Questions about this product
- Will this tool work on any type of relay in my car or RV?
- It is designed specifically for standard 4-pin and 5-pin 12V automotive relays. It will not work with non-standard relay pin layouts or systems that do not run on a 12V DC battery.
- How do I connect the tester and run a diagnostic test?
- First, attach the battery clamps directly to your vehicle's 12V battery. Next, plug your 4-pin or 5-pin relay into the matching socket on the tester. Press the push-button to start the quick 2-to-3-second test cycle.
- Can I use this tester on a dead battery or a heavy-duty 24V system?
- No, this tester requires an input voltage range between 11V and 15V DC to function. It will not operate on 24V commercial trucks or if your 12V battery charge drops below 11V.
