Engines won’t shut off at the Helm with Kill Switches

Engines won’t shut off at the Helm with Kill Switches.
2004 290 BR engines start up normally with dash switches however will not shut down. Manually have to go turn the keys to shut down the engines. Any thoughts?

Welcome aboard Justin!

I don’t have a answer for your question but I am sure one of the engine gurus will answer shortly.

Just an FYI, most members use the “New posts” function that summarizes all forums new posts, so you only need to post your question in one forum.

Good luck!

Bad diode in the alternator back feeding the ignition possibly.
