SOURCE: On my 91 capri non turbo, the alternator is sqealing

Could be the belt or tensioner(if so equipped) was too tight and then it may have warped the pulley or ruined the alternator. The belt smoking could definately be overtensioned or the bearings are shot in the alternator and creating the friction in your belt. Check the tension specs for most vehicles is usually between 1-1/2 to 2 inches of play. Thats how far your belt can be moved up and down by hand after tensioned. Too tight and you risk burning up bearings in other places or too loose and you hear squeeking and the vehicle may not charge properly or even overheat from water pump not turning well enough.

SOURCE: low alternator voltage

it should be able to deliver 13.5 volts to 14 volts when engine is running. this can be caused by also regulator.it is there to regulate voltage generated by alternator.

How do you replace an alternator on 1991 Mercury Capri XR 2 turbo


Remove alternator, replace alternator. Get your self a service manual if you can't figure it out. They sell them at the same place the alternator is sold.

Can I get a diagram for a removal of a alternator on a 1991 Mercury Capri XR 2 turbo


Disconnect the Red battery terminal first and then loosen the serpentine belt by moving the tensioner pulley with the correct socket to permit slack enough to dislodge the serpentine belt from any pulley such as the idler pulley or other pulley. Pay close attention of how the belt is routed prior to removing. Remove electrical connections to the alternator. Remove all alternator mounting bolts to remove the alternator. I would recommend a Haynes manual from the parts store on your vehicle. I will help you now and well into the future with all problems that may occur. Be sure you have a fully charged battery at all times as a low battery will cause the internal voltage regulator to over heat and burn up due to the need for more amperage than the alternator can generate.

1993 mercury capri charges then doesn't new alternator and battery


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

My 1991 non-turbo Mercury Capri started fine last night but while idling, the Air Bag light began to flash and the Battery light came on. Not wanting to travel I turned off the ignition switch. ...


charge the battery and once fully charged, do a LOAD test on it, clean all the connections and start the car ,, check the voltage at the battery posts with the car running, you should get between 13.5 and 14.5 volts, if not, replace the alternator , if you do, the battery and the cables just needed some attention

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.
