12V Battery & Alternator Tester
PulseTech’s Quick Battery and Alternator Tester is a fast, simple and safe tool for getting a quick overview of your vehicle charging system and battery condition. The colored LED displays give easy-to-interpret results instantly.
On the top display, you’ll see the results for your alternator output. When the voltage is too high, the illuminated BAD LED lights up. The bottom display shows the 12-Volt battery’s state of charge as a percentage of output circuit voltage: 100%, 75%, 50% or 25%.
The tip probes are designed to work either remotely by inserting the test probes directly into a standard quick disconnect connection, 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.
