Question about 1988 Toyota Cressida

1 Answer

I RECENTLY REPLACED THE ALTERNATOR WITH A REBUILT UNIT. A MONTH OR SO LATER THE ALTERNATOR AND EMERGENCY BRAKE WARNING LIGHT CAME ON AND WOULD COME ON AND GO OFF. AT AN IDLE THEY WOULD COME ON AND EVENTUALLY SEEMED TO STAY ON. I DISCONNECTED THE POSITIVE BATTERY CABLE AND THE ENGINE STAYED RUNNING. ANY SUGGESTIONS?

1 of the diodes may be out in that alternater. It will still put out enough power (1/2 of what it should) to keep the car running but you will have problems while driving it at night with the headlights on. I would have it checked. My last rebuilt only lasted me about a month. Its hit or miss with those rebuilds.

1991 geo prizm, battery light and brake light in the dash stay lit when you start the car. The car still runs fine just the dash warning lights stay on. The alternator was replaced maybe three years ago,...


Yes, it could be. Or you can check your battery. And try adding brake fluid to your master cylinder. That sometimes will cause the brake light to come on. Or check your emergency brake. Hope this helps, James Booth.

Going through alternators


Hi there, I am a girl (i.e. not car savvy), but I have a 1998 Altima as well, and the first time (4 months ago) I noticed the brake and battery lights on simultaneously, I took it to a Nissan service shop. Everything seemed fine until about a month ago when the symptoms returned. I ignored the problem for 3 days and the car just stopped running, period. Took it back to the shop, figured out it was a fauly alternator, got it sorted, no problem. Today (1 month after replacement), I see the same bloody problem, and I'm taking it back to the shop in the morning. I am wondering... is it the alternator, or something connected to the alternator that is malfunctioning? The 2 alternators put in were "rebuilt" since they didn't have genuine Nissan alternators available. I really hope the dealers aren't taking me for a merry ride.

Battery not charging warning light showing


mcdevito75 here, The replaced alternator should have a warrantee, bring it back to the shop that replaced it. If you did the work yourself and even if it's a rebuilt, you should still be able to exchange it. Some manufactureres recommend a new alternator and not rebuilt, plus if you"ve added any moe electrical items you"ll need a stromger alternator (higher amp).

Brake failure urgent , abs light, low battery


So many lame responses...I went through this same experience and can tell you in my case it was the alternator. All of the warning lights such as the ABS light, airbag light, the warning about the brakes are all because the alternator is not providing the DC voltage all of the car's sophisticated electronics need to correctly monitor these subsystems' status. Mine left me high and dry by the side of Interstate 5 needing a tow. The low battery warning was off and on for about an hour before all of the other warning lights came on, and then about 5 minutes later every needle on the dash went to zero and the car died. After sitting waiting for the tow, it did start up again, but we got it towed to a dealer (thank god it got us within 8 miles of a dealer! the first warnings started when we were in the sticks) who diagnosed it as an alternator. $1200 and two days later and all is well again.

Emergency brake light and battery light coming on while driving


Check your alternator, if you recently had it replaced - make sure that the one you got is correct, if your working on your own.. take a volt meter, set it to dc volts and measure across the battery while the car is running, generally you see around 14 volts, 12+ volts from the battery always and the alternator adds around 2 while running - the weird smell you smell if it smells like a dying rat, it would sound like you will need an alternator - as for your brakes, I'd start by checking the parking brake lever - back to your battery light, make sure all connectors are good on the alternator and also if your alternator does measure 14 volts, turn on all acessories - wipers headlights, radio, blower, rear defogger - this will generate what we call a load, if you then go to your battery you should see the battery voltage not drop below around 13.5 if it does, you probably need an alternator because it's failing to meet the demands of your car. though the lights come on together, it doesn't necessarily mean their in the same circuit - I had the exact same problem with a nissan altima of that year, that came into the shop... all its bulbs were burnt out and it kept having that happen, then other times it was just fine! give that a try, if that doesn't work send me an email at senaelen@hotmail.com I'd be glad to give you advice!
