Since you have an automatic transmission, I hope the neutral position switch isn't the cause of all of your problems--just a thought in passing. This interlock would interfere with the main relay and ECM. I'm sure you placed your car in "Park."

I normally turn ignition ON, set DMM to DCV, and touch leads to test points on top of fuse. If I disconnect the battery, I set my DMM on audible ohms and check all under-hood and under-dash fuses in a couple on minutes.

OK, well I am at work and I know that for a fact I do not have any fuses in #24 (I love photographic memory). Also know that at the #24 spot there is a picture of a fan embezzeld on the fuse fan where this is located.

Does your Civic have air bags (SRS)?

I've meant to ask you has battery acid damaged your under-hood fuse box?

Anyhow, in my mind, we are back looking at a fuse, ignition switch, under-dash fuse box, or main relay harness issue. Do you agree?

I hope I did not "nuke" it (a term in the navy of the nuclear people for nuclear-power subs that work these spaces, they think so complexed that they never think of the simple things) and totally overlook this fuse. But how was I driving all this time without it :-/

I do not have a #24 fuse and I do have airbags...

TxGreaseMonkey · Sep 13, 2006, 03:03 PM

On my Civic, the fuse you need to check is just to the left of the SRS fuse. My under-dash fuse box cover refers to it as the ACG (S) fuse, part of the SRS Fuse Block. There's a yellow plastic cover, with an opening in it, over the SRS fuse (No. 25), next to it.

davin · Sep 13, 2006, 03:12 PM

I only have a 10a fuse with a yellow cover and to the left of that is no fuse

TxGreaseMonkey · Sep 13, 2006, 03:15 PM

Does the fuse box cover refer to a fuse as the ACG fuse? Should be 15 A.

davin · Sep 13, 2006, 03:18 PM

When I bought the car, there was no cover. The only reference I have of "location #24" is an embezzeld fan on that spot and I do have airbags

TxGreaseMonkey · Sep 13, 2006, 03:21 PM

So you are confident you didn't overlook any fuse? If you didn't, then it must be in the harness or ignition switch.

You definitely should read around 12.5 volts from Terminal 5 on the main relay connector, when the ignition is ON. That's the issue.

The fuse may also be labeled ALT.

davin · Sep 13, 2006, 03:23 PM

I checked all the fuses to see if they where broken, but I never checked to see if any where completely missing. I will buy a 15a fuse when I go home, put it in location 24 and see what happens

TxGreaseMonkey · Sep 13, 2006, 03:27 PM

There should be 4 spare fuses in the under-dash fuse box. Normally, the extras are at the end of each row of fuses. One at the end of each row on the left and one at the end of each row on the right.

davin · Sep 13, 2006, 03:29 PM

Just to make sure, location #24 is the second to last fuse from the top right... is this correct?

TxGreaseMonkey · Sep 13, 2006, 03:34 PM

Yes.

TxGreaseMonkey · Sep 13, 2006, 04:07 PM

This might help:

Scroll way down and you will see the under-dash fuse layout. Look for the ACG (S).

TxGreaseMonkey · Sep 13, 2006, 04:20 PM

You might find it useful to know that power for Terminal 5 comes from the IGN 1 position on the ignition switch.

VROOM VROOM!!

OK, so I just replaced a $700 15a fuse in location #24 and now I am thinking it was someone at work screwing with me because we have a back and forth game where we mess with peoples things. Well, what I am thinking is someone took my #24 fuse and completely forgot to tell me. I mean, how else would this fuse be completely missing.

I replaced the fuse and it started right up! I think I will start confronting people at work and see what the deal is. I have a pretty good idea as to who it might have been. Thank you for everything and I am not very happy with this person right now. This was crossing the line and payback is a *****.

I will do a write up and a trouble shooting guid for this unless you want to do it. Better yet, we both can do this if you want? Anyway, I have to head out to school with a car I can actually drive now :-D

Thank you for everything!!

Praise the Lord! I am elated for you. Davin, do you know we worked on this for 5 days? You aren't the only one who's torqued-off at whoever did this. My guess is that it's your "buddy," who owns the other Civic, because it takes detailed knowledge to know the significance of this key fuse. This was more than a prank. In my opinion, this could be an Article 15 (Mast, in the Navy) and possibly an Article 32 violation of the Uniform Code of Military Justice. Don't retaliate and go down that path. The individual should be required to reimburse you for your expenses. This affected your readiness, your education, and your wallet in a big way.

The positive is that you now know your Civic like very few other people. You also have a new distributor, ICM, coil, distributor cap, rotor, spark plugs, main relay, and a spare ECM and ignition switch. Your Civic just got a new lease on life. Now, we can move on and talk about fun maintenance items you can perform, without so much tension and feeling of impending doom.

Davin, go back and "baseline" your ECM, by taking a reference wire voltage check on your MAP sensor connector. Also, be sure to print a copy of the under-dash fuse/relay layout and keep it in your car.

Yes, I will definitally do that. I confronted te person about it and he is going to buy me lunch for 2 weeks. He feels bad because he went home and completely forgot to tell me. The following day he was afraid to tell me because I was really upset and immediatally threw money at it. When I knew it was a prank, I confronted him and just plain said that he owes me lunch for 2 weeks. He knew I knew it was him and he said OK. We are cool now, I learned a lot and I am just trying to be optimistic about this.

Thank you for everything 4sure. I learned a lot and now I know a lot about civics so if I ever have these problems I know what to do :-D
