 3 foot length to try and get it working but to no avail. When I try to query a decoder I consistently get an error 02. I’ve tried the programming track and was able to query the loco address and move the train about 1/10of an inch. I have tried 3 different decoders but it seems to me unless I can get a higher AC voltage I am out of luck I have tried resetting the unit to factory but I may be doing it wrong. I checked the output of the power supply and it is 15 VAC going into the control box. I am new to DCC and I would appreciate any help!
