the jumperboard on the athearn rtr loco where the dcc chip goes it wont unplug. I tried everything with all my force i can use without breaking it to get it to unplug, but it wont! Can someone tell me if theres a trick to getting this off. I never have done it before so not sure. And the manual that came with the loco says nothing.
If you’re trying to remove the white 9-pin JST header plug, they do fit very tightly and require a lot of prying. Use a very small flat bladed jeweler’s screwdriver to pry from one end and then the other within the crack between the socket and plug, until you work it far enough out of the socket to pull it straight out.
