25 hp four stroke carbeurated bigfoot won't shut off with key. With key off black/yellow is grounded all the way to the ECU. Does grounding shut this motor off or an absence of voltage to ECU

With key off black/yellow wire is grounded to ECU and open with switch on...yet engine will not shut off

Check to make sure that the black wire on the key switch is actually going to ground as well. This is where the black/yellow wire gets its ground siginal to kill the spark to the engine.
