I replaced the alternator on my 1997 Ford Taurus as it was not charging the battery. Now the car will not start and has a dry crank. I checked all the fuses and found them to be ok. I am looking for advice on what to look for next?

check fuses and wiring connections --was the battery tested before alternator was replaced --test battery and alternator battery may be failing or has failed --alternator improper wiring -or new doesnt mean free from defects

Battery Light usually means the alternator is not charging correctly and needs to be replaced. Check charging volts, it should at 14 volts or very close to that number. If the number is low below 12 then the alternator needs to be replaced.

Note: A bad alternator can damage the battery & vise versa

I looked at info for your security system, it is starter motor disable. I didn't see 06 ford Taurus in my database, so I looked at 05.
Battery has a full charge and battery connections all good?
We can usually do some tests to see if starter motor will crank the engine, but, if the security is the problem, it still won't start.
You can check for applicable trouble codes? Try a different key?

You would need to check the connections on the back of the alternator with a meter.
You should have battery voltage on the large wire and on the orange yellow wire.
The other two wires involve the engine computer which turns the alternator on after the engine starts.

Hello and welcome to FixYa!

Try replacing the battery connectors. Check the alternator wiring and battery cables if they are corroded. Something prohibits it from charging and one of it is corrosion.

Hope this helps and thank you for using FixYa! Have a good one!

check your battery terminals first

check the alternator fuse and grounding

When you say it check ok, can you please explain what you mean in more detail, because if your Alternator light comes on or is dim, your alternator is likely not producing enough amps to fully charge the battery. The battery may test good, but the alternator has to work too hard to keep it charged. Have a check run on the amperage output on your alternator to see if it produces the factory recommended amperage. You can get a tester or probably borrow one from Auto Zone auto parts if there is one near you. If not, you can buy an amp tested from your local auto parts store or you can take it to your local shop and they might test it for free.

Does it crank with a jumpstart?

If so, then have the belt to the alternator checked. Do you make short trips? It may just take that long for the battery to discharge enough to not crank the engine.

the alternator is still not charging be sure to check all the grounds on transmission and be sure the plug that goes into alternator is not melted or damaged you may have gotten a dud alternator some aftermarket rebuilds are **** please rate -jeff
