Please note that the PICTURE UPLOAD function is not working. The iBoats Forum Moderators are working with the system administration folks at the parent company to get the issue resolved. This happened about a year ago and here we are again. In the meantime you can post photos as links to a picture hosting site of your choice. We are sorry about the inconvenience and will advise when the issue is resolved. Thank you for your patience.
Put a test light or voltmeter on the ignition terminal on the solenoid. Turn the key to START. No voltage says the main harness or key switch is the issue. If you read 12V the key switch is good and the solenoid is bad. Disconnect the main harness plug and check for corrosion. Clean the terminals and reconnect. Now try it.
