Automotive Relay Tester 12V Auto Relay Diagnostic Tool Small Handheld DIY Car Relay Tester with Battery Clips

My husband is a mechanic and needed this for diagnostic testing. It works great! It’s fast, you just plug in the resistor and tells you if it’s working or not. No ordering a new resistor and hoping it works. Eliminating unnecessary time and money.

Love this product - I tested several different 4 pin and 5 pin relays and saved myself a bunch of money.Highly recommend grabbing one of these

This product was exactly as advertised. Works great and very helpful. I highly recommend this product.
