I suspect a defective alternator...If you have a voltmeter, set it to read 12 volts...Read across battery terminals with engine off...Jump start vehicle and read across terminals again...Must read at least 2,8 volts higher..If not alternator is defective...If good there is a current drain on the battery when engine is off...Check for any lights remaining on...If you have a under-hood-light this is probably the fault...Remove bulb

If your is exhibiting the same signs as a dead battery it really sounds like your alternator is bad. If you are handy, you can remove the alternator and take it to an autoparts store like autozone and they will test it for you. This is not a hard job to do, usually 2 electrical connections, 3-5 mounting bolts and you have to pop the belt off. Just reverse it to install a new one. Good luck! - Nick

Why is battery draining ford 2002 Taurus SES


Remove negative cable from battery, connect a test light to negative terminal, opposite end off light to negative battery post. ( let sit for 3 to 5 minutes). Then start pulling fuses, when the light goes out that's your bad circuit. God-Bless! Its worth a try.

2007 GMC Yukon Denali engine reduced power


there are 2 conditions that will trigger this SAFE MODE that the engine is running in. The first is transmission over temperature when the sensor in the transmission senses over-temp situation it reduces engine output to no more than 1500 rpm. The second is low oil level in the engine, which will also limit engine rpm to 1500. One of those sensors is bad or the wiring for one of them is damaged. This SAFE MODE is designed to protect the engine or transmission from further damage.

I have a 2000 Denali that just turned over 200,000 and has never given me any problem until 2 weeks ago. I went to start it and it turned over and acted like it wasn't getting any fuel but wouldn't start...


Well, if you jumped the battery and it started, maybe you need a new battery. Get that checked out first. Also, when was the air filter replaced? I would probably take to an indy shop if it wasn't the battery or air filter because it could be a bunch of things: starter, fuel pump, fuel filter or fuel injectors.

Does or did the check engine light ever come on durring all of this ? Or did the alternator light ever come on durring all of this? Jump starting another vehicle, damage to your battery I duoght it, damage to your Alternator and or other electrical componants highly possible if not connected properly.The new battery going dead again could cause all of the problems you have discribed for me. If I were you the first thing I would do is check the new battery and see if it has gon dead now. If so check to see if it is Frozen. If it is frozen you will half to replace it, because once a battery has frozen it will never hold a charge again.Once you have replaced the battery with a good known one (fully charged). Start engine and warm up to normal operating temperature and then disconnect the battery if the engine keeps running then the Alternator is fine . If the engine stalls then you need a new Alternator.A bad Alternator could have ben the problem from the start.I also live in a cold climate zone ( RedDeer, Alberta, Canada).Good Luck and have a good XMSS.

It sounds as if your alternator may have gone out. If you take the Yukon by an autoparts shop (Checker, Autozone, etc.), they can run a quick charging system test for you. Good luck!
