How to Wire Tractor Lights
If your tractor needs more light, either in the back or the front, you can install additional lights with little problem. The tractor’s battery will power the lights after you attach the lights' wires to the magnetron. The magnetron is the tractor’s generator. You can wire lights directly to a battery, allowing you to run the lights when the tractor's motor is off. Wiring lights to the magnetron means the lights will work only when the tractor is powered on.
Put on gloves and open your tractor’s hood. Find the black and white wires attached to the magnetron. These are the alternating current wires. These wires are connected to the magnetron on only one end; the other end of each wire is either loose or bound to the other with wire tape. Remove the wire tape from the black and white wires if they're attached.
Peel back the plastic by 1 inch, using the wire strippers, on the loose ends of both wires.
Locate the light switch. It will be between the starter and distributor and below the fuse and ignition switch on your tractor. Wrap the black wire around one terminal on the light switch. Wrap the white wire around the other terminal on the light switch. Screw a nut onto each terminal post to secure the wires between the nuts and the bases of the terminal posts.
Connect one of the tractor light’s wires to the “A” terminal on the light switch. The "A" and "B" terminals will be labeled. Peel back the sheathing from the wire and wrap the wire around the terminal to connect it. Screw another nut onto the post to secure the wire.
Connect the other tractor light to the light switch’s “B” terminal. Screw another nut onto the post to secure the wire.
Wire the tractor lights together: Place the terminal “A” wire from the second light into the “A” terminal in the first light. Place the terminal “B” wire of the first light in terminal “B” of the second light. Use a terminal nut to secure the wires if necessary.
You can secure all wires on a single terminal with a single nut if you prefer.
