AutoMeter Heavy-Duty Automated Electrical System Analyzers

AutoMeter heavy-duty automated electrical system analyzers work on most 6 V and 12 V batteries, including AGM, battery banks (up to 4 batteries), and 24 V systems. Due to their 400 amp true load system, they can apply a load through the tester for quick readings on the alternator, battery, starter, connections, and wiring. The testers feature Digital Pulse Load technology, allowing operators to quickly evaluate cranking power—as well as V-drop technology, which measures voltage drop associated with starter engagement. This product also connects to AutoMeter's truck/trailer adapters (available separately) to quickly assess all electrical issues. They run on their own 6 V SLA battery which recharges internally whenever the cables are hooked to a battery. Show Less
