Spike relays not working

[Broncobot_kae22]

We have 3 brand new spikes and still nothing. We are not even getting 5v coming out of the roborio

What color is the power LED on the roboRIO? If it's red, you most likely have something shorting the 5 volt power bus. Check for debris around the roboRIO's connectors. Use a very bright light to search for something like a tiny strand of wire, or a layer of aluminum dust, that could be a problem. It would be contacting the center pin on any of the DIO, PWM, or Analog ports. It could be anywhere.

If the power LED is green, focus on the code.

the power light is green
the status light no light
the radio light no light
the comm light is green
the mode light is green
the rsl light is orange

Thank you for the detailed description. It might have given the explanation.


Power steady green means there's nothing wrong with the power. When you said you're not "getting 5v coming out of the roborio", where were you measuring?

Status off means the roboRIO has completed its selftest without errors.

Radio off means there's no USB radio. That's normal.

Comm steady green means the Driver Station is properly connected.

Mode steady green is the big clue -- it means the robot is enabled in Autonomous mode. Switch it to Teleoperated and see whether things start working as you expect.

RSL steady orange means the robot is disabled. That's not compatible with mode being green. Are you sure it's not blinking?

we are measuring the relay ports on the roborio for the foward and reverse pins. what could be wrong with why we are not gettinga green status light but yet it drives.

The Status LED can never be green. It is a yellow LED that only lights to indicate a problem.

Read the roboRIO User Manual to see what the LEDs mean.

I assume that "it drives" means your Spike is behaving the way you expect now. If that's not the case, we'll start over in diagnosing what might be wrong.
