testing warning horn 1997 115

[boston2]

hello guys,i just bought this boat and am going over maintence items before using it.im testing my warning system on my 1997 evinrude 115 90 degree cross flow with vro .when i turn the key on and test the system the led lights work and horn sounds for a moment[self test seems to work].when i ground out the temp sensor wires i can get the led light to go on but no horn .i also tryed this with the oil tank sending unit it also lights the led but no horn.i hooked up volt meter to alarm wires and get nothing even with the key left on for 60 seconds.what am i missing as i cant find this senerio in my workshop manual.thanks scott

Just a guess ,but I'm thinking your audible alarm isn't connected from the rigger.My bros. boat was rigged the same way when new .Just the lights.IMO,those lights are worthhless.Particularly ,when running full out.I don't like to watch my console that frequently.

He didn't yet.And I never had the opportunity to inspect the hookup.Just grounded out his temp sensors one day to test for him while he was flushing his motor. Just the light came on.You'll need to confirm that the alarm in your controls ,not just the lights ,is wired in circuit from the alarm module .May be the alarm horn itself is defective.

Engine needs to be running to test horn, by grounding sensor wire.

You sure about that Clanton.My 96' model overheat sensor will audible test by grounding with just the key in the "on" position.

Clanton i have not tryed it with the motor running ,but the key is in the same position ,does it have something to do with the charging system?That is the only diffrence i can see.

OB.. the alarm horn sounds when self testing so it is wired in properly ,just doesnt sound to warn when sensors grounded..

No Im not sure of anything lately, but only takes 45 seconds to start engine and test. It would depend on which tach you are using. Plain tach, alarm should work engine off, System Check tach, the one with lights, engine needs to be running. The self test only tests the horn, does test sensor or wire to sensor. I will look in manual today.
