Review KENT MOORE Extremely Rare Parasitic Draw Test Switch New Old Stock

The Kent-Moore J-38758 Parasitic Switch is a versatile and reliable solution for managing electrical circuits in various applications. This switch, manufactured by Kent-Moore, a leading brand in the automotive aftermarket, is designed to provide easy and effective control over parasitic drains, ensuring optimal battery performance.

The J-38758 switch is a compact and durable device, constructed with high-quality materials to withstand the rigors of everyday use. It features a robust, die-cast housing that protects the internal components from damage and the elements, while its weather-resistant design enables it to function reliably in various environmental conditions.

This switch operates on a simple yet effective principle: it allows the user to connect an accessory or device to a circuit without draining the battery when the vehicle's ignition is off. The J-38758 switch is particularly useful for powering accessories like alarm systems, GPS units, or backup cameras, which require a constant power source but should not drain the battery when the vehicle is not running.

To use the switch, simply connect the accessory or device to the switch's constant power (positive) and accessory (switched, negative) terminals. The switch will automatically disconnect the accessory from the battery when the vehicle's ignition is off, preserving battery life. When the ignition is turned on, the switch connects the accessory to the battery, ensuring it functions as intended while the vehicle is running.

The J-38758 Parasitic Switch comes with easy-to-follow instructions for installation, making it a straightforward addition to any electrical system. Its compact size, along with its dependable performance, makes it an indispensable tool for anyone looking to maintain optimal battery health and keep their electrical accessories functioning at their best.

The Kent-Moore J-38758 Parasitic Switch is a device designed to help diagnose and troubleshoot electrical systems by allowing users to monitor and control parasitic drain. Here are some potential pros and cons of buying this parasitic switch:

Pros:

1. Diagnostic Tool: This device can help identify parasitic drains in electrical systems, which can save time and money in the long run by preventing unnecessary repairs or replacements.

2. Easy to Use: The parasitic switch is relatively simple to use and can be installed in a short amount of time. It does not require any special tools or expertise.
