Coil Test: Strip off clear insolation on ends of coil wires with a multi meter on the 200 OHM settings check resistance. A good coil will have a resistance of about 8.8 OHM.
If it is much less your coil is shorted and will not generate enough magnetic field to uncouple. (Leaving the uncoupler active for to long cause coil to over heat melting the insolation and shorting out the coil.)
Magnetic Field Test: Before installed in track. With momentary switch activated take a piece of steel and it should sticks across both field plates.
