If you've ever found yourself stuck in a challenging off-road situation, you know the importance of a reliable winch in your 4WD. However, proper wiring is often overlooked. In this comprehensive video tutorial complilmented by key takeaways below; we'll break down the important steps we take to ensure the winch is not only installed but also wired correctly.

Klarmann Automotive Solutions, experts in off-road auto electrics, share their insights on the best practices for wiring up a winch, including a bonus tip for an 'Get Home Safe' setup.




Key Takeaways:


  1. Importance of a Winch Isolator:
    • Klarmann Automotive Solutions emphasizes the significance of a good quality winch isolator for proper wiring.
    • We recommend to wire the winch to your start battery positive through an isolator
  2. Battery Isolation and Solenoid Choice:
    • Use a robust 300-amp continuous duty isolator to prevent issues under high load.
    • Avoid flimsy plastic isolators, as they can melt and malfunction during extended winching.
    • If going for a remote-controlled solenoid, choose one with a minimum rating of 300 amps, or preferably 400 amps for prolonged winching sessions.
  3. Battery Wiring and Grounding:
    • Connect the battery negative directly to the start battery negative.
    • Ensure positive and negative cables from the start battery go directly to the winch.
  4. 'Get Home Safe' Setup:
    • Klarmann recommends a Redarc SBI12 solenoid for an additional battery setup.
    • The solenoid automatically connects and disconnects the second battery based on engine status.
    • Leaving the car in high idle, will allow your alternator to create more charging power, have both batteries linked via a constant switch and have both powering your winch
  5. Optimal Power Distribution:
    • Klarmann's expert wiring ensures direct power to the winch from three sources: alternator, start battery, and secondary battery.
    • This setup guarantees ample power for the winch, even in situations where battery voltage drops.
