VOLT/AMP SELECTOR
AMMETER
The AMMETER indicates the measured amount of amperes being drawn by the battery. When you first start charging a battery, the reading will be high, with the needle near 40 at the 40 AMP CHARGE rate. As the battery charges, the needle will fall to about 15 to 20 amps, indicating a charged battery.
At the 2 AMP CHARGE rate, you will notice very little needle movement.
When cranking the engine while using the ENGINE START feature, the needle will swing into the Start (red) area of the scale.
