  ammeter & PowerPost.JPG - Again, the LED display is much brighter in real life. As you can see, the ammeter uses the common negative on the PowerPost (left). Its positive cable routes through the switch (bottom center), which allows the meter to get power from incoming, outgoing, internal or external sources. The center switch position turns off the meter, but does not affect the flow of current through the system. I chose this ammeter because of its compact size and open loop current sensor (bottom right). Unlike a traditional shunt, exceeding its current capacity will not burn up the meter, etc.. It's rated for 75A, which is far more than the 25A max that the booster can pass through it.
