Are the red marker lights on the trailing A unit powered by the slave board or from the lead A unit board. Lead green marker lights wqork fine, but the red LED's on the trailing A unit occasionally blink but then go off quickly. Any thoughts on how to remedy?

Most likely spring contacts when shell is attached. Remove shell and stretch springs. G
A shim or two under the spring bracket works, also. Those springs are sometimes the "****" variety.
Do we know where the marker lights get their power? From the slave board? Or, from the main board in the lead A unit? The spring contacts seem to be working fine. This may not be the problem. Any other ideas?
