[quote user="trainnut1250"]By cutting the frog jumpers it allows the closure rails and points to be jumpered to their respective stock rails. They are now always hot and always the correct polarity. No more reliance on the metal tabs or direct point rail contact to power the points and frog. This makes the turnout more reliable electrically. The beauty of the current Peco design is that the stock rail to closure rail jumpers are easy – there is a spot with no ties that you can solder them in underneath the turnout, the frog is already gapped and they have soldered a wire to the frog for you – very nice. [/quote] This is my model railroad club's standard practice with electrofrog turnouts.  Never rely on the points to provide electrical continuity.  We power our frogs from Tortoise machines.  Note: If you do use tortoise machines you may find that you have a momemtary short when the turnout is thrown.  This is remedied by removing the spring that holds the turnout against the stock rails, as it is no longer required (Tortoise machine does the spring part for you).  This spring is located in one of the ties near the tips of the points removable by bending 2 metal tabs (new style turnout), or on top of them under a centered plastic detail piece that is removable by bending 2 metal tabs (older style).  You can also use the Caboose industries ground throw with the electrical contacts (119R and 220S)
