You need to know Battery Voltage is very important for PCM, Sensors and so on.
With a voltmeter on the battery terminal engine off, with a good full charged battery you should read 12.6v. If not the battery needs to be charge.
Clean battery"s terminals for a good connection and ground terminal body side.

Hope it helps.

Most likely...seems like you have a handle on it. There may be wiring diagrams available, for example Chiltons manuals...To my knowledge there exists no "internal" wiring diagrams for alternators of any make.
Good Luck

1998 Mitsubishi Montero Sport will not run correctly after replacing alternator

My first thought was that when he replaced the alternator, he tightened up the bolt that holds the wire on too tight, snapping off the wire on the inside, these are to be only snug, not really tight. I now would have to say that the alt is grounding out on the inside, causing a short between battery hot and ground, which means charge sometimes, sometimes not with the shortcut wire on. Check to make sure your battery is in good condition and will hold a charge. Do not tighten that wire down real tight, its easy to break off. Once the lock washer flattens out, give 1/16 of a turn, no more.

Ford escape alternator

Place a voltmeter on the battery and read it before and after it starts. If it shows an increase in voltage, then the alternator is working. The voltage goes down as the battery becomes fully charged. Many garages will check it for free.

Can't keep the car running

Make sure that the negative and positive leads to your battery are not switched. If that doesn't work you might need a new computer.

My battery kept going down found out i needed a alternator replaced it allso but battery is still dying

run a wire from the back of the alternator off of the stud in back of alternator to battery positive post.
I have done this before on chryslers the ammeter in dash burns out and it does not charge battery no more.
By running wire from back of alternator it will charge the battery.

Starting problem, battery? alternator??

Unless you have good jumper cables it would start easy since I didn't get in on the begining of this I will assume you have a bad connection tothe starer or a bad starter if it drags.

Ijust replaced the battery on my 1997 ford and battery is drainin

I've put in hundreds of alternators sometime a new one doesn't work properly you heed to check the voltage output of the vehicle running to see if it's charging or simple remove the negative battery cable while the vehicle is runnig, if it keeps running the alternator is working if it's dies it's not but you need to know the voltage output most vehicles it's 13.5 min.
