Okay. You are starting from the beginning, and we all did at one time!! There books out there that deal with the restoration of antique radios that are mentioned in other threads on this phorum. I would suggest your search and educate yourself as much as possible. It is a very rewarding experience. Take this project slowly.
Unfortunately, time has eroded the clear delineation of colors in these old radios. Many wires that were once various colors, now look similar. Let's start with the transformer primary. The service info says both wires coming from the primary were once white. These 2 wires will go to the power cord. One directly, and the other through the power switch. Put your meter probes on these 2 connections coming from the power transformer and measure the resistance. It should be about 4 ohms.
I can't tell much from your pic. Not sure what I'M looking at since I've never worked on this model. The 2 yellow wires from the power transformer should go to pins 4 and 6 of the 5Y3 rectifier tube. The resistance between those 2 pins should be about 520 ohms. there will be a little variation. Let's start there and see what we've got.
