I seem to be losing the connection between my steamer and its tender.  It's an MTH PS3 M1 steam loco.  The steamer runs fine, then stops and shuts down unexpectedly.  As soon as I add pressure to the connector at the tender, it immediately starts right up.  The connection doesn't seem to be coming apart by much, but maybe that's a reflection of my poor eyesight.  I don't feel a click when I try to reseat it.  I've also cleaned the connection with electrical contact cleaner.  Does this happen often with these connections, and is there an easy fix.

Al,

I don't feel a click when I try to reseat it. 

It sounds like you aren't firmly seating the connection at the tender. You need to press firmly until it cannot be seated any further. As long as you line up the connection properly (and it's kind of hard not to line it up correctly), you can exert a fair amount of force without doing any damage.

It's also possible, though less likely, that the press connection at the engine side is not firmly seated. You should be able to see if it's tight by visual inspection.

Inspect the connector on the drawbar that plugs into the tender.  No bent pins, no folded over plastic on the connector that might prevent it from seating fully.

If that is ok, put both on the side on a table and press drawbar into the tender connector firmly.  Visually see that it is seated.  When done right it takes good pressure to remove it.  Once you see it fully seated and feel the necessary pressure you will be more capable to seat it when on the track, but many just do it on the side and then move it to the track.
