I replaced the starter solenoid on my port 1989 200 Mariner. Now with both batteries fully charged neither engine turns over. My first thought was bad solenoids which it probably is. Howver why did they burn out so fast especially on the port engine. Here's the wierd part... Without the key in the ignition, I turn on the battery to port engine and engine starts to turn over. Like it's possessed. Must be a short..<br /><br /><br />Any ideas?<br /><br />Thanks folks
