I prefer to use a piece of wire - helps to eliminate the possibility of touching the "wrong" thing - the wire only needs to be 6-8" long- just about anything except speaker wire.. touch one end to the battery terminal and one to the starter terminal (I think it is the bottom left terminal) you'll likely get a quick spark and the starter will engage.. no need to hold it there - it'll either spin the starter or it won't.. if it does, it is likely the relay that is suspect - - replace it and try via the key/ignition switch again.
