Question about 2000 Mercury Cougar

3 Answers

My 2000 Mercury Cougar starts ok then after a few minutes the dash gages drop to zero then starts to struggle to keep running then dies and will not restart unless I charge the battery. I was told maybe the alternator isn?t kicking in, but had tested at AutoZone and they said its good; just maybe something is telling it to shutdown. Please help me

I have the same car. Same problem. We replaced the fuse box and it fixed the problem. But here we are 6 months later and the problem came back. So for a quick fix you can replace the fuse box. I'll let you know what the real problem is when i get it to the dealer.

I suggest you take to auto-zone with a fresh charge on the battery, have then test to see if the alternator s putting out voltage , if not try full fielding the wire on the alternator and retest for power from alternator, if it does not charge then do like the other guy said run a positive wire straight from the battery to the output side of the wire on the alternator, then try running and do a voltage test if it's not producing 13.5 volts output then the alternator is defective, if it runs the battery down sitting overnight then the didode trio may have blown and the diode is allowing connection threw the armature going back to the battery, I am not sure if this model has a separate voltage regulator but if it does then you will have to test the voltage regulator, you will have to get a diagram for it and full field the regulator to see if it will charge correctly, when testing you need to have a volt meter connected to the battery to see if it gets 13.5 volts on each of these tests you do. (Warning) do not do this test with low battery as low voltage will cause a high amperage condition and can cause you to burn out computer and other devices, do not let the battery get below 11 volts. If the dash lights go dim it is indicative of low battery power try using a battery charger on low to keep the voltage up and see if the lights and dash dim or go out. If notthen it is a charging system issue after running these test let me know what you find and I will give you more ideals to test without just changing parts. It is imperitive you have a digital ohm meter so we can test diodes and not burn out other componets.

Check fuses alternator fuse ,charge fuse.also if that checks out look at the harness for back of alternator is it in bad shape? is there a large wire by it self bolted on the alternator? if so take a wire ,same size,and bolt it on with that wire and run it directley to the positive battery post this will charge battery for now on,but if u dont have a large wire bolted on alternator ,the larger wire that is pluged into the alternator is the same wire ,tie into this wire really good and do the same (run to battery positive post) make sure this plug in is good ,if not u can purchase this at the zone

You can disengage alarm with a remote if you have one otherwise, close bonnet, all doors and lock the car by turning key completely to the left and right few times and do the same to unlock. This will dead lock and unlock the car. When you hookup the battery make sure you connect red wire first and then the black one.

Sounds like a fuel problem. The electronics shutting down are the result of the dying power. Start by changing the fuel filter. If that doesn't work; I'd look into the fuel pump.

Mercury cougar wont start


My first suspicion is the battery connections may be lose and also the battery may now be run down. If you take the terminal connections off and clean them and the terminal posts so that they are shiny clean and charge the battery you can try again. If the car starts, that was the problem. If it doesn't, then look for the starter solenoid and lose connections there and also look toward the starter next. A tech with a volt meter can run independent checks and narrow it down further but having good connections and a charged battery are necessary to get started with the other tests.

My mercury cougar won't start, all lights are ok


Take another look at the battery, clean the posts and the terminal ends. Charge the battery, or jumpstart from another vehicle, and allow it to run for 5 to 10 minutes. Shut the vehicle off and see if it will start again. If not you will most likely need to replace the battery.
