Narrative:

Flying IFR flight plan between deer park and kennedy vors, lost radio and electrical navigation equipment. I continued flight plan route staying west of airway over low overcast to broken to scattered poor visibility below. Good visibility at 6000 ft coming up on the new jersey shore. I descended to 4000 ft which I had on many prior flts been instructed to do by new york departure. New york approach tried to contact me and the controller realized I had a radio failure. I could hear him on my hand-held but apparently he could not hear me. When further away from new york airspace, I naved with hand- held toward pne. I checked my fuel and switched tanks. Fuel would be no problem. I turned on and off the alternator and left switch on. Sometime later, the navigation/communication came up. I called phl approach and told the approach controller bout my navigation/communication failure. He gave me altitude instructions and cleared for ILS 24 approach which I flew in and landed without further incident.
