CHANGE YOUR VOLTAGE REGULATOR DRIVE SAFE It might also be a good idea to go get your alternator checked. Autozone/Advance Auto do it for free.
Alternator number is 2-90276-830-2 and MSRP is $505.24. So retail might be around $590.00.
The way the alternator belt raps around pulleys in the automobile differs by vehicle and engine. An alternator belt in an older vehicle usually just went around the fan blade, the water pump, and the alternator. Today's vehicles are more complicated and might require more pulleys.
The bearings might be bad in the alternator.
Acceleration simply refers to the rate of change of a velocity. You might say that the effect of an acceleration - any acceleration - is therefore a change of velocity.
alternator needs to be replaced. battery also might be a problem due to the alternator not charging it
Find a volt meter, check the battery voltage with the engine stopped, it should be a around 12 V. Now start the engine and the voltage should be around 13.5 V. If the alternator isn't putting out about 13.5 (+/- .5 V) the replacment alternator could be bad or you might have a bad connection somewhere.
This might mean the ground is isolated from the case of the alternator. In a normal application, the case of the alternator is the ground connection and being bolted to the engine block via a metal bracket, the grounded case of the alternator is electrically connected to the ground lead of the battery which is also connected to the engine block. An isolated ground might indicate the alternator ground is electrically insulated from the alternator case.
Could be you have a bad belt or belt is loose.. Also it might be possible that the bushings are worn out of the alternator
In general, slowing down is negative acceleration. Some might call it deceleration. Braking a car or bike is a simple example of negative acceleration.
Since you replaced the battery and alternator, you must have had a problem before. Did you run a voltmeter on the battery while the engine is running? Should have around 14 volts. If you are getting around 14 volts, you can assume that the lite might be faulty. If you are getting say, 12 to 13 volts, then the alternator might be faulty, yes even sometimes rebuilt ones. Check all the wires to make sure there is good contact, also if you still have the problem, then you might have a broken wire ( somewhere ). Good luck
