Having a weird issue with my port ignition on my 2008 46' Ocean SuperSport with MTU Series 60. The ignition will not turn off with the rocker switch at the helm. I have tried disconnecting the rocker switch thinking it was faulty and that did not work. Had the local MTU service look for an issue and they couldn't find anything. I have recently replaced all the engine electronics, ERM, ERIM, MIM, and etc. The only way to shut off the ignition is to turn off the starboard side battery switch. Any ideas on what the issue is? The techs think its a wire somewhere. Any input would be great!! Thank you in advance!
