Not sure what caused this issue, unit started a week ago and when I went to check the oil the negative battery conection broke. I replaced the connection and battery as the old one was, well old, and today when I went to start I had a few sparks at the Starter Relay or Solenoid as per my diagram. I get no attempt just the sparks. And then after the second attempt to start there was nothing at all. Checked battery voltage and its fine, I have power to the battery side of the solenoid. Am I safe to assume its the solenoid that is the issue?
