Crank: the engine turns over when you try to start it, usually making a repeated "ruh-ruh-ruh" sound. No-crank: the engine does not turn over; you might hear a click or silence. Battery terminals: the two cable connections marked + and −. Voltage: an electrical measurement, not by itself proof that a battery is good or bad.
Safety first: stop if you notice fuel leaks, smoke, overheating, unusual mechanical noise, or exposed high-voltage components. Never touch moving parts while trying to start an engine.
