A friend gave me a 1996 Seadoo XP and it does not start. I changed the battery, put in the key and nothing. I took a test light and found there is power coming out of the battery and going into the black box in the back of the ski. There is power going into one side of the starter relay, but no power coming out the other side, any ideas? I thought either the key went bad, or the relay went bad...
