Horn sounds when ignition on

[javajohn]

The battery died while my 1991 NSX was in storage. I charged the battery and when i connect it i hear a clicking sound from the CCU area and if i turn the ignition on the incab horn sounds. The car will start and run, the other horns don't sound, and the lights don't flash.
The car is in original condition with 20K miles.

Any ideas?

incab horn? Do you have an alarm?

Yes, I have an alarm. But the alarm activates all three horns, the lights and I believe will not let the engine start. I used my key in both doors to deactive the alarm but that didin't help.

Car was in storage - check for mice chews on wiring. Try disconnecting the battery and then reconnect it (positive terminal first).

Could be mice. I think it is a short somewhere because the battery should not have been completely drained in 6 weeks. I may look at the cable reel because my SRS light is on and the SRS fuse blows when I put a new one in. Will also try horn relay.

Problem turned out to be a blown amplifier. It made a very loud siren sound that I thought was one of the horns.
