1994 honda accord lx battery light comes on &am & engine looses power what can be the problem?


I would check alternator, does the car stay running if you unplug the battery + after starting it? the car should stay running with alternator power alone if the car dies alternator is bad. if it does not you have to check ignition, fuel delivery or compression.

I have a 1997 honda accord and my guages go dead all the lights on the car shut off when i start it then it only stays runing for a couple of sec then dies i tested my altornader and it failed


if alternator is bad you are not getting enough power for the lights etc, just battery power, and that is for starting vehicle if it has voltage. if alternator is good, it should put out at least 13.6-14.2 volts at battery with engine running.battery with car off, at posts should be 12.6 or better at battery. so if alternator is bad it needs replaced. needs proper voltage for pcm also. good-day !

I have a 1989 honda accord exi , its either the alternator or a bad ground somewhere , how do i determine if its a bad ground running down my battery , or if its my alternator


You can follow the ground from the battery to the frame. Cleaning the connections to the battery and the frame including making sure the frame is bare metal where the ground bolts on will usually fix a ground issue. If your alternator is bad it won't charge the battery. But it won't drain your battery. An easy way to test your alternator is to start the car, and remove the positive battery cable. The vehicle should be able to run off of the alternator with no lights on. Hope this helps

My vehicle will not start. the engine makes no sound, so what may be the problem and how do i fix it.


if you have coroded battery terminals clean them with water and baking soda and a wire brush then reconnect them and seal them with vasoline then jump start the car also if your terminals are corroded most likely the battery is shot and the alternator will burn up trying to charge a weak battery so replace the battery if bad or you will be replacing the alternator soon as well

Alternator problem


1.You need to install a Fully charged battery, before you install a new alternator. Otherwise it will burn the alternator up.

2.I read what you typed about installing a new battery. Was the new battery fully charged, and was it installed before the new alternator?
No?
See number 1 above.

Wire burning in half when ignition is turned and wont start


A seriously shorted alternator can do this too.
Try this:
- Disconnect the negative terminal of the battery - Replace the fried wire - Remove the lead that runs from either the positive battery terminal or from the starter terminal to the alternator; the idea is to get the alternator out of the circuit temporarily. - Reattach the positive battery terminal (if it had been removed) - Reattach the negative terminal - Try starting the engine
If the engine will now start and the wire you replaced doesn't fry again, the alternator is badly shorted and will have to be replaced.

Engine starts for about a second then dies.


It sounds to me like a possible fuel delivery problem or a possible power problem. Lets explore the possible fuel problem first then move on to the power. If it is fuel related then most likely it is a clogged fuel filter located under the hood next to the firewall behind the intake half way down close to the passengers side of the car. It is simple to change and just aggravating to get to. That is most likely the problem with the fuel or a bad fuel pump located under the car on the frame rail under the drivers side door. If it is a power problem the most likely candidate is a bad Alternator causing the battery to go dead upon the initial start up of the engine. it requires quite a lot of amperage to run a car such as this and approximately 10 of the 13 volts to keep it running that a typical alternator puts out when charging the battery up as well. Start with the basics like a bad battery and fuel filter then move on to the more expensive things that it could be like a fuel pump or alternator. Most repair shops are able to fix these problems relatively inexpensively or you can find someone in your area that is a "shade tree mechanic" with the knowledge to do this even cheaper. On occasion I have seen a starter relay (if equipped) that can cause this same issue on many other kinds of automobile. I have never had that in a Honda though so I am unaware if that would be a fix or not.

The alternator is not charging the battery. Has been replaced. Has ignition power. It's running directly off the battery.


To be sure, most major parts stores offer a free check of your battery and charging system. It must be a bad alternator, they can confirm that, and sell you one, or install it for you.countrycurt0
