I am very green at motor repair and having a problem, help appreciated! My motor won't start or even try to turn over (it's a 2008 4 stroke). I have tried multiple batteries that are fully charged. When I first hook up to a battery it will allow the tilt to work and when turning the key halfway it will beep and there will be a small spark at the negative terminal connection. Then the tilt will not work nor will it make the warning beep when turning the key to start ignition.

thanks in advance so I can get back on the water!
