Will not turn off

90 Hp Johnson will not turn off with key.  I replaced the ignition switch wit an OEM and still the same problem.  Also found that the bilge pump and bait wells would not work.  I checked the dash and it they are getting power.  I suspect a ground issue but unsure how to proceed.  The engine runs well, just will not turn off.  All gauges and lights work.

To answer my own post, I hound the black and yellow ground wire at the engine had broken. I spliced the wire and sealed and solved the problem. Found that switch requires connecting two grounds to cut the motor off.
