<p>Look carefully at how your locomotive coupler mount works.  If it is metal with metal screw but platic coupler box with internal sleeve you are fine.  If you have metal to metal contact in a hot frame locomotive, be careful.  Some BLI steam and diesel locomotives have a hot frame (as indicated by a plastic insert above the coupler and verfied by multivolt meter), my BLI e7s and 4-6-2 have hot frames.  The 4-6-2 had a plastic coupler.  When I switched to Sergent Couplers I had to cut a piece of .010" styrene to insulate the coupler and use a plastic screw (I think thats how I did it).</p> <p>The the only way to tell if you have an issue is to take a multivolt meter and perform a coninutity check between coupler box screw and each wheel.  As long as you have an open circuit, no issues.  If you do you will need to figure out how to insulate (styrene, plastic screws, etc).</p>
