I bought a Netro Spark to replace an existing controller (a Raspberry pi based Open Sprinkler system) which exploded probably due to a shorted solenoid.

I read that the Spark can detect solenoids that are drawing too much current; is it safe to connect the Spark to shorted solenoids without worrying about damage to the controller?

Should I test all the solenoids with an amp meter first just to make sure?
