Question 1: Will this work on my motorcycle or truck battery?
Answer 1: Yes, this tester is designed for use on any standard 12V lead-acid battery, which includes those found in most cars, motorcycles, RVs, and light trucks. It is not suitable for 6V or 24V systems.

Question 2: How do I test the alternator?
Answer 2: To check the alternator, start the vehicle's engine and bring it to 2000 RPM. Connect the tester clamps to the battery terminals. The corresponding LED will light up to indicate if the charging system is working correctly (Good) or if there's a fault.

Question 3: What do the different LED lights for the battery check mean?
Answer 3: The lights give you a quick, visual indication of the battery's charge level. Green indicates the battery is fully charged, yellow means it has a medium charge, and red signals that the battery is low and needs charging.
