Step-by-Step Guide to Ramsey Winch 2 Solenoid Wiring Setup

Start by identifying the four primary connection points on the relay assembly: two large terminals for the power feed and two smaller terminals for the control circuit. The positive (+) input from the battery should attach to the first major post, while the outgoing power lead connects to the second large terminal. Verify that the cable gauge matches or exceeds the manufacturer’s specifications–typically 2/0 AWG for 12V systems–to prevent voltage drop under load. Mistakes here will cause overheating or premature failure.

For the activation circuit, wire one small terminal to the switch lead (momentary or maintained, depending on the setup) and the other to a ground reference. Use 16-gauge copper wire or thicker for reliability. If integrating a wireless remote or auxiliary control, splice the signal wires directly into these terminals–ensure polarity is correct, as reversed connections can damage the switching mechanism. Test continuity with a multimeter before applying power.

Add a 40-amp circuit breaker or fuse inline with the positive battery cable to protect against shorts. Install it within 7 inches of the battery to minimize exposed cable length. For extended pulls or continuous duty, mount the relays in a ventilated enclosure to avoid heat buildup–ambient temperatures above 120°F degrade performance. Label each wire with heat-shrink tubing to simplify troubleshooting later.

When running the setup, monitor for voltage sag at the motor during operation. If readings drop below 10.5V under load, upgrade the battery or reduce resistance in the cables. For dual-direction control, verify that the relays alternate correctly–both engaging simultaneously will short the system. Use a relay tester or manual switch cycling to confirm proper sequencing before field use.

Guide to Connecting Dual Relay Systems in Heavy-Duty Pulling Equipment

Begin by securing the positive terminal from the vehicle’s battery to the central contact of the first relay unit using 4 AWG cable–this ensures minimal voltage drop during peak load conditions. Confirm the connection is crimped with a marine-grade lug and sealed with heat-shrink tubing to prevent corrosion under harsh operating environments.

Attach the output side of the first relay to the input of the second unit using identically rated cable. Verify polarity alignment before fastening terminals; reversing connections here will cause the directional controls to malfunction. For systems rated above 9,500 lbs, substitute 2 AWG cable to accommodate higher current draw without overheating.

• Trace the trigger wires from the controller: the first wire engages forward motion, the second activates reverse, and the third (if present) is for momentary power-off braking.
• Connect each trigger wire to its corresponding relay coil terminal–use spade connectors for quick servicing but solder joints for long-term reliability in off-road conditions.
• Insulate all connections with dielectric grease before securing them to prevent moisture ingress.

Ground both relay units at a single chassis point near the mounting location to avoid ground loops. Use a self-tapping bolt (minimum #10 gauge) into bare metal, ensuring the surface is sanded to remove paint or oxidation. Poor grounding will cause erratic operation or complete failure, especially in high-amperage applications.

Test the circuit with a multimeter set to continuity mode before applying power. Check that each relay clicks when the controller is actuated, and measure voltage drop across the contacts–any reading above 0.2V indicates a loose connection or undersized cable. Repeat the test after simulating a 50-foot pull to validate performance under load.

1. Route all cables away from sharp edges or moving parts–secure with zip ties every 6 inches to prevent chafing.
2. Label each wire at both ends for future troubleshooting.
3. Install a 30A circuit breaker inline with the main power feed to protect against short circuits.

For systems with wireless remote options, pair the receiver to the controller per the manual, then verify that the signal strength remains stable within the equipment’s rated operational range (typically 50 feet). If interference occurs, relocate the receiver away from other electronic devices or use a shielded cable for the antenna lead. Always store spare fuses and relay contacts in the equipment’s toolbox for field repairs.

Locating the Proper Activation Points for Electrical Connections

Start by tracing the heavy-gauge cables from the power mechanism to the control assembly. The two larger posts handle the main current flow–one connects to the battery’s positive terminal, the other to the motor’s input. These posts are typically marked with ⁰⁄₈ or M6 threads and occupy the outermost positions on the contactor block. Verify polarity using a multimeter: the post showing zero resistance to the battery lead is the primary input, while the one registering continuity with the motor is the output. Reverse these feeds and the device will rotate backward or refuse to engage.

