It could be bad connections to the battery causing a low amperage max. from the battery through the cables.

When you jump it you add the power of another battery to the cables on apparently clean cable ends and it starts.

Could be a bad starter, too.

2006 Cadillac CTS help My car was tested @auto zone for the batery n alternator n both passed Good voltage Everytime I go to crank my car it does not crank I have 2 jump it of even if it's for 15 mins


Luis: That makes no sense. But here is what others are saying: " How possible is it for a bad alternator to be tested good? I already had people telling me to replace it.

I got both the battery and alt tested. Both passed.

Reinstalled on the car and it ran good surprisingly after the battery was charged @ the autostore > till after about 10 minutes, then the battery meter dropped back down.

Soon as i turned on the lights/ac the battery meter dripped down real low. SOon as i turned them off the meter jumped back up.


Soon as i revved the engine the headlight would brighten then dim back down after the rev was over.

I can jump the car, but it will turn off by itself if you leave it idling to long then it needs another jump.
Driving it doesn't charge the battery up.. its actually drops the battery meter down more and more and more till its dead.

-Car doesn't drain the battery while its off.. so its nothing left on.


>> Now people are telling me there alternator was tested good, but the problems went away after buying a new alt.
"
Some people say there could be a loose belt not turning the alternator fast enough to supply power to lights/ac and charge battery. Or bad wires". or possibly a bad voltage regulator.

What the electronic control module control on my 2005 cts


Did you check your fuses? You might have a blown ecm fuse or other fuses blown. Were their any additional wires connected to the battery that you may have ommitted? Do you have spark at the coil pack or the plugs? You may have a bad module. How does it sound when you crank it over? Does it turn over superfast? Could be timing. Check all these things and get back to me. Check the fuses and relays under the hood also.

Can I jump start a 2005 Lincoln?


If the battery is from 2005, just replace it

You have to charge a dead battery,it is unsafe
to jump a dead battery

You own the car, so you can jump it or whatever
you want to do,I would replace the battery.

You can get a battery at the ford dealer for
the same or better price than a parts store & it
will fit.

They don't discount batteries to business owners,
so your all set going there,you pay the same as a
repair shop

My key is stuck in the ignition of my 2006 cadillac cts


2005 CTS 3.6 Dead battery, key stuck, service anti theft and nothing happens when you turn key, Ttried everything, ECM reset, key memory reset, charged battery to 12.7 volts, locked door w remote and opened w key, anyway you get the idea. After 3 days of online reading and trying, THIS IS WHAT WORKED, 1. put key into on position 2. removed sarter relay from front fuse panel 3. jumped 1st pin closest to fender and passenger seat with pin that is closest to motor and front fender. I used a paper clip and just made contact long enough for car to start. ran car for five minutes and took key out and everything went back to normal. then I took car to advance auto parts to have engine light reset. if car does not go back to normal you have ECM (car computer) failure. video on YouTube under "no crank, no start"

My battery ran down on my 2005 Cadillac CTS because of non-use, sitting in my garage. I charged it up and it tests ok, but the car wont start and the lock out light is on the dash. If the battery is good...


A loss of power triggers the Anti theft feature on you car. In some cases, if you lock the drivers door and unlock it with the key, you can reset or rearm the system.

Another method is to turn the key to the On position and leave it there 10 minutes. After 10 minutes, turn the key to attempt to start the car. If these 2 methods don't work, you may need to tow it to the dealer to have the Security reset.

Battery on a 2005 Mustang went dead. Had a Jump to get the car started. Drove & speedometer & odometer worked fine. However, I had Triple AAA install a new battery & now they don't work. ...


Did AAA clean the battery cable connections when they installed your battery? Did you check the fuse for the insrument panel?

It could be just bad timing or a coincidense but I am more likely to think things are connected. If your gauges worked after jump starting your car, but not after AAA changed the battery, something changed or was left disconnected.

I have a 2005 Cadillac cts and I bought a new battery and now I have to take the battery off and on to get it started what do need to do its something to do with the alarm or security system the doors lock...


Welcome to FIxYa.com





Sounds like one of the small wires comming from the ignition lock cylinder has broken in 2 and you will need to replace the ignition lock cylinder and keys. If you don't care if the special key starts the car then all you have to do is measure the key resistor and go to radio shack and buy a resistor close to the same reading and cut the wire at the bottom of the steering column and wire the resistor in place. Then the engine will start up





Thank you for using FixYa.com
