8.12.13 Amps Sensor
The SV-EMS-220 utilizes an ammeter shunt to sense amps. Refer to the airplane or engine
manufacturer’s maintenance manuals for detailed location information.
If your aircraft did not originally come equipped with this sensor, refer to the
Equipment
Installation Record
document to see where the sensor is located on your airplane.
Removal:
To remove the Amp sensor, follow the removal instructions in the airplane or engine
manufacturer’s maintenance manuals, or complete the following steps:
1. Shut down airplane power.
2. Temporarily label wires connected to sensor to ensure correct orientation when
reconnecting wires.
3. Remove screws that secure large input wire cable terminals to sensor.
4. Remove screws that secure large output wire cable terminals to sensor.
5. Remove screws that secure small signal wire connected to input side of sensor.
6. Remove screws that secure small signal wire connected to output side of sensor.
7. Remove screws that secure sensor to airframe, and then remove sensor.
Installation:
To install the Amp sensor, follow the installation instructions in the airplane or engine
