Help with Loooong beeeeeep alarm

[Kiwi8401]

Hi, I need help on info about a looooong beeeeeeep sound on my boat. I bought a boat 2 weeks ago, tried the boat at the lake, check compressions and everything on the boat before making the purchase. Everything turned out ok, traveled 8 hours home after from where i bought it, then took the boat the following weekend to the lake and as soon a as ai turned the key switch, a looooong staedy beeeeep sound alarm went off and would not shut.
I was told it could be the temperature alarm, (VRO pump has been disconected,)but i had not been more that 30 sec at the lake. What could this be?
I have also researched online for possible short on my motor.... ( 1989 Evinrude 175XP)
I would really appreciate any feedback on this.
Thanks,

Nester,

Re: Help with Loooong beeeeeep alarm

If the warning horn starts to beeeeeeeep as soon as the key is turned on (engine not running), remove the TAN wire for the warning horn temporarily. If the horn continues to beeeeeeeeeeeeep, the horn is faulty.

If, on the other hand, the horn stops beeping when you remove that TAN wire, one of the sensors is shorting out at the engine OR that TAN wire is shorted out somewhere. If this is the case, disconnect the sensors at the engine one at a time until the beeping stops, at which time you've found the faulty sensor.

NOTE: Do not leave the TAN wire on that horn disconnected!

The TAN wire must be connected to the slide on terminal closest to the build in black ground wire, with the purple wire connected to the slide on terminal furthermost away. If reversed, weird things will happen!

NOTE: I retired around 1991/92. Possibly some of the later V4 engines and others may also incorporate a fuel vacuum switch that would enable a fuel restriction warning to sound as mentioned below, an unknown factor to myself.

1 - A steady constant beep = Overheating - The V/6 engines, possibly some others, have a fuel restriction warning which is also a steady constant beep.

2 - A beep every 20 or 40 seconds = oil level has dropped to 1/4 tank. (Late model engine = Every 40 seconds)

3 - A beep every other second = VRO failure, air leak in oil line, oil restriction, (anything that would result in a lack of oil being supplied to the engine).

NOTE - If the warning horn is the black plastic (overpriced) three wire type horn, the warning horn should beep once when the ignition key is turned to the ON position. If it does not, it is either faulty or someone has disconnected it (a stupid move!). At any rate, if it does not beep which indicates that the horn is non functional, find out why and do not run the engine until the problem is corrected.

Hi again Joe,

I am happy to advise you the looong beeeeeep is gone! connected the muffs to start my motor.

1. inserted key, turned (motor off), beeeeeeeep went off.....
2.-I unplugged the horn as you told me, (horn shut down).
3.- removed my key.
4.- pumped the fuel primer a couple of times
5.- connected the horn again
6.- inserted the key, pushed choke, turned key, started motor & BINGO!! gone!

I hope this takes care of that beeeeep for good,
could this be that the horn alarm was in a way reset it??

On another note, my Ranger boat has 2 fuel tanks and a switch shut off valve, i was told by someone to also everytime i swith tanks or shut off the swivel valve, for me to press the fuel primer couple of time to make fues there is enough fuel passing thru...... that this could be a reason why the alarm could go off other than overheating, low oil, etc.....

BIG, BIG thhanks for replying and helping me out with this.

Re: Help with Loooong beeeeeep alarm

I do wish you luck with the horn problem BUT the results of that test would indicate a intermitent sensor problem or a weird conductance type short in that TAN wire.

However, hopefully, you'll be one of the lucky ones. Let us know if that problem occurs again.
