Boat has been sitting for a good 3 years. 400 hours on a 502. sucked gas out a month ago and put new gas and started running it good idle on the side yard twice a week for that last month. i checked alternator and it was showing low output. took it to get tested at a shop and they said the regulator connections were not connected. They connected and said it was good. i put it on boat and it sparks from the alternator bracket. fuel pump works when alternator is off alternator bracket. when i tighten bolts it sparks and fuel pump does not turn on. HELP!!! Im going to needles to tomorrow for the weekend and might not take the boat if i can't figure it out.
