SKU: SMA-141-140F 14 AWG Black Primary Wire - 15 Foot Cut for Tractor and Equipment Electrical Repairs

When you're troubleshooting electrical problems on your tractor or equipment, nothing beats having the right wire on hand. Whether it's a dead work light, faulty gauge, or burned-out connection, this 14 AWG black primary wire gets power flowing again. The black insulation makes it perfect for ground circuits or when you need to blend repairs into existing harnesses without standing out.

What You're Getting

• Heavy-duty 14 gauge stranded copper wire handles 15-20 amp loads without heating up
• Durable GPT insulation resists oil, fuel, and weather - won't crack in cold weather or get brittle in summer heat
• Smooth surface pulls easily through factory looms and protective tubing
• 15-foot length gives you enough wire for most cab and engine compartment repairs
• Single conductor design keeps things simple for point-to-point wiring

Built for Real Farm Work

This wire is built to handle the demands of agricultural equipment where vibration, moisture, and temperature swings are part of daily life. The 14 gauge size is perfect for powering work lights, powering accessory circuits, and making ground connections on tractors, combines, and implements. It's the same spec wire that OEMs use in factory harnesses.

Made to Last

The stranded copper core stays flexible even after years of vibration, while the thermoplastic insulation holds up to diesel fuel, hydraulic oil, and wash-down water. This isn't hardware store automotive wire - it's built to meet the tougher standards that farm equipment demands.

Installation Notes

Always disconnect the battery before working on electrical systems. Use proper crimp terminals and heat shrink tubing for connections that'll last. When running new wire, secure it every 12 inches and keep it away from sharp edges and moving parts. A little dielectric grease on terminals prevents corrosion down the road.
