1.  HO scale 4-6-0 2.  Powering frogs does not fix the actual problem.  When the locomotive crosses a frog, it only ever has 1 set  of drive wheels (out of 3) contacting a non-powered section of track.  Additionally there are power pickups on the tender.  Secondly why spend a lot of money and time powering every single Insulfrog turnout on my layout, when every other locomotive runs across them without any problems (including the Bachmann 44 tonner and 4-4-0)? Using the continuity setting on my multimeter, I have determined that the rear tender truck power pickup wiper (say that 10 times quickly) does not make good contact with the wheels at all times.  Addtionally it is loose under the screw.  New problem.  I attempted to remove the screw and it just spins in its hole without coming out.  Is there a nut on the back that is not locked in place?  Edit: yes there is! Bachmann, why do you hate your customers? Also the center drive wheel on the engineer's (right) side of the locomotive has intermittant continuity.  Why? I cant figure out, unless the wiper is stuck to the side of the frame with grease from the factory.  This aggrivates the above problem with the rear tender truck.  Note: Continuity was checked from wheels to the red/black 2 wire plug between locomotive and tender.  This, I assume, is the power collecting circuit for the decoder.  The exploded parts diagram was not clear on this.
