I have a 1993 Sea Cat with twin 115 mercs. I dont have port tach or fuel reading when the port ignition is turned on. I removed the GRAY wire from the tach and fuel gage and the voltage reads NEGATIVE 10.5 volts. When the key is off it reads around .1 volts. I have a merc manual with diagrams but am not much with trouble shooting. Anyone aware of any comon problems?
The starbord engine works fine BUT the buzzer doesnt work when the key is turned on. I can tell you this the buzzer didnt work before I temporarilly removed the engine to rebuild the transom and I put a different engine back on this side. Any suggestions with this problem?
