As a result, I have devised a simple procedure that anyone may follow to achieve excellent outcomes.
Things you will need to troubleshoot the lawn mower lights not working:
|Clip-on Meter Probes||Voltmeter|
|Safety gloves & Goggles|
Step-1: Replace the Lightbulbs
Removing and replacing the old bulb is the quickest and most straightforward approach to verify that the light is working properly.
It is possible that your existing bulb was defective or burned out, in which case a new one will need to be installed in its place. To do that-
- Firstly, rotate the headlight socket on your riding mower to remove it by lifting the hood.
Note: Make sure to put the key in the ignition and turn the key off.
- Then remove the old bulb by twisting it and pulling it out. To fasten the replacement headlamp, insert it into the socket, then turn it clockwise to lock it into place.
- The socket in the headlight housing needs to be realigned and rotated to secure it.
- To see if your new bulbs are working, check them out.
- If not, then there may be a problem somewhere else. If the new one works, there must be a problem with the old one. Lower the hood after the repair is complete.
Step-2: Examine the Switches
The switch controls the power of the bulb. A broken switch causes nonworking lights.
To examine the switch, follow the procedure given below:
- Connect a volt meter to the switch, turn it on, and look for 12 volts.
- If you do not observe 12 volts, connect the volt meter’s positive wire to the switch and the negative lead to the battery.
- If the volt meter displays 12 volts, the switch has power. If the lights do not work, the switch is defective and needs replacing.
- Locate the switch and depress the tabs to remove it. Remove the wires, attach them to a new switch, and test the lights.
Step-3: Modify the Wiring Harness.
The wiring harness connects the battery, switch, and bulb. A damaged or malfunctioning harness can affect your tractor’s lights.
Follow the given step-by-step guide to modify the wiring harness:
- Attach a voltmeter to the harness to check for 12 volts. Repeat with all connectors and check voltage.
- Check the plug or socket for damage after locating the voltage drop.
- Check connectors for loose wires. If they are up to the mark, examine the wiring.
- Look for a break or anything causing the wiring to ground out. Electrical tape can mend minor wire damage.
- If a plug or socket is destroyed, splice in a new one using crimp able spade connectors. You can also twist and solder the wires, then protect them with heat shrink.
Step-4: Examine the Sockets
The socket holds the light bulb and allows power to pass through it. If the socket’s connectors are bent, missing, or otherwise damaged, it must be replaced.
To examine the sockets, follow the procedure given below:
- Lift the hood, turn the socket clockwise, and then cut the wires to replace it.
- Next, strip a harnessed wire to make the new connection.
- Heat shrinks the wires, attach the new socket, then solder the wires together. Crimp on male and female spade connections. Heat shrinks the connector with a lighter or small torch to create a moisture-proof seal.
Note: Please be aware that this is a comprehensive guide to fix. You should consult the manual that was given to you by the previous owner for additional particular repair advice relevant to your model.
