1979 115hp Evinrude. The previous owner had disconnected the temp horn at the controls...noticed this when installing a new console. Hooked it up and got the following:
Started motor and the horn buzzes immediately and stays on. Killed motor and put key in on position and grounded wires leading to temp sensors...and got sparks. Both wires leading to the temp sensors are getting 12v with the key in the on position.
So 2 strange issues...
1. I am getting 12v to the temp sensor wires.
2. Horn sounding only when engine is running, but not when key is in on position.
Any ideas?
