2004 Yamaha 60TLRC Oil level sensor wiring... Boat only has buzzer on 704 control console, no digital tach.
I tested and determined that the oil level float sensor was bad, previous owner solved the problem by unhooking the pink ground wire (circle B)
once I found it and hooked the bullet connector back up the low oil level alarm horn just stayed on when key in on position.
So I replaced the oil level sensor with a new OEM part, tested new float b4 installing on ohm meter, all good.
when i hooked everything back up and turn key on, buzzer stays on... So disconnect plug circled in A from new float and alarm goes off, plug it back up alarm back on. unplugged Circle A plug from float sensor leaving pink wire hooked up (Circle B) and (black wire grounded to block) and drained the oil tank, as the oil level gets nearly empty Low Oil Alarm sounds as it should. I refilled the oil tank turned the key off, then back on and alarm went off.
My question is this... Since I don't have the Multifunction tach, with all the bells and whistles is it necessary that the connector in circle A be plugged up ? as long as the Alarm sounds when the tank is near empty my system is working as it should the way it set up now correct ? I also tested the temperature sensor in boiling water to verify that it was functioning as design to. when submerged in boiling water it sounds the alarm like it should. I am just perplexed as to why having that (A Connector) plugged up sets off the alarm, there is a Green/Red wiring coming out of it and another color wire that I can't remember.
