John Deere Maintenance Monday: Diagnosing light problems
Check the fuses
Radio interview source: Blake Barnes, group product marketing manager, John Deere
In this edition of Maintenance Monday, Adam from South Carolina says he's been having a problem with the lights on his utility tractor not coming on, and he's not sure what to check first.
Blake Barnes is a product manager with John Deere. He says to make sure the tractor doesn't have any problems starting. If the machine has been in storage for a while, it's possible the battery is disconnected.
If you have power, the next step is to check the fuses.
"Consult the operator's manual, and try to verify what fuse is controlling your lights," Barnes says. "So, it will be headlights, it could be your working lights or your rear lights, so you just want to verify what fuse it is and see if the fuse happens to be blown. That would be indicative of what is creating your problem."
It's important to replace blown fuses with those of an equal amp rating. Most utility tractors use headlight and taillight lamp fuses around 20 amps, and flasher and warning light fuses of 15 amps.
Examine all the light bulbs for cracks or broken filaments. Always wear gloves or use a clean cloth to handle the bulbs, as the oil from your fingers can create a hot spot on the glass and cause the bulb to fail.
