Car Forum / Nissan / Nissan Cars / October 2006Altima Battery and brake light - bad luck for me
Hello again, Still not solved my fisrt pb (tranny that locks occasionally on the 1st gear), i experience a second one that looks more serious. How it happened : I stopped my car and restarded and the 2 red light came on, they don't have disapeared until now. I read the old threads about those 2 lights in cunjunction, and checked the alternator: Battery voltage engine stopped, everything off, 12.6V Battery voltage engine running, everything off, 14,3V at 1000RPM or so Battery voltage engine running, everything on (road lights, radio, AC,...), 12V or so at 600- 1000RPM or so Battery voltage engine running, everything on (road lights, radio, AC,...), 13.3V or so at 2000-3000 RPM or so >From what i have read,those figures look ok to me, Can i take the car to do 600 km this we (those red lights make me nervous) ? Your help would be greatly appreciated, many thanks in advance, Luc. > Hello again, > [quoted text clipped - 14 lines] > > >From what i have read,those figures look ok to me, Time for a new alternator. > Can i take the car to do 600 km this we (those red lights make me > nervous) ? > Your help would be greatly appreciated, many thanks in advance, > Luc. It is also what i thought first, but when i whecked for voltage on load everything looks ok to me (more than 13 volts). Or i missed something (for sur but what) ? It is also what i thought first, but when i whecked for voltage on load everything looks ok to me (more than 13 volts). Or i missed something (for sur but what) ? I bet 1 of your diodes are open, maybe 2. I think you can frive it for a while but it ain't gonna fix itself. Keep a voltmeter handy I remember a few years ago I kept a cigar lighter plugand meter in the car so I could moniter the battery voltage while driving Mike >It is also what i thought first, but when i whecked for voltage on load >everything looks ok to me (more than 13 volts). >Or i missed something (for sur but what) ? NIRAV !!! Good to see you ! I must apologize, for some reason I had you on my blocked senders list... don't know why ... please forgive me Nirav is exactly correct on this matter, replace the alternator with a factory OEM part or.... care to take this one Nirav ? > > Hello again, > > [quoted text clipped - 21 lines] > > Your help would be greatly appreciated, many thanks in advance, > > Luc. > NIRAV !!! > [quoted text clipped - 7 lines] > > care to take this one Nirav ? I'm been around :) not posting as frequently, but nevertheless around. I see you're not posting as often anymore :). The answer is replace it with an OEM part or make sure you keep a spare on in the trunk, and be sure to enter the local "how fast can you replace an alternator contest" because you'll get so good at swapping out non-OEM remans that you'll be able to do it with your eyes closed... etc. I think the point is clear. nisstech is correct- you will be replacing an aftermarket nissan alternator. but in my case the Autozone brand one lasted for over 5 yrs in my 91 sentra. plus it was replaced under their lifetime warranty. took about 25 minutes to swap out in my case, but i did have to replace the upper bracket- it had vibrated to pieces in the 5 yrs! as usual anecdotal evidence is not always good evidence, but since i am handy with a wrench i didnt mind saving over $100 on the cost of the alternator... YMMV!!! :) robbie >> NIRAV !!! >> [quoted text clipped - 16 lines] > out non-OEM remans that you'll be able to do it with your eyes > closed... etc. I think the point is clear. The end of the story, I did 700 km last w.e. I was nervous because of the warning lights on. So i stopped every 15 minutes to check the voltage with my multimeter. And it was ok to me. After 1.5 hours driving or so, by magic the lights turned off !!!! I was happy with that. The only thing i did was clean the inside of the alternator. Happy end... Guess i was wrong, it didfix itself !! LOL Mike >The end of the story, > [quoted text clipped - 10 lines] > >Happy end... >>The end of the story, >> [quoted text clipped - 10 lines] >> >>Happy end... That's good news..but I'm trying to picture how you cleaned the *inside* of an alternator? Yes, i have not explained very well. I took the alternator out of the car. And then i opened it to see if someting was wrong (10 bolts to remove or so). And then cleaned the brushes, there was quite some carbon powder inside that i removed, but everything else looked good to me. It turns ok and is not shorted. Then i reassembled it, it put it back in the car. That's it, I think this is a classical procedure to clean an alternator isn't it ? br, Luc. > > NIRAV !!! > > [quoted text clipped - 16 lines] > out non-OEM remans that you'll be able to do it with your eyes > closed... etc. I think the point is clear. I think I'm figuring out the OEM vs. non-OEM thing; tonight after work I get to replace the alternator on my 1995 Nissan Altima GXE for the 3rd time in 6 months (the first replacement lasted 5 months and my second lasted 1 month). I was driving along just fine on the way to work and got the brake & battery light on just as all of my gauge lights and headlights dimmed. Since it's happened before, I just kept going to work knowing that running just off of the battery I can go about 60 miles at 55mph. So, if you haven't sunk your money into a "lifetime warranty" non-OEM alternator, go straight for the OEM. On the bright side, I'm not a mechanic by any means, but I can swap out my alternator in about 45 minutes now, so I'll just keep dealing with the inconvenience because I'm too cheap to start over and pay $180 for an OEM when right now it only costs me my own free labor. :) <sni> > I'll just keep dealing with the inconvenience because > I'm too cheap to start over and pay $180 for an OEM when right now it > only costs me my own free labor. :) Scott, I got plenty of yard work and stuff aroud the house I need help with - since your labor is free - can you help me out Saturday AM? :) All jokes aside, I know what you mean by being in the hole already on the reman, but the day you get stranded somewhere, you'll regret not biting the bullet and getting the OEM replacement. Cheers, Nirav |
