Default Electrical Problem w/ my 89 Honda Accord

Hi and thanks in advance for any help,
My problem is my battery is no longer being charged while I drive the
car. I've had the battery tested and it's fine, the alternator has
been tested and it's fine. Could the voltage regulator be bad? I
would be able to at least start the car for a period of ~24 hours if I
drove it for about an hour each day. Now, it won't start at all once I
shut the car off which leads me to believe that the battery is no
longer being charged at all while I'm driving. After I jump the car it
runs great.
Thanks for any help.
-Jason

It may not be related to your battery if the car is not starting but
who told you the car is charging ok?

What sort of voltage do you measure across the battery with the car
running? It should be 14.5 V. Turn the head lights on. The voltage
should not appeciably drop.

Turn the car off but leave the head lights on. The voltage may drop to
about 12.5 volts or so but should not drop appreciably below that
voltage.

If it does drop and the car does not start, my first suspect would be
the battery or the wires to the battery (including ground).

If it does not drop yet the car does not start, it could be starter
related. Perhaps you have a bad connection from the battery to the
engine. See if hooking a booster cable (negative side only -- leave
positive hanging) from the battery (-) to a large hunk of metal on the
engine helps the starting process. If it now starts, you have a bad
contact in your ground.
Also check the wire from the battery (+) to the starter - it could be
that it has corroded contacts.

The above is absolutely where I would start.

Also, how old is the battery, in years and miles?

How many times have you jumped it now?

Jumping does reduce battery life.

A bad battery will reduce the alternator life.

www.autozone.com has a manual specific to your car free
online. It should have directions similar to Remco's for
checking the battery and charging system, which should be
like the following, on page 10, for a 91 Accord.

Thanks again for all the advice...

I measured the voltage across the battery with the car started and it
measures about 15v. With the car turned off it measures about 10v and
just slightly under that when the headlights are turned off. I did
notice some corrosion around the positive terminal so cleaned all of
that up. However, after driving the car around for a bit to get it
good and charged it still won't start when I turn off the engine. I
just get what amounts to a repeated "clicking" noise. Is this the sign
of a bad starter?

Also, I can't verify the age or milage of the battery. However, I have
jump started the car many times (20+) over the last couple of months.

That 'turned off' voltage sucks eggs. Replace this battery.

That sucks scrambled eggs. Replace the battery. Report back.

Interstate is a fine brand and may be what Honda is
currently using. My dealer's prices are /very/ competitive
with places like Firestone for Interstate batteries. (I
sense a trend in this direction for all Honda parts, as a
matter of fact. Internet competition may be working!)

IIRC, a few months ago my dealer wanted $65 for an
interstate battery with a five or seven year guarantee. Very
good price for what's said to be a very good battery. (My 91
Civic's latest is an Interstate, for which I paid 83
something *&^% dollars at Firestone 1.5 years ago.)

I agree that the battery looks bad but there is another remote
possibility:

You should have a lot more than 10V on the battery with the car off off
unless something is drawing some major current. That would be almost
hard to believe, but let's make sure:

To alleviate that as a possibility, first put on some safety glasses -
you don't want to get hurt.
You won't get electrocuted or anything, but I am just afraid that if it
indeed draws that much current, it will arc big time. Arcing can cause
hot bits of metal to spark off the connector and you don't want that
hitting your eyes.
Again, this is an unlikely scenario but better safe than sorry.

Tun the car a little while, just enough to slightly charge the battery.

Then shut it off.

Very quickly disconnect your battery and measure the voltage (quickly,
because we want to see if that battery retained a charge). It should be
12V or so. Even a bad battery may show 12V without any load on it.

Reconnect it.

If you see a nice big arc (you'll know what this looks like), an
appreciable amount of current is being drawn. That means something in
your car is not turning off, drawing a lot of current. The battery is
most likely not the primary problem. It may still need to be replaced
after you fix your problem because they do not like to be totally
discharged.

If you don't see an arc, nothing is being drawn so your battery is most
likely bad.

Report back with your findings.

Remco

Btw, in your case that clicking is most likely due to the battery's
voltage being too low.
You turn the key, the relay clicks on, the starter draws current
bringing the voltage even lower causing the relay to unclick. The
current draw drops causing the voltage to rise, the relay clicks, etc,
etc.

Your starter is most likely just fine.

Have you ever seen a battery blow up? I have and just in this situation.
With the lack of knowledge shown take it to a mechanic who knows what he is
doing and have it repaired correctly. Battery acid in the face is not
pleasant and pulling a cable while it drawing excessive current will do just
that. Gas is generated and the spark will cause to explode. ....

Thanks everyone for the help. I jumped the car and took it over to an
AutoZone. They ran a test and the battery did come up bad this go
around. Previously, I had the battery tested at a Walmart and an
O'Reilly and both times the battery came up fine. But after testing it
myslef today based on advice from here it did seem that the voltage was
low. At any rate, after I put in the new battery it started right up.
However, I've replaced the battery before in this car <never with a new
one> and evnetually it would fail me. So, this battery is brand new
and I will keep an eye on the problem and let you all know if I have
continued problems.

Thanks again for everyone's help. Time now to head back up to college.

-Jason

Your starter -could- have eroded contacts inside the solenoid.
Some Honda starters solenoids can be replaced,others(Denso) require
replacing the entire starter,or replacing the contacts.
(www.nationsauto.com is where I got the contact parts kit I used on my
Integra Denso starter)
