Hi Art
With your alarm on, either lights or both sound and lights and you shut down your engines, the OIL lights and or bell will light up or ring because there is no oil pressure. The alarm sys does not know why there is no oil pressure, just there is no pressure. If one of the oil lights does not light up on shutdown (alarm in the on position) you have a problem with the one that is not lit. The only way you can shut of the lights or bell with the engines off, is turning off the alarm sys. or restarting your engines. Your water lights will not light up when you shut down because you have not overheated your engines. The only time they come on is in an overheating situation. I hope I made it clear for you? Capt.

For Uni's oil pressure alarm info! Will post when repair completed. Capt Perry - Correct me if I misunderstood; the way I understand what you depict about Uni alarm system: Oil alarm SHOULD activate alarm sound and light when eng is shut down and then STOP activating when eng is started. I thought oil pressure and water temp alarms were to activate when engines were on and a problem occurred. I only mention the following because I now wonder if my Uni's alarm system is currently working correctly. My alarm area has one toggle that allows alarm activation to occur with light only and/or with both light and ringing bells at the same time (I keep it in position to activite both lights and bell ring). Alarm area's other toggle (an alarm activation switch) has three positions. Off, On and Test. When in Off position nothing occurs engines started or not. In On position all alarms are not activated when engines are started or stopped, unless a problem occurs while engines are running (except recently the port alarm light and ring is activating even with engines off). The Test position lights up all alarms and rings the bell whether engines are running or shut down. Do you feel the alarms are operating as designed. except the port oil alarm? Or; is it that only the port oil alarm has begun to act correctly? I did have an overheat alarm activate once 6 months ago; and for a good reason! Is saved my engine and my a%$! While piloting from bridge, port engine had developed a pressure leak in a hose of its fresh water closed loop system. No lasting engine problem occurred; alarm sounded loudly at 190 degree temperature on guage, and even with engines running at 2850RPM and heading into stiff breeze I heard the alarm bells on the bridge. TG! So I knew that at least one alarm was working correctly!

One sender is much larger than the other on it. The larger one on my boat is for the oil gauge and the small pancake looking one is for the alarm. If you are not sure which one, take the wire of the large sender and see if you still show oil pressure, if you do not than that sender is for the gauge. You can buy senders with different pressure ranges on them. The alarm sender can be what ever you want it to be. The oil gauge sender has to be match with the oil pressure gauge or you will get false readings The oil pressure alarm should sound and light up when you shut down the engine If it turns its self off when you restart the engine, than it is working correctly. Make sure you have good grounds (common problem), A poor ground will cause you problems Capt.

So yes, I would expect that yours is near the pressure sender. I don't know your engine(s), so it is possible that they are NOT together, but I'd look there first. Good luck and let us know what you learn.

Our Uni is a 1973 31' Sport Sedan: Been following your oil alarm posts. I have a port oil alarm that rings and flashes the alarm at incorrect time... my ring sounds and light flashes the port oil alarm seconds after the motor is shut down and oil pressure is at 0. I simply flick the alarm master switch to off and on; depending if motors are started or off. But, I wonder if the port alarm would work if oil pressure dropped while motor was running?? Can you tell me where to look for the sender switch in this case? I imagine it's on the engine right by the sender for oil pressure gauge - correct? I've not searched for it yet but plan to locate and replace it in near future. Any hints appreciated!

I have determined that mine is closed at low or no pressure. Therefore it is OPEN at pressure. I glanced at Summit but I don't see anything there, so I will stop in at my local auto parts store.
