I purchased a used three car Vision Line reefer set months ago and just now got my Legacy 990 system to actually operate the features of the cars. Everything seemed to be working great. Then I noticed smoke coming out of the car with the electro-couplers. At first I thought, wow I guess I have a load of dry ice -- until I smelled it.
The electro-coupler worked/works. I removed it from the track and slightly burned my finger on the coupler, it was that hot. I let it cool while I googled the problem -- not finding any results on a brief search. I put it back on the track and it did not get hot until I operated the coupler. The coupler would not latch which told me it was "stuck" with power to the magnet to release it.
Since this is electronically controlled (I thought) momentary switch, I'm puzzled. Is there a physical momentary switch in there that is controlled electronically?
Since this is the first thing I've ever done with Legacy, have I programmed it wrong somehow?
I exercised the coupler again after it cooled manually and then put it on the track and operated the car (not the coupler) with freight sounds at length. The coupler never got hot. At this point, I'm afraid to attempt it again since everything else is working.
Suggestions on what might be wrong with the electro-coupler?
