"I have a 1994 Johnson 115hp.
"I have a 1994 Johnson 115hp. With the key on, warning horn has rapid high/low oscillating sound. I disconnected the wires for the oil tank, and the sound was the same but not as loud. Disconnecting the temp sensors did nothing, but disconnecting wire harness to fuel pump stopped the sound. So, 2 things are making the same sound at the same time- oil tank and fuel pump. My manual doesn't say anything about a warning for the fuel pump, and my oil injection system is positively working perfectly as I can see and smell lots of oil in exhaust. Any Ideas on what's causing the warning, and how to fix it? Oh yeah, where is the best place to by a rectifier/regulator assembly? How much? Thanks for any help."
