Question about 1989 Ford Tempo

    I have the same problem with my 1989 Ford Tempo. I was driving home last night and noticed the battery light had come on. I am wondering if it is just the altenator, can I just replace the brushes or am I in for a major repair? Is it more economical to just trade the altenator for a rebuilt. Any other suggestions would be very grateful.

Check with a test light, Power on the main post. Then unplug the three pin connector, you need to test for power to the regulator. I think the wire is green/red. It's not the white wire. The green/red wire is fed from the alt fuse in the underhood fuse box. The white wire is just a jumper wire to the one pin connector next to the three pin. The other wire goes to the light. If one of the pins in the Three pin connector( like i said i think its the green wire) and the main stud both show power, the take the alternator back and get another one.

There are two bolts holding it on the mounting bracket. They are long 7 or 8 inch bolts. Remove these and disconnect the wires from it then pry it up between the alternator and the mount. It sounds more like a coil or plug wire problem to me as far as the now start when wet. But you definately have a battery drain issue.

What does it mean when the battery light comes on? Is this the battery or alternator?


99 percent of the time it does mean a charging problem such as the alternator. There is a place that you can look to see is a fuse is blown that would cause this in you car. It is in the fuse panel located in the engine compartment (see picture below) and it is a 30 amp mini fuse and is located in the number 26 position in the fuse panel (see other picture for layout diagram). This is for the generator and would cause you not to charge as well as make the battery light come on. It may be the alternator but I would check this first. I hope this helps you and good luck.

Hello and welcome to FixYa! If the battery light is on, I strongly suggest that you havethe battery charged. It can be an indication of a weak battery or a faultyalternator. If the battery light still on after charging then the problem willsurely be on the alternator itself. If that's the case the alternator should bereplaced to resolve the problem. If the battery won't hold charge even on a new alternatorthen the problem will be on the battery itself. It surely is in the end of it'sservice life and replacement will be necessary. You may try to reset it to by removing the positive batteryconnector, letting it sit for at least 5mins. then reconnect it again. Thiswill reset the system and can get the battery light off. Hope this helps and thank you for using FixYa! Have a goodone!

Battery light comes on when accelerating, alternator is ok


In fact the Alternator is on it's way out, I had Taurus that was doing the same thing. When the RPM's were over 3000 the light would flicker. What happens is, the slip rings wear and get out of round and when the RPM's get too high the brushes start to bounce causing the light to flicker. Keep in mind the alternator is spinning about 3 times the speed of the engine. Pick up an alternator it's just a matter of time, mine went about 6 months like that, try to keep the RPM's low.

2004 Taurus. Will not start at intermittent


I have the same car but don't have that problem with this one however, I did with the 99 I traded for this one. I figured out that if the wheels were not left straight, any degree of angle facing either direction, would freeze something in the steering column and not allow it to start. Had it towed twice before the tech said he had the same problem in the past. Never happened after that. The prob I had with the 2004 Taurus, bought a cheap battery from wal-mart and it ran everything but my car, tech said it's probably the reason the alternator had failed. Check your brand of battery. My battery light stayed on for two months, started fine, switched the battery from the wal-mart one, light went off instantly.

99 taurus won't start,power windows,locks


CHARGING CIRCUIT NOT WORKING PROBABLY ---CHECK THE BATTERY CONNECTIONS FIRST
THEN NOTHING ON OR W NEG CABLE DISCONNECTED CHECK THE aLTERNATOR WIRE CONNECTION
OR THE COIL MAY BE WORKING IMPROPERLY TOO
OR YOU GOT A BATTERY WITH WHAT'S CALLED A DEAD CELL--BRAND NEW
IT HAPPENS ---IF YOU GOT IT AT AN AUTOPARTS STORE OR CAN GET TO A aUTOZONE OR
aDVANCE AUTO --they should be able to test it all if you don't have a volt meter with a dc setting
there is a way to field test the alternator easily --but you need the volt meter --one red lead goes to a Grounding cut on --small in the back of the alternator and the black to a good ground I use the battery neg or a bolt on the engine accessory bractets ---you insert the red lead probe into the
ground plane slot --while cranking needs to exceed 13volts to considered charging
or you can use a Clamp on meter on the positive wire coming from the alternator too
I have the 97 SHO ---3.4 v8 ---now that's a hand full
I did have a 99 merc mystique albeit identical to yours though
My SHO alarm system will slowly drain off the battery to when left parked for a week
probably a short to ground or slow draw bleed off ---I haven't even tried to track it yet
I leave it parked --due to law enforcement harassement and I've had a clean license forever
just can't drive to or from without being harassed and it's 100%stock
ford in 2010 launches the 365hp twin turbo ecotec V6 with all wheel drive ---but I already know
ford techs --won't fix them right when things go wrong and they will --heck they won't change
the oil in a late model sho v8 ---"Not Qualified" or 'Not allowed to per ford corp mandate sorry"
No Dealer service available to date --I've been to 27 dealers for service when traveling =no dice
had to go to Lexus for an oil change --Kudos to Lexus

99 Taurus dies quickly and random windshield wipers


Its sounding like you have an electrical short in the car. These are the hardest things to track down. Basically the home test you can do is with a basic test light. Disconect your possative lead from your battery and *short* the conection with your test light. Clip on the clamp touch the point to the posative battery terminal. With the car off it that light comes on super bright you have a short to start tracking down.
