 Description   

This issue was initially filed into JIRA by 'arnaud.lefur' at 02/Feb/16 9:02 AM as ICS-24.
This issue was assigned to 'Steve Hope'.

When the motors are powered on, it made pcm to fail to read gauge value from time to time, in a very cyclic way.

When we power off, everythings back to normal.

Several changes were made to the motor controller power feed in 2017-03, and noise is way down. Closing this.
