It's best to relate symptoms to narrow things down. I assume you are still getting a dead battery when trying to start even after replacing the alternator and battery.
Get a volt meter. Harbor freight sells them ridiculously cheap (about $5). Measure the voltage at the battery terminals when the engine is running. If it is at least 13.5 volts to 15 volts then the alternator is charging correctly. If it is 12 volts then the alternator is not charging the battery.

If the alternator checks out ok, then check for things that could be draining the battery when the car is off. Usual suspect is the trunk light. Put your cell phone on video record into the trunk facing the light, then shut the trunk. If the light stays on, its because the switch in the latch mechanism is faulty. WD40 might make it work, or just pull the bulb. Also, check the glove box light the same way. Good luck...Chris

I have a 1993 mercury capri convertible. I have replaced the water pump and the alternator which the vbelt sits on. The alternator belt squeaks and burns and breaks when it is on tight. I loosened it up....


Most after market replacement alternators have the wrong pulley installed...the shafts are different sizes, so you cannot even use your old pulley. Best is to have the original alternator rebuilt. Alternative is to use a heavy duty industrial belt, like a Gates...not a perfect solution, but it will help...good luck...Chris

Is there a wirer that runs from the alternator to the battery on a 1984 mercury capri. The car is not charging the battery and I replaced all the battery and starter cables


From the alternator the AC is converted to DC and regulated so as to make a controlled charging at all levels of the alternator RPM when the engine revs. This is to keep the high voltage of AC to DC from damaging the battery and so the regulator/controller is an important part.
So you must first check your alternator voltage/current , then the controller regulator and the battery voltage change can be seen with a voltmeter across it. Also the currrent to the battery can a be checked with an ammeter in parallel.
So check these tips and comment.
