Welcome to the forum!
1) is it a stock start relay?
2) there is no 'relay ground' on this quad
3) have you downloaded the service manual? It's free in a sticky in the 660 Maintenance section - Last page is the simple wiring diagram - check your wiring against it. Each wire has a unique insulation and color stripe color - determine what's what from these colors, NOT any color on a connector.
As to your other nearly identical post: I suggest you use (Edit - Delete - Delete Message - Delete This Message) to eliminate it.
