battery light and emergency brake light coming on and off

Hey everyone.. I have a 1989 toyota corolla. The battery light and
emergency brake light coming on and off together.. as of late on all
the time. They sometimes go off but usually at higher speeds which is
wierd. Battery levels are fine. Had the cd deck cut out on me a couple
times while driving.. left it off for a while and waited and then it
worked again . Does this mean for sure its the alternator not charging
or what? i did have a 800 watt amp and 12inch sub running right off
the batt but unplugged that too see if maybe it was just draining too
much.. no dice. Anyways some insight would be nice. Thanks in
advance for some advice.

First, how old is the battery? Have it tested somewhere you trust.

My guess is the alternator. Both lights coming on like that mena the
charge circuit is compromised somewhere. On two of the cars this happend
to me with, they both needed new alternator brushes. One had Solder-in
type, and one had Screw terminal type. You can get them at the dealer, the
hardware store, or parts stores. If you like the car, don't use the
hardware store type. They work, but don't last too long.

Remove the alternator from the car and unbolt it. It will come apart. Ask
Bruce (or was it BGM) how to put it together...there's a trick I didn't
know about 3 years ago and have forgotten already!

Also, may want to replace the bearings at the same time. Brushes are $6-18
depending where you get them, and bearings are $15-22. It's pretty
straightforward.

Of course, you could buy a rebuilt one, but DON'T get the cheapest one you
can...I only like doing a job once every 5-10 years...not every 5-10 days...


Good Luck!

==================
Most likely alternator brushes worn.
Try replacing brushes and holder as a set from the dealer for under
$20.
Should be part number 27370-35060, or similar for your year.

Well thanks for the advice. Im going to test the battery tommorow with
a volt meter though the levels in it seem full. The batt came with the
car but it looks quite new. Have found a used one for 45$ with a 3
month warranty too replace this alt if its the problem..better then
messin around with the brushes and all that jazz...will let ya know
what the prob is when i do.. thanks

You'll probably see 12V. My Mom's Camry lit the lights, blew the horn, but
would not start. It has to have current, too. Bring it to someplace like
AutoZone and test it. Better test than a voltmeter.

And a battery with only 8 volts will start a car if there's enough current.

To do it right you need to upgrade your cars electrical/charging system for
the extra load of that high power audio system.

Definitely alternator related, my celica did the same when its diode pack
blew. 800W amp shouldnt be an issue though, fairly limited load.

I run two or three amps in my cars with no ill effects. No special "DNL's,
no capacitors, etc etc. I suppose if you have a 1000W amp running 3 12"
subs a cap might provide some holdup, but I just go for clean sound, not
to annoy the neighbors...too much! ;)

I wonder what the actual load is from say a 1000W audio system at low volume?

I bet its still 1 hp or so. hmmm

1HP = 746 watts. If a 1000W system was drawing 746 watts at low volume,
it would be drawing 54 amps at 13.8V. Highly unlikely.

Agreed, the only time youre amp will draw 1000W is during a long full deep
bass note which is fairly rare and short duration by nature, unless you
drive round with it on at a LOUD volume for long periods with a dicky
alternator I suspect you'll never have a problem with a good battery/alt.

Have your battery, and alt load tested. As for the brake light have
your fluids checked. IMHO, you should have already been in a shop,
rather than posting. Brakes are important. :D
