System doesn't work proplerly

[ronlv]

Hello me and my team are having some problems with what we think is the electrical system.
When we deploy the code to the crio and enable it the robot drives only backwards (one joystick is working out of 2), when we run it forward it runs for a second and stops and all with delay like it gets pulses.
if it helps the "bat" and "5v" lights on the sicecar are flashing and buzzing. the jaguars lights are not stable (sometimes green and sometimes red)
the led light isn't flashing too.
Please help us if we can we are hopeless..
Thank you all.
