Got gremlins with your A1, with the circuit board style power panel? Intermittent electrical issues? My truck had relay sockets practically falling out. Its hard to tell unless you look carefully from underneath. There are traces on both sides of the board so it should be soldered on top and bottom. You cant see the top solder joints in most spots its covered by sockets. No wonder these trucks get a bad rep from the mechs this would be a hard problem to troubleshoot. It is repairable with a good soldering station and some quality thin 60/40 rosin core solder. You can carefully resolder the bad areas the solder should get drawn thru the back side to the top traces.
