i think it below the under hood fuse relay box.

and what should i do with it??

there is a procedure on how to test the eld. if it bad you have to replace it. you have to remove the fuse box to gain access to the eld.
you will need a service manual, and multimeter.

a multi meter or a ohms meter?

2lua

either one will measure the dc voltage will work. do you have a service manual. i can't copy the page, i tried to do it but no luck sorry. may be some one here can will post the eld test procedure pages from the helm service manual for you.

i threw that code and i replaced a relay and it was cool

Turbocoupe97

what relay?

An ohm meter will not measure voltage, it measures resistance. You need a volt meter to measure voltage which any multimeter can do.

os its located under teh fuse box?

I was throwing this code # 20 and it was all in the distributor I had wired a obd1 distributor into an 91 Si CRX with b16a. and it needed an obd0 now it runs fine with no codes. have you tryed to wire anything in the distributor or anything?

bump, more info needed on this topic.... i too, am getting the code.

the ELD is actually the fuse box it's self, well IMO.

Find a helm and follow the directions for testing the ELD

here's the deal, cause i've been going nuts on a charging prob myself. the ELD is basically just an ammeter (it measures the car's current use while running). BUT, fc 20 can also set if A) you have low charging voltage / weak alternator, or B) if you have idle-speed (low idle) probs. But, basically, the black/yellow wire should
read battery voltage w/ key on (engine running or not); green/red is supplied 5 volts by the ECU, and the 3rd is a ground. How it works is, as loads (lights, etc) are turned on (engine running, of course), the voltage on the green/red wire will drop. i.e. engine hot, nothing switched on, it should read 3v or so; turn the blower motor on High, 1.6-2.0v; everything on at idle, around .5-1.0v. You can check this if you unbolt the fuse box, flip it kinda over, and just probe the backside if its plug. If this all looks good, check idle speed, main fuses, batt / alt condition. (Oh, and the ELD is the box w/ a metal plate going thru it, & connected between the 40A & 80A fuses @ the front of the fuse box, and rt by where the batt & alt lines are connected). Good luck to ya.

oh, and here's a link to a doc I got here on Honda charging diagnosis. http://www.smpcorp.com/download/view/Tt1Q98.pdf

That link is the shizzle for an overview and diagnosis of the ELD and charging system.
