Hey guys just wondering if anyone can help me out....My batt light has been on for like 6 months now...The alt had 14.8v while running and the battery charged I never had any problems so I didnt worry about it...Well went to get my car tuned and started having issues, and now im having issues with my car dying once in a while when driving...I replaced the alt, batt, redid the grounds under hood and regrounded the neg batt terminal...????? The light some times goes off when steady on the gas but when you let off the light comes on...Im lost any help would be great ???

Thanks

There are two different wires running between the alternator and fuse box. One of them may have an open or short.

 

The white/blue lead at the alt. is what "controls" the alt. light by supplying the light with a ground, [12V+ for the light is supplied by fuse 24 - 15A, hot in run and start, it also supplies power to the alt. exciter lead, black/yellow].

If you replaced the alt. then the alt. is not the problem, the problem may be the ICU as the white/blue lead is connected, parallel, with the ICU and the ABS control unit, [if you have ABS].

 

No I do not have abs in a 92 da rs....Ill be working on it tonight, ill check out the wiring leading from alt to fuse box

 

Is there any way to check to see if the ICU is bad other than buying a new one?

 

Do the front side markers work properly, blink on when using signal lights or hazard lights, turn on when park/head lights are on, blink off when signal/hazard lights are used and park/head lights are on?
Do the intermittent wipers work?
Does the rear window defog work?
Do the warning chimes still work, [key still in ign., lights still on, seat belts]?
Does drivers door turn dome light on when opened?

If any of the above are not working it could be a problem with the ICU if more then one of the above is not working it is a good bet the ICU is bad, very common on G2s and other older Honda/Acura. 94

 

The funny thing is all of the things on your list are in perfect working order!! lol any other ideas? Im leaving for vacation hope to see more suggestions in a week

thanks

JJ. your car is just junk!!!! haha. j/k man. we gotta get together soon.

 

It does not rule out the ICU, it is still what I would want to check, you have already replaced the alt., batt. and redone the grounds, the ICU is the only other thing in the circuit that I know of.

With that said, I can't see how the batt. light staying on would cause the engine to stall, "and now im having issues with my car dying once in a while when driving" that sounds like a diff. issue.

Question...
Will it start again after "dying", if not, does the engine turn over, [crank] and just not start or will it not even turn over, [like dead batt]?

 

Well when im watching hondata the injectors shut off, right when i push the clutch in the car goes back to idol and will drive fine for a while, then they shut off again...when I get home I will check the icu

haha kerry come help me fix it when i get home from flordai

 

If the injectors are shutting off I would check the PGM-FI Main Relay, it is what supplies the injectors with power, the PGM-FI Main Relay is also a problem on older Honda Acura.

This may help... http://www.tegger.com/hondafaq/mainrelay.html 94

 

ok ill throw one of my other main relays in...I just figured the car started fine it would be that, but I guess one of the soter joints for the injectors could be bad....I suck at spelling

 

So do I, that's why I have the google tool bar up at all times, a very good spell check. 94

 

haha good idea

 

hey tegman, I'm currently having a similar problem to yours. my light only comes on when I start it, but once I rev it a little bit, it goes away. I am not good at trying to diagnose this thing, so I need help....please. another thing I noticed but only happend once, was my fuel pressure gauge on the fuel rail was fluctuating up and down when my tuner was trying to start it. it was going crazy. stumped and was reading this, so I thought I'd ask, thanks

 

well if I figure out my problem ill let you know...I just got back from vacation and my car is getting a roll cage right now
