[QUOTE="chrisc, post: 848222, member: 746"] First of all, the plastic wheel is [b]missing out the top of the strike[/b]. This needs to be in, to push in the top bar so as to tension the spring. Btw, take out the copper pin in the slot in the middle. Just press in the bolt and use needle-nose pliers Still not working? Place a meter probe set to 20 VDC (or AC, depending on what the power supply provided) on the two soldered lugs at the bottom of the coils. Then get someone to press the release button for 10 or so seconds Voltage present - either an improper connection to the coil, or the coil has gone open circuit No voltage present - take out both wires and hold them on the meter probes and repeat the release button. You won't get a shock since the body cannot detect anything under about 60 volts With the wires out, you can see the little copper strips which you need to lift up to align with the holes in the plastic. Set the meter to 200 ohms and check for continuity (about 8 to 10 ohms) [/QUOTE]
