honda civic del sol, dx370 siren failure

So I installed my alarm and had a question with the siren. I had the 'connect to siren' wire connected to an oogha horn. Just to see if it worked (yeah I got excited and didnt wait for the siren). Anyways, I went to hit 'lock' on the remote to arm the system and the horn gave a little noise. But after that....nothing. I don't know if by using the oogha I fried the siren part of the brain or what. The parking lights flash but the horn (and siren) don't work anymore Do i need a relay/should I have installed a relay? The horn isnt bad because I tested it on a 12v circuit and it still works. thanks for helping the new guy lol P.S. I've disconnected the alarm, made sure it wasn't in valet mode, etc. It doesn't work when using the panic feature either.

Connect a DMM to the siren output wire and see if you are getting 12v when it should be going off. You may need to actually set the alarm off to get a good test.Kenny

The alarm is either putting out 3 amps or 100 milliamps depending on the output you used. That horn draws 10-15 amps. Leading on from the previous post, I'm guessing you've fried the siren output.

That's OK then X 3, Kenny was being polite. Someone should explain pre-testing and using a relay to our poster.

Yes, I 100% agree that its probably a dead output. Back in the day I had one of those ooga horns in my truck and I remember it drew a lot of power to run it. So more than likely it killed the output. However, I am still being optimistic in that maybe, by some slim chance, it is still good. Kenny

You ever seen a chip blow? It's FAST!

Yeah this is what I get for not going with my gut feeling haha. I have an optional output for a horn honk. Better make sure I connect it to my horn rest eh? Haha

Relay*

You can use that to trigger the ooga but ONLY through a relay. It may sound a little odd since it will only send a pulse down that wire, but it will at least give some sort of audible warning.Kenny
