Testo:

What you describe seems, some overload protection is tripping. Removing and reconnecting power supply to its load (MacBook) is needless, because power supply remains in tripped / shutdown state. Substituting AC connection ("duck head" or cord) is needless, because form of AC connection is not important.
 
''''I installed a replacement wire instead of keeping the old one.''''
 
Do you know, what kind of replacement? What specific type of MagSafe tip/plug? If your plug identifies as 60W or 85W, then it is no wonder that your 45W supply is overloaded. You can use 'System Information.app' (or 'System Profiler.app') to find your plug's identity. In section 'Power',Open 'System Information.app', view 'Power' (subpage of 'Hardware'), look under heading 'AC Charger Information:', whatInformation:'. What 'Wattage (W)' is reported?
