About this product

Overview

Product overview

• A handy device for checking the condition of your car battery and alternator charging voltage • Simply connect the tester to a suitable ground point and place the test probe on the positive terminal of the battery while the engine is switched off • LEDs light up to show the current state of the battery; from one - the battery is discharged to three - a good battery condition

With the engine running at about 2000 rpm, connect the test probe to the output of the alternator. Indicators now illuminate to show the state of the alternator. As with the battery condition, combinations of LEDs indicate whether the alternator voltage is low, normal or too high. Ideal for fast and simple diagnostics. Supplied with full operating instructions.

Does this mean the battery is good if all the lights come on with an auto-x5?

What is the maximum voltage this device can cope with? Does it show overvoltage e.g. > 14V
Asked by: Wayne
15V max - no it simply indicates whether the voltage level is high or low
