  • Handy too!
Recently diagnosed a bad starter. The vehicle’s system tries to crank for several seconds. This made it to where I could crank and immediately stop if some started smoking, lol. Beats using a paper clip.

The RVMARINEPAT Relay Bypass Switch Kit is a diagnostic and testing tool designed to streamline the process of testing and bypassing relays in various vehicles. Here’s a comprehensive review of its features, benefits, and potential drawbacks: Pros: Versatile Compatibility: Wide Application: The kit is compatible with a range of vehicles including domestic GM models, BMW, Audi, and Chrysler. This broad compatibility makes it a useful tool for a variety of automotive applications. Comprehensive Kit: 6-Pack Includes: The kit includes multiple relays and bypass switches, which provides a comprehensive solution for testing and diagnosing relay-related issues. Having several components on hand can be convenient for addressing multiple scenarios or working on different vehicles. Diagnostic Functionality: Relay Testing: The relay tester function allows you to check the functionality of relays, helping diagnose issues related to electrical components. This can be particularly useful for identifying faulty relays without the need for trial and error. Fuel Pump Relay Bypass: Fuel Pump Testing: The kit includes components specifically for bypassing the fuel pump relay, which can be essential for testing fuel pump functionality or diagnosing fuel delivery problems. Replacement for Multiple Parts: Replaces 9036 and 9037: This kit serves as a replacement for specific relay part numbers (9036 and 9037), making it a versatile tool for users who need to work with these particular relay types. Diagnostic Scan Tool Integration: Scan Tool Capability: The inclusion of a diagnostic tester/scanner enhances the kit's functionality, allowing for more detailed analysis of relay and electrical system performance. Cons: Complexity for Novices: Learning Curve: While the kit provides valuable diagnostic and bypass functionality, it may have a learning curve for those unfamiliar with relay systems and electrical diagnostics. Understanding how to use each component effectively requires some technical knowledge. Potential Overlap: Redundancy: For users who primarily work with a specific type of vehicle or relay, the inclusion of multiple relays and bypass switches might lead to redundancy. Some components may not be used frequently, depending on the user’s needs. Durability Concerns: Build Quality: The durability of the components can vary. Users should ensure that the kit is well-built and suited for repeated use in a professional or DIY setting. It's advisable to inspect the quality of each component before use. Compatibility Limitations: Specific Vehicle Focus: While the kit is compatible with a range of vehicles, it might not cover all possible relay types or vehicle models. Users with less common vehicles or specific relay needs should verify compatibility before purchase. No Detailed Instructions: Usage Guidance: The kit may not come with detailed instructions or guides on how to use each component effectively. Users may need to refer to external resources or seek professional advice to fully utilize the kit. Overall: The RVMARINEPAT Relay Bypass Switch Kit is a versatile and practical tool for diagnosing and testing relays in a variety of vehicles. Its compatibility with domestic GM models, BMW, Audi, and Chrysler, combined with its relay testing and fuel pump bypass functions, makes it a valuable asset for automotive technicians and DIY enthusiasts. The 6-pack provides a comprehensive solution, though users should be aware of potential learning curves and ensure that the kit meets their specific needs. For those working frequently with relays and electrical diagnostics, this kit offers convenience and functionality, provided the components are well-maintained and properly used. ... show more
