Does alternator affect acceleration?
The falls in the electrical power of a broken alternator can cause a malfunction of these systems, leading to a malfunction of the engine. Symptoms will be the slowing down, the failure, the poor acceleration, the hesitation and the stalling.
Can a new alternator fail?
It makes sense that when a new alternator fails after only a few months, any car owner would want to know why! We have found that one of the most common things missed by technicians during alternator replacement is a careful check of the battery; this is especially important for a battery more than three years old.
Why does my alternator run when I Turn Off the car?
Generally, an OEM harness will not have the problem of alternator “run-on”, as there is usually a resistance wire in the dash harness to keep this from happening. Solution: To figure out where the problem exists, start the car and with the key in the ON position and the car running, turn off the key.
What did I do when my alternator died?
I was driving on the freeway and my car started to make a weird noise. Pulled over to the next lane for the next exit. It automatically died and locked up. I kicked it in neutral and forced it onto the shoulder. Roughly a week or two before that I replaced the alternator and it was running great.
Why does my car run when the ignition is turned off?
With the ignition turned off and the car continuing to run, simply remove the plug from the alternator (DO NOT TRY AND REMOVE THE BATTERY POWER WIRE FROM THE POWER STUD!) and the car should shut off if the alternator is creating the problem. If it does not stop running, your feedback problem is coming from something other that the alternator.
What kind of car will start after a jump?
I have a 2004 Kia Spectra 1.8, I have replaced the spark plugs, the alternator, and my battery is only about two months old. The car will start after a jump but it has to sit for about 10 minutes before the jump works. I replaced the alternator and the car started off of a jump and even started back up on its own.
