Starter went out so i went and got a new one only problem is the new one only has the one small post on it, the old one had 2 small ones, i was told by the boat shop to hook the two to the same one but when i do the boat will only run as long as the key is in the start position. as soon as i let it off of the start position it dies. if i hook the one wire to a hot from the battery it will run. now i have no power except to the lift for the drive, checked all the fuses i can find and all checkout (two 50 amps fuses and blade type under the dash). didnt think a starter could be so much trouble. Why would the new starter only have the one small post? motor is chev 350 thanks in advance.
