I have a Catalina 400 and have been experiencing some intermittent starting problems. Starts first go maybe 50% of the time. When starting key is turned, you can hear the solenoid engage (click) but the starter does not engage the flywheel or turn it. Battery is good. Changed the solenoid on the starter motor so it is good. I'm wondering if it is a wire or connection issue coming from the starter battery? The problem occurs when the battery switch is turned to either Battery 1 (starting battery) or both. Any ideas?
