It sems like you have oxade in ECU contakt, i had same problem but with PGM-FI light, i took it out (ecu) and cleaned oxide around those aluminium contakts and inside ECU it self (in holes for wire). now problem free

[accord89carb]

please can you tell me where ECU should be in my car i mean is it in the hood or interrior?do you have the picture?and i like to know what is PGM-FI light?what do you call that thing which you cleaned your car ECU?

it's underneath the driver's seat and you should get a manual they help alot with this kind of trouble shooting

Well, since you kept pulling the bulb out a few times, check to see if the filimant in the bulb is good & the connector pins inside it are making good contact. Another way to see if the alternator is charging is to hook up a voltmeter to battery when the car is started, should be reading about 14.5 volts. The voltage regulator is in the alternator too.
On carb models, that box under the seat is for emissions crap.

i checked the filimant in the bulb and the connector they all r good. emissions??sorry i didnt understand so u mean i dont need to cheack the box under the seat?its nothing to do with the beterry light problem?and i like to know one thing more when i take out the bettery bulb in the speedometer then the car bettery doesnt charge do u think it should be like this?

[ghettogeddy]

is the alt or the battery any good just wondering cause normally when the light goes on it means the alt or battery is to blame and u have to take the switches out of the dash on each side of the wheel there are screws behind it

[88Accord-DX]

That box under the seat is for emissions, nothing to do with charging. There is a charging light indicator in the circuit. (which I think you pulled out)

I don't have a better wiring schematic right now other than Chilton & Haynes.

2 months ago the belt was sliping and making noice like when the belt slip i did tight the sound went off but the light use to come and go but when i use to put the key on ACC I USE to see the battery light now when i put on ACC the bettery light goes off after 1 secound so this is the main problem i want to know what it could be.the bettery is good and look like alt is good too.

[accord89carb]

like you said There is a charging light indicator in the circuit. (which I think you pulled out) are you talking about in the speedometer?

[ghettogeddy]

u cant just look at the alt have u had it tested u can test them while there on the car i would def test it first

There is an old school way of checking the alternator since your carbed & not much to worry about. While the car is running, pull the negative battery cable off the battery. If the car stays running, the alternator is good. If your car dies, the alternator isn't working. (don't recommend this on cars with ECUs or PCMs)

[accord89carb]

i pull the negative battery cable off the engine is still running

[88Accord-DX]

Good, sounds like everything is working. I wouldn't worry about the battery light going off after one second in the ACC position too much.

[accord89carb]

there was a problem with bettery light when i use to put on acc after 1 secound the light use to turn off well since i took the bettery wire off and connect again now its working normaly. i took out the better wire and there should be bettery light comming i didnt see that after 2 minute the engine stop it self so it look like there is a problem with alt.am i right?

[nskforlife]

dude, just take it to your local autoparts store and have them check everything.
i should've got all my stuff checked but i didn't and i paid the price.
alternator was bad, but it took me replacing the starter and having the battery charged to figure it out.

go get your electrical problems checked out at an auto store. and dont tell them what you think is wrong, just tell them you dont know and need everything checked. from the starter to the battery, alternator included.

[Crazybird]

good thing ur alt is good cause its kinda bitch to get out

[MessyHonda]

idk if any one has said this yet? but have you checked your grounds?

[accord89carb]

how should i check the ground?where can i find ground wire?is it the same ground wire which is connect on the engine valve cover and going to the body?and please can you tell me if i want to take out the alternator what is the easy way to take it out?

2day i start the car and didnt start the heater,stereo,healight i left the car start for 15 minutes then i didnt see any betttery light comming because the bettery was getting charged i noticed when ever i play stereo,switch on headlights,and heater fan then the interrior light goes dim then the bettery light comes after 10 or 15 minutes so what you guys think what it could be?is it a carbon bush which is not charging correctly or some thing else.

Probably need to yank that alternator out & have it checked to see if it is working right without a good Digitial volt meter.
