It is possible that the alternator failed and took out the battery. while the vehicle is running disconnect the negative battery cable if the engine dies the alternator is bad.

2002 mercury montaineer , battery light comes on , they gages shut down couple minutes after then the truck acts like it gonna shut off....when getting a jump, the truck fires right up, couple minutes...


Your battery is definitely low. First clean the terminals on the battery and the inside of the terminal rings on the wires. If you have a slow charger put it on that overnight and see if it holds a charge. If it still keeps depleting or doesn't charge overnight then either your battery or your alternator are done....possibly both. So take the battery to have it load tested. Most places that sell them can test them. If the battery is done replace it then test the battery with a volt meter. If the old battery is still good put it back in the vehicle and test the voltage with a volt meter. With the engine off the voltage should read 12 volts (once its fully charged or if its new) with the engine running it should read around 14 volts. If it is way higher than that or it doesn't go up at all your alternator requires replacing. Alternators are fairly easy to replace but if you don't feel comfortable with that take it in to a mechanic.

i would have the battery checked out 1st, it could very possibly have a bad cell in it. if battery checks out ok, then have the alternator checked out.

Security light flash no security system on truck


sometimes turning the ignition on 3 times quickly without starting will reset the computer. If the van has power locks and keyless entry then try using only the keyless entry. Sometimes your car wont have a alarm but an anti theft device which will not allow it to start if it goes off or something triggers it.

Red blinking warning light beside clock in center of dash. What is it?


This is the factory installed "Security" light. It blinks to let you know that the security system is active, and to ward off potential theives. It's part of the factory anti-theft system. Also, it is a diode, and consumes virtually no battery power.
Normal condition; nothing to worry about.
