overheating solenoid

Gregcz1OGR Forum Member

I am refurbishing a Standard Gauge #10E which has a "pendulum" reversing unit. As I am tested out everything and rewiring the unit, I notice the reverse unit was getting hot without any sign of a short. After activating the solenoid for about 15 seconds, it gets really hot and smoke can be seen coming out of the top of the unit.

I have taken the unit apart and check for crossed wires at the top but there are completely separated. Even with the plunger taken out it still gives the same result.

I can't tell if something is wrong with the wire wrapped around the unit because it is covered.

Thoughts?
