I/O won't shut off with key or lanyard

[Buck Snort 2]

A person I work with has an I/O Glastron 3.0 Volvo Penta boat. She was having problems starting it so a new battery was added. Upon further review it was found that the Lanyard wasn't completely engaged. Now with the Lanyard in place the motor will not shut off using the key or removing the lanyard. She needed to remove the coil wire to stop the motor.

She also mentioned that the ground wire to the battery was just resting on the battery terminal and not tightened down.

She doesn't have a User account here so I am posting this for her.

Any help on wha tthe problem might be would be greatly appreciated and thanks in advance.

First of all you should convince her to join FM, she will be happy about it, it's not just "fishing talk".

Then I would take it to a shop and have it checked, it's difficult to pinpoint an electrical problem, especially when reported by a 3rd person, and without more information.

Somebody will pitch in and give you some hints, but I would suggest taking it to the shop, it's not safe to run a boat that cannot be shut off.

She has contacted her dealer and they suggested changing out the ignition switch @ $35 plus the time to personally install it.

I'm guessing it to have an electronic ignition so would a ground wire bouncing around on a battery raise enough problems to cause a failure in the electronic ignition?

If the ignition switch was defective wouldn't the Lanyard still be able to kill the motor?

I think that rather than contacting a dealer, bring it to them, have them diagnose and repair the problem. Calling and asking questions of dealers rarely results in the correct transfer of info in either direction. Something is providing power to the coil positive circuit, whether it is in the switch or a wire shorted to power, this would also explain the dead battery. If questions need to be asked for a situation like this, then the repair is over the owners head, not a bad thing, we all can learn by the hands on approach. This is not a good place to start learning about electrical systems, this could result in a gravely dangerous situation and should be addressed by a qualified shop right away.

I have passed on the information.
