1985 Johnson 140 alarm

[socalgsx]

I did some research and tried to find out why my alarm is constantly on. I can't find anything that sounds like my problem.

So here it it... I started the motor it was running then I needed to switch batteries so I did. then the alarm starts sounding constsntly. turned the motor off went to restart it and the alarm is still on all of the time. I tried the remove of the tan wire which I think is the wire that goes through the back of the horn thing not a pos or neg terminal? Is that right. if so when I do that the alarm is still on all of the time. does this mean that the horn is bad?
I just want to find out if thats it before I go and buy one. Also the store was closed so I couldn't get one anyway.

The main thing is that when I turn the key on the alarm is on the whole time the key is turned on. thank you for the help.

With the horn sounding...... If you remove the TAN wire from the horn and it continues to sound, the horn is faulty.

Joe thats the crappy part. The dash was rewired and there is no tan wire under the dash.
Thats the reason that I was asking about if the tan wire is the one that goes into the alarm box and its not either of the pos or neg terminal wires that plugs into the alarm module. If that is suppose to be the tan wire then yes with that disconnected it does still alarm.

Assuming that you have a three (3) wire horn..... a built in black ground wire and two plug on terminals.

The TAN wire should be connected to the horn terminal closest to that black ground wire.

The 12 volt power source should be connected to the remaining horn terminal. Disconnect the wire and check it with your volt meter, with the key ON, to be sure.

That little test will identify which wire is which.

If the wire were connected backwards, the horn will do weird things.

Okay I took out the alarm after pulling all of the tan wires at the engine with no change.

I hook up the ground to neg and I hooked up the pos to the battery and the alarm just goes off. To me that says alarm horn module thing is bad, is that correct?

Not really sure of what you're telling me.

It would have been better if you left the engine wiring as is and went by my last reply to figure out which wire was which at the horn.

If you're saying that you're simply connecting that internal black wire to the battery negative terminal.... and the positive battery lead to the horn terminal furthermost away from that ground wire (as below) and the horn sounds.... then yes, I'd say the horn is defective.

O Internal black wire (Connected to - battery terminal)

O Tan push on terminal (connected to nothing)

O 12 Volt push on terminal (Connected to + battery terminal)

If horn sounds when connected as above, the horn is faulty.

Yes I figured out which one was from the engine and which one was power it was hooked up right. That was when I disconnected the tans at the engine one at a time and there was no change that was when I just disconnected the alarm and hooked it up to the battery and it just was sounding.
I found out from some other research that apparently the Merc alarms are better??? I don't know about that, Do you have any experience with the Merc ones, is one better than the other.
I really appreciate all of your help on this you are awesome!!

The Johnson SELF TEST logic is buildt into the horn, Merc is not the same.
