Relay issues

[scruffmcgruff]

so I've got some 3wire 5v arduino relays that im trying to wire to boost the power sent to 2 servos, my professor suggested it. It seems like no matter how I wire it it doesn't work, any suggestions?

Show us a good schematic of your circuit.
Show us a good image of your 'actual' wiring. 
Give links to components.

What are you actually trying to do with the relays. What are the relays switching? No relay is going to boost power to anything on its own.

What's a 3-wire relay?  Relays have a minimum of 4 wires.

Connecting things at random without knowing what you are doing is likely to damage components.

Ya know , I've been wondering the same thing since 2013 when I first discovered arduinos.
