Default Re: SRP51/SRP52 problem

How are you measuring the current?

You have to either interrupt the circuit so the current bring measured flows through the meter, or measure the voltage across a suitable resistor and calculate the current using Ohm's Law. Connecting a meter on a current range across a resistor is not going to work, and could cause damage.
