Associated Equipment 6/12/24V Carbon Pile Load Tester, with a 600-amp load, combines the versatility of a carbon pile load with easy-to-read, digital meters to give a quick and precise determination of problems with the battery and/or charging systems. This variable-load tester features unique, curved discs to help prevent hot spots for a smoother operation and longer life, and this unit is spring-loaded to shut off automatically. Both the voltmeter (0-19.99V DC) and ammeter (0-600A) feature digital LCD displays, and the heavy-duty, 500-amp safety clamps with "Flexi-Spring" cable guards provide added value. This made-in-the-USA product has a limited manufacturer warranty of 1 year (90 days on the carbon pile assembly) and also comes with 5.5' DC leads (4 AWG) with a buried tracer lead-in cable to prevent damage, measuring 11" H x 19" W x 14" D overall.
