Default Testing Ford Philco AM Push Button Radio

I just bought an original AM push button radio for my Mustang.

I need to test this radio and need help in the wiring connections.

There are two sets of wires coming from the radio. One set is blue with red stripe that goes to a bulb, and yellow with black stripe that goes into radio. The other set is black, and black with green stripe - both go into radio.

I want to connect radio to 12V power and a car speaker I have. I have a 120 volt ac power converter that will convert to 12V DC. It has positive and negative leads.

Can anyone give me some help with the connections? Thanks.

I've looked at some Ford wiring diagrams but am still lost.

Thanks. I didn't have an antenna attached when I tested it, but all I got out of the speaker was a hum so I guess the radio needs repair.

a converter may generate a lot of hum. Without an antenna the AGC (auto gain control in the set) will turn itself way up and pickup all sorts of noise since there is no signal. Stick an unbent coat hanger with the paint scraped off the end, in the antenna hole, make sure it doesn't touch the radio housing and unless you are 100 miles from a city you should get something if the radio works.

Installed it in car with antenna and speakers, went out to an open area, only picked up one station somewhere between 1400 and 1600, adjusted the trimmer screw and lost the station. Adjusted screw back to original position and couldn't retrieve the station again. Know anybody who works on these?

Would it have been common for a radio with a 67 part number to be placed in a 68? My 68 rolled off the assembly line March 14, 1968, according to Marti report.

Ford is famous for using up whatever they have left over in the parts bin so it wouldn't surprise me. Or maybe back in the day it was warrantied out and replaced with a 67 by the dealer.

Hard telling.

Those old radios probably need most of their capacitors replaced and maybe some of the coils. Even at best, they picked up lots of ignition noise and were not very sensitive. Unless you are really trying to make it 100% original you would be better off with a new radio. We put a USA-1 from Custom Autosound in a '67. The rear package shelf has speaker locations built in by the factory. We used a dual speaker in the front which used the center dash pad location, and it sounds very good.
