I recently purchased a 28' Catalina that had a missing starter solenoid. Now that I have installed a new solenoid (and replaced a broken fuse on one of the solenoid wires), the starter engages when I turn on the Main battery switch on the electric panel. This happens without a key in the ignition or the stater button pressed? As you can probley tell from this message, I am a new to boating. Any help would be greatly appreciated.Thanks
