If both of them wires are connected to a relay I wouldn't bet on it.
Relays are electric switches that take a small current and control a larger current such as Fan>Fuel Pump> or starter.
One big wire Red with the blue tracer comes from the battery positive terminal it should be hot all the time.
The other big wire goes to a load like fan pump starter. To close this switch and make a path we need a control circuit in the relay.
One of the small wires goes to the ignition switch and turn power on and off to the relay control circuit. The other small wire usually goes to the computer where a device called a driver is turned on by the computer when it wants something to happen. This driver completes the path to ground and causes a small electro magnet in the relay to energize and pull the larger switch into contact and complete the circuit to the load that is desired to turn on.
In the case of the starter the control circuit is connected to a small switch in the handle bar to complete the ground and start the motor with the help of the relay to apply a larger current to yet another larger relay the starter relay. WEW!!!!
