    You say charging problems; Will it not keep the car running? Will it not keep the battery charged? I'd like to help, but please be a little more specific about the issue.

I am assuming that once battery and alternator were replaced it started o'kay, but then it would be dead. Either the ground is not good, battery clamps are bad or there is a dead short that is causing the battery drain. To find what is draining the battery is not going to be easy, I would first start with disconnecting the battery cable over night and in the morning hook it back up and if it starts then I know for sure there is someting draining the battery. Might be a radio a light like in the trunk or inside the glove box etc. hopes this helps tim

Where is the Alternator fuse on my 1999 Cougar v6 2.5l?


its built into the alternator. have you checked the voltages on the battery before starting the vehicle, then checking the voltage with the engine running, with engine running it should be around 14 volts with out engine running it should be about 12.06 v or higher. anything 12.04 v or lower there is a problem with the battery or there is a short somewhere and thats draining the battery.

I have a 99 merc cougar with new alternator and battery in car can not get the car to charge check the fuse inside the car and the ones under the hood is there a inline fuse on the motor your some were...


When you turn the key on, does your charge light come on? When working right, the charge light comes on with key on, then when started and alternator is working, the charge light (or battery icon, whatever) will go out. If that light doesn't come on, it may have a burnt bulb or wiring problem, and that will keep car from charging.
If that's alright, you must have a loose connection or wire not connected between your battery and alternator. Also, check your grounds: battery, engine to frame, ECM (likely on top of engine).

Cougar 1999 lights flicker after changing alternator have 14.7 volts on output


Voltage regulator is not doing its job, and it is allowing excessive voltage into the circuit. If you do not address this problem, some light bulbs and LEDs might start to burn out. Either replace the voltage regulator, or modify the circuit between alternator and regulator to match later model cougars, where this problem was solved.

I have a 1999 cougar and the charging systems power fluxuates causing the lights and motar to pulse


Same thing with my sister's 99 cougar. Her alternator is brand new and when it was replaced he had a hard time with the alternator cable so I'm thinking it is a loose wire to the alternator causing this to happen. It's either that or the brand new re-furb AutoZone junk alternator which I have had issues with in the past on another car. Check your main alternator wire and also check your battery posts for corrosion.
