Ribbed for neutral wire.

The larger pronged, ribbed wire goes directly to the neutral on the transformer. The smooth (hot) side of the wire is soldered to the fuse holder, which goes on to the transformer.

Hi BanditBoy
I am German speaking, living in Switzerland, the "Wall-Outlet" gives us "Line-current of 220 VAC". You have 110 VAC ? Or also 220 VAC ? We have a simple "Test-Tool" - in the dix I find "Charge Indicator, Circuit Tester, Strain gage, Voltage Detector, Voltage Tester". A picture: https://de.wikipedia.org/wiki/Phasenpr%C3%BCfer#/media/File:Phasenpruefer_01-l_KMJ.jpg - If I push the tip of this little Screwdriver into the Wall-Outlet and put my thumb onto the other end of the Screwdriver -> if I push it into "POWER-Side": The little bulb inside the Screwdriver lights up telling me "ThIS IS POWER-LIFE-CONNECTION".

When You rewire the Line-Cord: The POWER-Life-Cord should run through the Toggle-Main-Switch and through the "High-Volt-Power-Fuse".
The pin runs "This way" or "The other Way" mounted (Life-Wire / Neutral-Wire) - BUT: Fuses should be in the POWER-LINE - a fuse should blow when "too much Power gets in" - NOT: "Too much Power gets in , runs through the transformer - and still "Too much" flows through the Neutral-wire back to the Wall-Outlet". Double-check for correct mounting !!!
