Re: Warning Light Stays On

On older boats the tan/blue alarm wire is connected to 1/low oil pressure switch 2/high water temp switch 3/drive oil reservoir.

the alarm will sound if any one of these switches closes and makes ground.

Thanks ,sounds to me like if the switch goes to ground the alarm goes on.So if i have all three wires are disconnected and the alarm still goes on ,one of these wires must be grounding somewhere! I'll do somemore looking.
