Ive replaced a battery and the alternator, the charger, and still nothing. It wont keep a charge, it will run when the battery is new/charged, but after that it drains down, then it wont run and cuts out. when the battery is completely dead, it doesnt start at all, cuz theres no juice. can anyone help someone told me it could be a cable a fuse link cable??? running from the starter to battery, then only thing i havent replaced, can anyone help?

Usually this happens when there is a light or something on when the car is not running. You need to disconnect the battery and connect a lamp betweem the disconnected battery and the removed cable or better yet an ampmeter. If the system is drawing current, then start removing fuses until the light goes out or the ampmeter indicates zero. Then trace that circuit.

Is it not the same thing?

When your car runs, measure the voltage between terminals. It suppose to be around 14 volts. If it is lower - your alternator is bad.

You can check the voltage at the battery while it runs, and the voltage at the large charge post on the back of the alternator (where the big fusible link runs back to the battery)...

If you have charging voltage (13.5v or better) between the post on the alternator and an engine ground, but dropping battery voltage, the link is bad.

how do i measure the voltage?

how do i measure the voltage?

Voltmeter connected to engine head or block or battery negative on the negative lead, and to the charge post (for checking alt output from regulator) or to battery positive (to read battery voltage) on the positive lead.

You can get a cheap voltmeter at most stores for under $15, be sure it has a 20v DC range, or it won't be much use...I've even seen ones that just look like a test light, but have a segmented LED readout that reads voltage from 9-15v...they work good enough for what you're trying to do..all you are trying to see is if:

Battery voltage is higher when engine is running, or drains...

Voltage at charge post on alternator matches what you read at the battery, which would at least indicate the link is undamaged.

You probably also have a fuse for the charging system in the underhood fuse/relay center...I forget, did you check that yet?

On domestic cars the charge link usually runs from one of the small terminals on the starter...but on the older Hondas I THINK it just runs directly from the alt to the battery...but I can't swear to it...you'll just have to follow it and see...

If the fusible link is the 80 amp fuse, it is located in the engine compartment near the passenger side firewall (engine compartment fuse box) If it is open, a whole bunch of things won't work when the engine is not running, namely those things that run off the ignition switch, headlights, etc. So if you can turn on the ignition switch and get dash lights and the headlights work, the fusible link is good.

I think the first thing I would check would be the conections! Just a thought but it has happened to me in the past (last year). My connections were loose at the starter solenoid which gave me all indications of a failed battery.
