Just finished my 120 install (love it!) and replaced eight panel engine instruments. Everything working well (have not calibrated fuel tanks yet - tomorrow's project) except the ammeter readout. I am using the GRT CS-01 Hall Effect sensor on the cable coming from the alternator. The EMS reading increases/decreases with aircraft load, but the reading continually fluctuates, rapidly, any where from 5-10 amps, or more. I have used a clamp-on DC ammeter on the line at the same time and it has a steady reading on it.
