Question about 1999 Ford Taurus

2 Answers

My battery and alternator test good, but something keeps me jump starting my car. But if it sets for a while it will start without a jump. What could my problem be. I don't have a lot of money to keep paying people to tow me home or jump start me. When the car is dead the horn will not blow, nor will the headlights come on. HELP ME

Next time your car wont start & after trying a number of times, run your fingers lightly along your red starter cable & try to feel if there are any hot spots if there is none, do the black ground cable next. If you find a hot spot, this is where the problem is. You may have to change a cable. Make sure your battery connections are clean. The most likely answer to your question is that the starter has developed, what we call in the trade, a flat spot or a place where the starter can not work because of worn brushes or defect in the armature due to wear. Your best option then is to replace the starter with a quality rebuild simply because they are much cheaper than a brand new one. Hope this helps you. Good luck!

There is something draining the battery when its dormant. A decent shop should be able to narrow it down, but you could find it with a 12v test light. the fuses for things like the radio, that shut off with the key off, shoudl have no power when the key is off, if you find power at that radio fuse when off, you have a module or switch not shutting off current. there are also a lot of things that stay on with the key off, you could remove fuses, and relays to each circuit, and use a voltmeter to see if the draw goes away when the fuse or relay is pulled. the usual suspects are trunk/glovebox/hood/interior lights staying on, or the starter solenoid or alternator has a bleed to ground. If you cannot afford a shop, you might contact a local high school auto shop or vocational school. usually its much cheaper, and also you can usually deduct any fee off your taxes (see your tax advisor)

92 Saab keeps dying, won't hold charge....

You have the battery and the alternator and the alternator belt and if they are working fine there must be something that is draining the battery. You need an auto electrician to check what the drain is. In such cases,on various vehicles, the BCM, body control module, proves to have something to do with it.

2004 F350 super duty diesel when jumped it will start but batteries will not hold a charge will not start without a jump. Had batteries tested and tested alternator all good HELP PLEASE

If you are sure the batteries are charged up fully but you keep having issues with having to jump start I would double check the batteries after sitting for a while. Could be a problem that there is a short that is running the battery down enough not to work. Could also be your starter is pulling too much juice as if you put a boost with your battery hooked up you are using a lot more power than just your operating battery. Just a couple of ideas.

I have a 1998 hyundai coupe 1599cc the engine cuts out when idling and i have to jump start it or wait for about half an hour before it will start again

This sounds like a battery or alternator problem.

Lets start with the battery, just because the car starts in the morning does not mean the battery is good, A bad battery will start the car and as car is running and drawing power out of the battery the battery which is getting charged back up from the alternator but if battery is bad and not accepting the charge this will do a few things.
First it will cause damage to the alternator because , the alternator will try to charge the battery with no result and so it keeps charging at high rates and heats up and causes damage to itself , the next thing is battery loses voltage slowly until it does not have enough voltage to keep engine going , inturn engine stalls out,
I would start by first having the battery tested by a shop with a battery tester, the next thing is the alternator , have that tested.

Your problem will be a bad alternator or battery. good day.

1991 ford escort battery keeps dying

Check and clean and tighten all battery, starter, and alternator connections. Also the battery and engine to chassis grounds. Did you have the battery " load tested" as a good test requires?
Take the battery out and have it charged up. If the alternator is good, you should not have any more problems. But if you need a jump after a few days to start it, then either the alternator or the battery is just not up to par. Have the alternator tested while on the car and running.
Good luck.

Short in wire from battery to starter or cylenoid? sometimes it will turn over other times not

I had my ford 91 ranger checked and both were good, plus alternator was in the green? But kept killing batteries and would not start without a jump. I replaced solenoid, starter, and battery. Finally removed the alternator and the BRUSHES were making contact just enough to keep my truck running, but when lights or any other accessory was used the truck would quit. New alternator and starts every time and can run all accessories without problem. Check the brushes on the alternator.

Having problem starting my car without a jump, started recently.

  • Well, if it starts with a jump and runs all day with no problem then that would indicate that the alternator is doing it's job of charging at least. Does the car function normally all day after a jump start? The problem could very well be the battery needs replaced or something is draining the battery overnight and the battery is fine.

  • I would pull the battery and have it tested at your local major parts store. Or better yet if drive-able, drive it the vehicle to the parts store so they can load test it.

  • If it is good then you want to look for a wiring issue. If it tests bad then replace the battery.

  • Hope this helps.

Hello! I do not believe this is a security issue...The Battery Light is telling you that the charging system has a fault...One of three possibilities exist...# 1...The battery can no longer hold a charge...
# 2...The Alternator is defective...Or # 3...The cables that interconnect power and ground are corroded and resistive...Do you have a voltmeter and a wee bit of experience using one?...If not send a comment...Set the meter to rear +12 volts...Place the meter probes directly in the center of the battery post...Record the reading...Jump start the vehicle...Quickly remove the jump cables and while the engine is still running, take the same reading again...The second reading must be 1.8 to 2 volts higher than the first...This tests the alternator...If alternator is good...Have the battery tested...Clean cables (on both ends) if necessary...

When the battery, alternator and cables are correct, the battery light will go out...At that point in time the engine should start...If not, then we have other issues and I'll fix them if necessary...

Check for loose battery terminals. Car will not start without jump because battery is not connected properly. Starter is probably good or car would not start with or without jump. If alternator is bad and not producing current, car would die after running a short while as battery would out of juice and without alternator current the car would die - so probably alternator is good. If connections are all good, get a voltmeter and test the battery voltage - it should be over 12.75 volts. If not, battery is not holding charge.
