Spike relay problems
 

What are the possible replacements for the The Spike H-Bridge Relay from Vex?
Our spike relay is making a clicking sound whenever it is turned on, therefore the compressor is not functioning at all.

Per R51, a the only legal power regulating device for the compressor is a Spike Relay. Therefore, you'd have to pick up another replacement Spike Relay from VEX, a local team, etc. to be legal for competition.

The Spike is a mechanical relay, so a click every time it changes state is normal. What colors are the LEDs on the Digital Side Car (DSC) and Spike?

Connect the Spike to a DSC RELAY port with a 3-wire PWM cable. Connect the black wire to the outside of the DSC (closest to the locking tab) and to the letter "B" at the Spike. The LED on the Spike should be amber if the DSC is not connected or is not trying to drive it. When you are commanding the DSC the corresponding LED should illuminate green. The Spike LED should also turn green. For more details, refer to the User Guide is at http://www.vexrobotics.com/vexpro/mo.../217-0220.html.

Pull the fuse out of the Spike, if you haven't replaced it with a 20A breaker. If the fuse is blown, replace it with a 20A Snap-Action breaker. (If the fuse isn't blown... replace it with a 20A Snap-Action breaker.)

Note that this is only for the compressor Spike.
