Yes, but those won't read in low enuff graduation. A motor going bad will still run but if one reads 12 amps vs. 3 amps you know you has better replace it or face the down time later. Small motors typically run 3-4 amps. Also remember as the voltage goes down the amps go up and vice versa. lamps pull 1-3 amps at 12.8V. Clutches pull 3 to 4 amps @- sep and header and AC. Just random stuff FYI.
