Author Topic: Keying 2-Way Radio causes EDC Controller to fault (Bit 7)????  (Read 5589 times)

We are driving our trucks with a 90R130 Pump - controlling that with a Sure Grip Joystick (JM Base).  When I key the mike on the two way radio the truck slows down and when i let go of the mike it sometimes stops the whole truck.  My values going into the EDC function block from the joystick never change.  Just the fault shows bit 7 - "Current flow between Out_A and Out_B. Possible cause is loss of a common ground connection."  I have checked every connection, changed radios, added cab grounds, ran the EDC Controller ground right to battery ground, nothing helped my issue... 

Anyone have some input/suggestions??
