SOURCE: replaced alternator on 1997 ford escort and battery indicator lig

Battery light is on and battery is not holding the charge because you have at lest one cell damaged
because of accidental short-circuits between the battery terminal. So most probably you need to get new one (in Sears starts from $49,99) For fuses location follow this link please
Good Luck

SOURCE: alternator is not charging the battery

You have fuses under hood, one should say "alt" I'd check that as well as in the vehicle also.

SOURCE: replaced alternator and battery is good but not charging

I found the problem YEAH. It was the fuse that is in the side of the fuse box under the hood, Its where the battery wire from the alternator connects thru a fuse to go to the battery, Its one hundred and something volt fuse. It took care of the problem instantly.... Thank you all for your replies...

1997 Lexus LS400 wiring problems when it's wet outside


Insure the drive belt is turning the alternator properly. When it is wet outside the belt will slip quite a bit more if it is not tensioned properly. Also ....the ground from the battery post to the engine block needs to be checked to insure a great connection. Any resistance in the ground cable OR the positive cable from the alternator to the positive post of the battery will cause your issue....dampness will make these issues worse.
Would check output of alternator when damp/wet outside...and find a tech that KNOWS how to perform a voltage drop test on the battery cables and the alternator output wire that goes back to the battery.

Hope this helps!

Have you checked the major fuses around the battery and underhood fuse box ?

My 1991 Lexas LS400: All of the dash icons light up and radio goes on/off (at the same time) when applying the brake and/or while the `car has stopped. Had new battery checked, the battery is good....


I've seen this before, the problem ended up being the brake light bulb lead contacts touching each other on the dual filament bulbs allowing back feed voltage to travel through the park/dimmer switch circuit causing the lights to activate while pressing the brake pedal. I would pull all the brake light bulbs out and look at the back of each one, if you see nothing unusual, I would still replace them all only because it could be internal to the bulbs as well. Let me know if this fixes your problem.
I hope this info helps!~subyguru~

There is a fuse in the fuse block under the hood on these cars that usally blows when the alt. craps out. try changing the fuse and then this should solve the problem, If not then look at the wires coming from the altinator and make shure none on them have been rubbing and have grounded themselves out.

You do need an alternator. Nissan has a campaign on Maxima alternator in certain years such as 96-98 I believe. Go to your friendly Nissan dealer abd have them punch your VIN number into the NNA net. they will know and that will tell them if your vehicle applies by the VIN. I have seen the alternator on fire. There was fire inside of the alternator. Have it checked or the car can catch on fire.

1997 Nissan Altima problem


Check your battery fuse mine just also did that and it was the fuse under the hood. Location of fuse box is by the battery and it should be the big fuse close to the middle
