98 Accord 4cyl

Here is the problem:

1)I changed the battery (the procedure was correct, did not reverse terminals and there shouldn't be damage.)

2) Everything else works. but I noticed brake lights were out, fuse was burnt. changed the fuse in engine bay. Brake lights work

3) pressed horn, horn muffled for 1/2 second and went out. Cruise control stopped working, Brake Lights out again

4) Checked all plugs and horn relay. all connections are fine.
*Noticed that the STOP(Brake) fuse which I just changed is burnt again.
*Also tested that No Power is going to the horn relay terminal.

So, the problem occurs when I use the horn. It blows the fuse. using the brake lights only will not burn the fuse.

What's going on?? It appears those 3 things are related to that single 20A fuse under the hood, so i assume its the same fuse.

- Is the terminal supplying power to the 20A STOP light fuse overloaded? by what?
- Do i have a bad connection at the horn that keeps blowing that fuse?????

 

You've got a short circuit.

 

sounds like your horn is shorting out . unplug the horns replace the fuse push the horn button if the fuse doesn't blow you know what your problem is.

 

yes, im pretty sure there is something wrong with the horn circuit. but where? i tried and it is not the power supply connectors to the horn. where else can it short?

 

bump for more info :?:

 

If the horn uses a coil then I'd say the winding is shorted. A short in a coil will result in less resistance and more current flow, blowing the fuse. I don't even know what type of horn these use, though.

 

you are right. one of the horn's is creating a short. i took the bad one off and it works. just ordered a replacement from honda! thanks!

 

Sweet.
