Fuse for connection near fuse box
I really blew it-a fuse that is. I just connected my air horns to the terminal next to the fuse box (near the jump start terminal). After a few 'toots' it stopped working. I checked with a test light and there is no power there anymore. There is a factory harness connected to it, and I was wondering what it powers (that is also not working anymore). Also, where is the fuse for that terminal? And can I up it to cover the horn, or should I get power from the jump start terminal?

Help
Any ideas, please. I am off tomorrow and may need to go to my Chevy dealer if it takes a special fuse or circuit breaker. Plus, I don't know if I am doing any damage driving the car with the mystery circuit not working (whatever is connected to that positive post).

It's very strange. This morning, the alarm I have hooked up to the power post is working again (but the airhorns connected to the same post aren't). The factory harness that is connected there seems to go into the firewall. (I can't really check because it is raining outside.)
|
I believe that the harness is for the power steering pump. I am now going to get wet and check for the fuse.

Lee; there is a BIG 50-amp fuse located at the battery terminals under the rear storage compartment:
http://www.socalhhr.citymax.com/i/Hi...ain_Fusesm.jpg You might check that one first. If it's blown, you might need to go to the dealer to get one. BTW- You should be running a relay for your air horns, never hook them up direct. Hope it helps, |
It is the strangest thing. At first when I checked the power to the post, it was dead. The next day, it was back again and my siren works again. I relocated the horn (of course I am using a relay and 20 amp fuse) to the terminal for jump starting the car, and it appears that the compressor is not working. It is odd, since the horn is brand new. It worked for the first 10 minutes then crapped out. To further check things, I just connected it directly to the car (with a fuse) bypassing the relay and switch, and the compressor didn't make a sound (I did get a spark).

You must have triggered a circuit breaker - and now it has reset.
Perhaps they have a breaker on the whole underhood box. That's the only explanation I can come up with?? |
That's what I figured. Now I just have to get my air compressor replaced!

This is really killing me. This morning, my siren hooked up to the PS terminal worked. This afternoon, nada. Tonight I exchanged my airhorn compressor then decided to test it in front of the store. Nothing. I checked with a test light, and got no power to the PS terminal, the jump start terminal, or the open connections in the fuse box. The other day, these terminals all showed power. I checked the fuse by the battery, and it was good (when I pulled it, interior lights, door locks, etc wouldnt work). So what could be wrong?
If it is a circuit breaker, it may be fine in the morning. If not??? |
