12 Volt Motorcycle Battery & Alternator Tester

This motorcycle battery tester is a great little tool to keep in your glove box or tool chest to quickly learn basic battery and alternator information. The colored LED lights on this motorcycle battery tester display easy-to-interpret results instantly. The alternator results on the top of the tester indicate a GOOD or BAD alternator voltage output. When the voltage is too high, the illuminated BAD LED lights up. The battery test display on the bottom of the tester shows your 12-Volt battery’s state of charge as a percentage of output circuit voltage in 100%, 75%, 50% or 25% increments. The tip probes of our 12v battery tester are designed to work either remotely by inserting the test probes directly into the standard quick disconnect connection on your motorcycle without touching the battery posts directly or by touching the tips to the battery terminals directly. Touch the red fixed post probe to the positive battery terminal and the black coiled-cord removable probe to the negative battery terminal.
