My son has a 1994 corolla. starting of the engine became more difficult over a period of time, then it failed to start altogether. the engine does not even crank.
1. had the battery tested = good battery
2. replace positive terminal cable = won't start
3. replaced the starter = engine started about 4 times and even ran well for a day.
Now engine wont start or crank. when i turn the key in the ignition i noticed the clock dims out almost completely when trying to start. Need help ...many thanks
The problem and symptoms are typically caused by a dieing battery, starter solenoid contacts not making a good connection, corroded battery terminals, bad battery cables.
Try jumping the cars battery and see what happens.
Check battery ground terminals (both ends and cable). Sometimes the connection between the terminal and cable can be bad.
Assume you changed the solenoid along with the starter.
If you can jump the starter motor itself with a battery cable to determine if it works now.
There may also be a grounding strap between the engine and chassis, make sure this is in place and OK shape.
Yeah make sure all the grounding points are secure and free of corrosion. Worst case scenario would be that the flywheel ring gear or starter pinion teeth are loose or broken, but hopefully it's something simple.

what volts you reading in the systems? do you have a digital multi tester?
fully charged and good should be 13.8 volts or damn close to it
if all wires and connections are clean tight and dry then the alternator is probably stuck and is junk ,
i had this same issue with my 93 corolla in which i have another alternator to replace it with now, from a 99 durango,
is also the same size nippondenso alternator so i can make it work fine and was free left over from engine replacement job last weekend..
on my 93 the alternator charging wire/post was draining the battery down and it would be dead in a day's time
you should check yours by seeing if the battery cable makes a spark when you tap on the battery post, or use a test light inbetween the charging wire and the charging post after removing it real quick
if the test light lights up in series between the post and the disconnected wire then it means its stuck and drawing off your battery and draining it
bad alternator
common problem on these it seems

It seems that the battery is dying. If you can make it start again. please check if you can disconnect the battery cables without engine dying? do it also with your headlights on...
If the alternator is not supplying juice to the battery then its not charging, then you will just keep using the battery until it runs out of juice too... symptom no. 3 on your post.
please check if you can disconnect the battery cables without engine dying?
Dont EVER disconnect your battery while the engine is running. You could get away with that in the 60's with cars that had no electronics, but in todays cars doing that can cause a nasty voltage spike that can kill electronics that will make your life hell to diagnose.
Spend $5 on a multimeter that will tell you if the alternator is doing its job.

Ok Speedy is correct and i came from old school cars so listen to him... but Speedy you did not elaborate on how to check it using multimeter? what and how to check it? what reading should we expect or where to put the multimeter? are we looking for volts? if the battery is connected then are we reading the battery or the alternator?
With the engine running, put your leads across the battery terminals to measure voltage. You want to see a minimum of 13.2 volts. Most cars these days will put out 14 volts. If it goes over 14.5 you have a faulty regulator and it will cook your battery. A good battery at rest will measure around 12.5.
