I thought this was pretty straightforward. I bought 2 new roller assemblies, and installed them on my 2046 tender trucks. Next I soldered new wires from the relay to each truck to the tab on the roller. On the track the rollers are shorting out. What have I done wrong?

Perhaps post a photo or two? I assume you insulated the roller assembly from the truck frame, including the screw.
How are the springs that hold the rollers down. I usually replace them since they weaken or corrode over time and loose their spring. Then the roller assembly slops around and shorts out.
This is one with a new spring. They are not strong to begin with.
What may be happening is when the pick-up assembly is installed on the truck, the pick up rivet may be touching the inside of the truck. If the tender was handled rough, it bends down the truck frame and shorts on the rivet. Either add a piece of electrical tape on the truck frame, or straighten the truck frame so the rivet has clearence.
