Hold the speaker in place and run a bead of RTV around the
speaker and on the tender floor to hold it down, making sure
it is sealed tightly to the floor. This is a good time to reinstall
the tender weight – you want the tender to weigh at least 5
or 6 ounces when finished. Set it aside to cure overnight.
Decoder in the tender
There are a couple of extra challenges encountered when
mounting the decoder in the tender:
(A)
you will need to find a place for the decoder in addition to
the speaker,
(B)
you need to run power from the right rail to the decoder.
Delivering right-rail power can be done in at least three ways:
(1)
You can make pickups on the tender trucks for it
(2)
you can use a wire in the cable from the engine to the
decoder and
(3)
you can reverse the draw bar – soldering the stud to the
engine and drilling the tender for the insulated draw bar
mount.
