Re: 00 150 Johnson wont shut off
BC..... The kill circuit for the ignition (powerpack) is as follows:<br /><br />Black wire from ground to "M" terminal on ignition switch. Black/Yellow wire from other "M" terminal on ignition switch to powerpack. Black wire from powerpack to ground.<br /><br />When the ignition switch is in the off position, the two "M" terminals are connected internally within the ignition switch, shorting out the powerpack and killing the ignition circuit.<br /><br />If the engine will not shut off when the ignition key is in the off position, it is due to one of three causes which are:<br /><br />1 - The circuit between the two "M" terminals within the ignition switch is faulty (unlikely).<br /><br />2 - There is a break somewhere in that Black/Yellow wire.<br /><br />3 - The kill circuit within the powerpack has failed.<br /><br />Usually the problem is the Black/Yellow wire.
