Real-World Testing: Putting Sierra International 185705D Power Trim Relay Display Packed to the Test

My testing environment for this power trim relay was primarily my home workshop, a space that sees a fair amount of dust, oil, and the occasional unexpected splash of coolant. The immediate application was integrating it into the power trim control circuit for a hydraulic lift table I use for heavier engine work. This involves repeated actuation of the trim up and down functions, demanding consistent electrical switching under moderate load.

First Use Experience

The initial installation was straightforward, a testament to its standard 5-terminal design. I connected the wires according to the existing harness, ensuring a snug fit on each terminal. Flipping the switch for the first time brought a satisfying click, and the hydraulic pump whirred to life, lifting the platform smoothly. I cycled the lift up and down perhaps a dozen times within the first hour, testing its responsiveness and ensuring there was no hesitation or erratic behavior. The conditions were typical workshop fare: ambient temperature, a generally dry environment, and no exposure to extreme elements. It performed precisely as expected, a welcome change from previous unreliable parts.

Extended Use & Reliability

Over the subsequent weeks, this relay became an integral part of my daily workflow. The lift table was used almost every other day, meaning the Sierra International 185705D Power Trim Relay Display Packed was actuated dozens, if not hundreds, of times. It handled the continuous switching of the power trim motor without any discernible degradation in performance. There were no signs of overheating, no flickering of the motor’s operation, and crucially, no unexpected failures.

Durability has been impressive. I haven’t noticed any cracks, stiffness in the internal mechanism, or performance drops. The plastic housing feels solid and has resisted minor bumps and scuffs that are inevitable in a busy workshop. Maintenance has been minimal; a quick dusting off is all it’s needed. Comparing it to the generic, often unrated, replacements I’ve used in the past, this Sierra International unit stands out for its sheer consistency and robust feel. It’s a component that simply works, day in and day out, without requiring constant attention or worry.

Breaking Down the Features of Sierra International 185705D Power Trim Relay Display Packed

Specifications

The Sierra International 185705D Power Trim Relay Display Packed is a Single Pull, Double Throw (SPDT) relay, a crucial design that allows it to switch a single input to one of two output circuits. This is fundamental for applications like power trim, where you need to direct power to a motor to move in one direction or the other. The specifications detail its electrical capabilities: a Closed Contact rating of 20 Amps for Resistive loads and 15 Amps for Inductive loads.

This distinction is important; inductive loads, like electric motors, draw significantly more current when they first start up. The Open Contact rating jumps to 40 Amps for Resistive and 30 Amps for Inductive loads, which signifies its ability to handle higher surge currents or momentary loads when the circuit is open. It operates on a standard 12-volt system, common in automotive, marine, and workshop equipment. The relay features 5 terminals, typical for an SPDT configuration, making it compatible with a wide range of control circuits. The fact that it comes “Display Packed” implies it’s intended for retail display, suggesting a level of quality and presentation.

Performance & Functionality

In its primary function of controlling the power trim on my hydraulic lift, this relay performs exceptionally well. The transition between lifting and lowering is immediate and decisive, with no perceptible lag or ‘chattering’ of the contacts. Its ability to handle the 15 Amp inductive load rating comfortably is evident; the motor starts up smoothly every time. The higher 40 Amp resistive and 30 Amp inductive open contact ratings suggest it’s built to withstand the electrical demands of such systems without prematurely failing due to surges.

Its main strength lies in its reliability. It consistently performs its switching duty without fail, which is precisely what you need in a component that underpins the operation of heavier machinery. A potential weakness, though not directly observed in my use, could be the limitations of its amperage ratings for extremely high-power systems. For a standard power trim application, however, it hits the sweet spot. It meets, and in my experience, slightly exceeds expectations for a replacement part in this price range.

Design & Ergonomics

The design of this relay is functional and straightforward, as one would expect from a component primarily focused on electrical switching. The housing is made of a durable, high-impact plastic that feels substantial and capable of withstanding workshop abuse. The terminals are well-machined and provide a firm connection for standard spade connectors.

Ergonomically, it’s a component that you install and then largely forget about, which is the ideal scenario. There are no intricate controls or fiddly bits to manipulate. The 5-terminal layout is standard and intuitive for anyone familiar with relay wiring. The crisp ‘click’ when the coil engages is a satisfying auditory cue that the switching action is occurring. Its straightforward design ensures there’s no real learning curve; it’s plug-and-play for its intended application.

Durability & Maintenance

Based on my extended use, the durability of the Sierra International 185705D Power Trim Relay Display Packed appears to be excellent for its intended application. It’s designed as a reusable component, and so far, it shows no signs of wear or impending failure. For a typical power trim system in a workshop or marine environment, I would expect this relay to last for many years.

Maintenance is virtually non-existent. The plastic casing is easy to wipe clean of dust and grease. There are no user-serviceable parts internally; it’s designed to be replaced as a unit if it ever does fail. A potential point of failure, common to all such relays, would be corrosion on the terminals if exposed to moisture for prolonged periods without protection, but the housing itself seems well-sealed against incidental splashes.

Accessories and Customization Options

This Sierra International 185705D Power Trim Relay Display Packed comes as a standalone unit, meaning there are no included accessories or built-in customization options in terms of interchangeable parts. Its strength lies in its direct replacement capability for existing 5-terminal SPDT 12V relays.

However, its standard terminal configuration means it’s highly compatible with common automotive and marine wiring connectors and harnesses. While not a direct accessory, ensuring you have the correct gauge wire and secure crimp connectors for the terminals is essential for optimal performance and longevity. For some specialized applications, one might consider adding a small weatherproof cover if it’s mounted in a particularly exposed area, though the housing itself offers reasonable protection.
