How To Wire A Winch Without A Solenoid -Step by Step Guide

All the clumsy folks out there learn how to wire a winch without a solenoid! It could prevent you from dramatic accidents.

When the motor winch is switched on, a solenoid is an electrical switch that accepts power from the truck battery and powers the motor winch. Depending on the winch design, solenoids may be installed inside or remotely. It may also depend on some more factors like available installation space. When an electric current flows across the wire, it creates a consistent magnetic field. The cables operate as switches, as seen in the wiring schematic for a winch solenoid.

Solenoids’ primary function is to relieve strain on the winch’s switch. It also prevents overheating.

Guide On How To Wire A Winch Without A Solenoid – Step By Step

In mechanics, you must have a clear vision of what you aim to do. Not only does it, but you should emphasize the purpose and expected outcome. A winch solenoid wiring diagram might assist you throughout this step by illustrating the motor’s construction. You may get a visual depiction of your winch from the manufacturer or another technician with expertise in that kind of winch.

Phase – 1:

The winch mechanism is operated by twisting a knob, which makes it simple to maneuver. The next step needs you to set the winch in a free spool, which is likely to be driving in neutral gear on a vehicle. Prior to using this mode, check that the winching mechanism is not loaded to avoid an accident.

Phase – 2:

Disconnect the terminals from the battery, beginning with the positive lead and working your way down to the grounded lead. It is wise to mark the wires on the schematic to prevent any misunderstanding that might result in erroneous results. Three poles next to the motor should be labeled A, F1, and F2.

Phase – 3:

Bring your jumper wires with you for this phase because a 5, or 6-inch cable will suffice. You’re now going to run the line from A to F1 and connect it to the battery through F2. Once this connection is confirmed, the winch motor should only operate in one direction.

How are the A and F2 posts used to connect the motor to the power source? Rep with the B and C posts to start the engine operating on the other side as well.


  • How does a solenoid work?
  • A solenoid is a coil of wire that functions as an electromagnet. Additionally, it refers to any device that converts electrical energy to mechanical energy through a solenoid. The device generates a magnetic field from an electric current that ultimately produces linear motion. Click here to learn…more

  • Are all winch solenoids identical?
  • Two solenoids are used in certain winches, whereas four are used in others. A permanent magnet winch normally has two solenoid setups. They are less powerful, less dependable, and more affordable. Four solenoid layouts are more powerful, dependable, and lightweight.

  • How to test a winch solenoid?
    • Double-check the winch solenoid and battery cable connections.
    • After detaching the positive (red) winch wire from the battery, unscrew the solenoid cover.
    • With the winch turned off, connect a voltmeter to the big studs on the solenoid.
  • How to wire from winch to solenoid through the switch?
    • Connect the winch motor’s positive and negative wires to the solenoid.
    • Connect the positive and negative battery wires to the battery-specific solenoid terminals.
    • Connect the battery lines from the solenoid to the car battery, and make sure that they are connected to the proper polarity terminals.
  • How can you get around a winch solenoid?
  • What you need to do is to connect “A” to “F1″ using a tiny jumper wire (5″-6” dead wire, 8 gauge would enough) and connect “F2” with the battery (jumper cables will suffice). At this point, the winch motor should only be turning in one direction. Set the battery to “F1” and connect the jumper from “A” to “F2.” Learn here more about winch solenoid.

  • Why isn’t my winch working?
  • Damaged or corroded contactor might be the cause.

    If the winch operates properly when powered by flying leads, the issue is almost certainly with the contactor. Although the solenoids light up, they are not connected. It might be the cause of corrosion or thermal damage

  • Will a winch drain my battery?
  • No, if the winch isn’t operating, it won’t deplete the battery. The first step is to double-check that your cords are secure. However, it’s conceivable that your battery has failed.

  • How to wire a winch to a battery?
    • Connect the winch’s positive wire to the vehicle’s positive terminal, using an in-line circuit breaker if one is equipped with the winch.
    • Connect the winch’s negative wire to the car battery’s negative ground terminal.
  • What is a reversing solenoid?
  • A single package containing two solenoids saves costs and maximizes space savings while simplifying wiring. For permanent magnet motors, two integrated solenoids enable dynamic braking. More information is available.

  • Why does my winch rattle?
  • The clicking solenoid simply indicates that the coil is in good working order and pushes the contacts together. Dirty or pitted contacts, or a faulty connection to one or more solenoids, might be preventing electricity from reaching the motor winch.

  • Does a winch need a relay?
  • The solenoid above the winch controls the amount of power pulled from the battery. In addition, it must decide the direction in which the motor will revolve, among other things. It is not necessary to use a relay. You may use it to add an on/off switch to your dashboard.

  • How to bypass a solenoid?
    • Look beneath the car for the starting motor.
    • Locate the two metal connections on the starting solenoid’s backside.
    • Cover the two metal contacts with the metal blade of an insulated screwdriver.
    • Enlist the assistance of a friend to start the engine using the key.
    • Listen to the start.

    Final words

    After being introduced to the topic, please go through each step slowly to ensure you get the most out of the maneuver! It usually takes time to master a new approach, which is perfectly acceptable, particularly if mechanics is not your thing. Slowly and methodically, you will explore the world of mechanics with a smile on your face!
