I have a 1992 225hp Johnson. It will not turn over now when I turn the key. I can however start it easily from the selenoid and it runs fine, and kills when I turn off the key. When the key is turned on, I have no juice to either of the two small connections of the selenoid. Is this telling me that my ignition switch is bad, or the selenoid? If it is the switch, can that alone be changed, or do I have to replace the entire wire harness? Thanks in advance for any help.