The smaller auxiliary posts govern direction switching and require precise pairing. Look for embossed labels: A1/24 or S1/S2 on older units, B+/B- or IN/OUT on newer variants. Connecting mismatched pairs risks short-circuiting the relay coil or creating a parasitic draw that drains the battery within hours. Always cross-reference the marking scheme with the original equipment schematic–never assume color codes match factory defaults aftermarket modifications often alter them.

Test engagement before final fastening: apply 12V briefly to the control posts–audible clicking confirms correct terminal identification. Absence of response suggests either a defective relay or reversed connections. Recheck using a 12V test light; if the indicator illuminates but no click occurs, the internal coil may be open-circuited. Secure all terminal nuts to 8-10 Nm torque–loose fastening causes transient voltage spikes that degrade contact surfaces over time.

Color-Coded Connections for Dual-Coil Control Assemblies

Locate the heavy-gauge red lead first–this is your primary power feed from the battery’s positive terminal. Secure it to the larger stud on the control block marked “BATT” or “+” with a crimped ring terminal and a split washer; torque to 12–15 Nm to prevent corrosion-induced voltage drop.

Attach the black ground strap to the nearest chassis point. Use star washers and M8 stainless hardware; avoid tapped holes in aluminum cross-members–prefer welded steel tabs for consistent conductivity. Verify clearance to moving parts; a minimum 15 mm gap prevents chafing.

Small-Wire Circuit Routing

Strip the blue control cable 8 mm, insert into the smaller “S1” or “UP” spade terminal, and bend the exposed strands backward before crimping. Repeat for the green “S2” or “DOWN” wire. If the controller box lacks labeled studs, consult the date code: pre-2020 units use blue/green; post-2020 kits swap to orange/gray.

Route auxiliary circuits–white/red and white/green–directly to dash-mounted rocker toggles, bypassing inline fuses under 10 A. Keep runs parallel to OEM harness bundles to reduce EMI; coil excess wire into 50 mm loops instead of sharp bends.

Tie remaining white or brown return lines to chassis ground; polarity is critical–reverse hookup energizes the internal relay without manual activation. Use dielectric grease on every terminal to seal against road salt and brake dust ingress. Final resistance check: motor-side coils should read 2.3–2.8 ohms at 20 °C; readings outside this range indicate internal shorts.

Common Errors in Hooking Up Pulling Device Actuators

Incorrect polarity during installation leads to immediate actuator failure. Always verify terminal markings before attaching cables–positive and negative connections must align with motor specifications. Reversing them burns internal coils within seconds, requiring expensive replacements. Test with a multimeter first if markings are faded or unclear.

Skipping relay checks creates unnecessary wear. Actuators designed for intermittent duty overheat when forced to run continuously. Install a secondary switch to break the circuit between pulls, extending component lifespan by 40-60%. Factory default relays often lack this protection.

Overlooking ground quality causes intermittent power loss. Corroded chassis connections create resistance, reducing torque by up to 25%. Sand contact points bare metal and apply dielectric grease to prevent oxidation. Avoid relying on factory paint as a conductive path.

Ignoring voltage drop measurements during load testing skews performance expectations. Wire gauge must match expected amperage draw–undersized cables introduce resistance, decreasing pulling force under load. Use 1/0 AWG for 10,000lb-rated devices and measure drop across connections under full strain.

Misaligning contactor actuation timing damages both tractor units and remote boxes. Trigger mechanisms should engage smoothly without physical binding. Check for proper plunger travel distance–excessive force warps mounting brackets, causing misfires after repeated cycles.

Underestimating environmental exposure accelerates corrosion. Saltwater and mud splatter penetrate plastic housings within weeks if unsealed. Apply conformal coating to internal boards and housing edges during installation. Rotate components weekly in humid climates to prevent condensation buildup.

Disregarding noise suppression creates electrical interference. Unshielded starter relays radiate RFI, disrupting onboard electronics. Install ferrite cores on power leads and route cables away from ECUs. Capacitance across motor terminals reduces voltage spikes during disengagement.

Failing to document modifications complicates troubleshooting. Label each cable segment with voltage, gauge, and purpose. Photograph assembly steps before closure–missing a single connection renders entire systems inoperative after maintenance. Reference manufacturer torque specifications for terminal screws to prevent loosening under vibration.
