Wiring Digital Voltmeter Ammeter Without Shunt
I have this: http://www.ebay.com/itm/271210262267?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
. They say is can it be used up to 10 amps without a shunt, but I can't find wiring diagram. I am trying to wire into 50 watt led light. I know the small red and black go to power source. I am not sure how to connect 3 thick wires( red, black, yellow) without a shunt. I am only trying to meter 1.5 amp circuit.
Here's what I am trying to wire. Thank you
