Warning lights would appear at 3,000 RPM
Aramelli » I noticed my warning lights would appear as soon as i hit about 3,000 PMs and release the gas to coast. They then would go off as soon as i gave it gas again. Once i got to work i sat in the parking lot and tested it. In park i would give it enough gas up to 3,000 RPMS and let go, the lights would come on and stay on. They wouldn’t go back off again until i gave it some more gas. My Gas light, and Service light were the two brightest of the lights that came on and the rest were a on but, not as bright. I just purchased a battery from Wal-Mart abou three months back and decided to get the battery tested to see if perhaps that might have been the issue. They tested my battery, my starter, and my alternator and all came out good. The alternator not loaded was pushing 14V and loaded was pushing 12V loaded just being my radio and blower, my AC doesn’t work. The tech said it could possibly be the alternator but, I would hate to spend all that money and not now for sure. Someone else told me that the fuel pump might be causing the problem.
The below information might help because I never had this problem until this happened.
As i was backing out of the driveway at about 6:30AM in the morning all the sudden my horn just starts going off by itself. I immediately cut the car off w/o puting it in park to prevent from waking the neighbors, I unplugged the horns and went off to work. Noticing the issue on my way to work.
misha » Sounds like you have some sort of short circuit.
Your alternator have normal charge of 14v without any load…but when you turn on accessories it falls down to 12v.
12v from the alternator means that alt isn’t charging.
Check the grounds and b+ terminal and also battery terminals for corrosion or loose.If they look greeny or dirty you need to clean them up with baking soda or alcohol with a tooth brush.
Symptoms of a Bad Alternator
polskamafia mjl » I don’t believe that turning the car off in reverse has anything to do with your problems. 2 weeks after I got my 850 I spun out into a corn field after a heavy rain. My car was rolling backwards while in drive (aka, it should have been going forward), so I pressed the brake pedal and turned off the engine while in drive. After all of this, the only thing that broke was the odometer gear.
Aramelli » It was in fact the alternator going bad. I have since then ordered a new one and will be installing it asap. The car is now completely dead in my driveway.
