If the a/c continues to cycle frequently you probably need to add Freon. Low Freon will cause that issue.
If the system is turned off (O position on the heat/ac control), nothing should be on.
As I recall, the ac compressor will cycle when you select the defrost setting to help control the humidity.
IMO, relay is not your issue.
Also, as soon as you turn the system from the O setting, the fan speed you have selected will come on.
