PicoScope 7 Automotive
Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.
Perhaps a DMM set to AMPS would support that current flow, however, when removed the coils could not fire and the engine would have to die.I don't believe that the measurement instrument, scope or DMM, could be the ground path for the coils... No way...
Yes, Right !!! Not enough to light up a Small LED ??In 12 volt systems with the Picoscope we are talking about 12 micro Amps or 0.012 mili Amps of current right!?
And this is an area where Volt Drop is not the technique, a simple continuity, or load test will suffice.That said, that very low current in low current circuits can affect the signal voltage. Usually it is only enough to affects bias voltage type of signals
