Alternators:
Here are the most asked questions about Alternators that I
have come up with. The answers are given in simple terms as
possible.
- How can I tell if my alternator is
bad?
The easiest way to tell if it's your
alternator is, is your battery light on? If it is, more than
Likely it is a bad alternator. If your car won't stay running after
you jumped it. Your battery goes dead over night when you know
that the battery is good. These are the 2 most common way's you can
tell if your alternators bad.
- Why can't I use the old method of
removing the negative cable to see if the car stay's running as a
way of telling if the alternator is bad?
Since alternators started using internal
regulators which are solid state, the system can get a large jolt or
spike when you disconnect it from the battery, and if the alternator
was in good shape can harm the regulator and render it useless. Then
you now have 2 problems to repair.
- What is a remanufactured alternator?
The difference between a remanufactured unit
and a rebuilt unit is simple. A rebuilt unit is a unit where
you disassemble the unit, repair the broken or worn parts, put it
back together and sell it back as a good unit, and a remanufactured
unit is where the case of the unit is striped of all internal parts
and all new parts are put into the case and then sold. This is
the simplified version of it, but thats what it is. You will
always get a better unit and a better guarantee with it.
- When I jump my car, How long will it take to charge the battery?
First of all jumping a car and running it
should be a last resort. A discharged battery should be
charged on a battery charger, not by the alternator. The
alternator is NOT a battery charger. The alternator was only
designed to replenish the battery with current, not to charge the
battery. In most cases the alternator can take on the job, but it
really puts a strain on the alternator and could possibly burn it
out. The time it would take to charge a battery far out weighs
the risk of a fried alternator.
- My car doesn't seem to be charging correctly, what could be the
problem with it?
It may not be your
alternator at all. what kind of condition is your alternator
belt in? Is there black belt dust on
the front of the alternator? If so, you are having a belt problem,
not a alternator problem at all. Check your belt tension, is
the belt loose? Stop in and we'll tell you and adjust it for
you, if it's bad we'll replace it for you. If you let the belt dust
collect on the alternator, in time you'll find out that the dust
will make it's way into the alternator and give you charging
problems.
- Why is it so hard to give a good quote on how long it will take
to replace my alternator?
The truth is, I
can go by the book and quote you, but as alternator specialists, we
at times have found our own little tricks to get the alternator out
and back in faster than what the book calls for and we try to pass
that savings to you. On the other hand you may have a car with
an extremely difficult unit to remove and learn to find all the fast
ways while we repair your car. We always try to get you going
fast, because we know your time is important. In most cases it
takes longer to charge your battery than it takes to do the
alternator. It is very important to have the battery charged
correctly before the vehicle leaves to ensure your alternator is
performing well before you leave.
