MJBBMANO Posted April 4, 2008 Share Posted April 4, 2008 I was driving home today and while the truck was moving the Battery light and Brake light came on. It only did it once and I turned the A/C and radio off. I waited 2 mins and turned the A/C & radio back on. It didn't happen again. Hopefully it won't happen tomorrow. Does anyone know why this could of happen? 1997 LE Thanks Link to comment Share on other sites More sharing options...

Simon Posted April 4, 2008 Share Posted April 4, 2008 Check the belt tension.....it could just be loose. Otherwise... X3 Link to comment Share on other sites More sharing options...
vengeful Posted April 4, 2008 Share Posted April 4, 2008 well, it could also be the voltage regulator, but thats integrated into your alternator and the whole alternator needs to be replaced to fix it. Time to upgrade to a quest! LOL Link to comment Share on other sites More sharing options...

Time to upgrade to a quest! LOL What are the chances that its the battery? I also had all the belts replaced in Feb/08. Could it still be the tension? The light came on last night on my drive home. As soon as I turned on the A/C. Link to comment Share on other sites More sharing options...

The light came on last night on my drive home. As soon as I turned on the A/C. A low battery won't trigger the warning lights to come on. In fact, you could technically remove the battery from the truck while the engine is running, and the truck would hardly notice the difference. Usually, when the alternator dies, 3 lights glow: BATT, BRAKE, A/T TEMP. The warning lights probably came on because the A/C draws extra current from the electrical system.

Do you think the test auto parts stores do are good? I know Advance discount auto test them. How much longer do you think I have before it dies? I spoke to the service dept at a Nissan dealer and he said that it might just be the ground. How do I check that? I was also told to check the connector to see ifit's dirty or loose. The dealer wants almost $500 parts & labor. Edited April 5, 2008 by MJBBMANO Link to comment Share on other sites More sharing options...

They are charging me $233 to remove, rebuild and install with a year warranty. Is that a good deal? Link to comment Share on other sites More sharing options...

Is that a good deal? I took the advice of the dealer and checked the connectors as he mentioned. After disconnecting and re connecting the connectors I haven't had the lights come on since Friday April 4. I took it yesterday to Advanced Auto parts and they tested it. The computer said theres nothing wrong with it. Any suggestions on what could have been the problem? Thank you all for your help. Link to comment Share on other sites More sharing options...

MJBBMANO Posted April 18, 2008 Author Share Posted April 18, 2008 bad connection My lights came on again. I'm currently having the ALT replaced. Is a Bosch ALT good? I know the bosch spark plugs didn't work in my truck. Link to comment Share on other sites More sharing options...
XPLORx4 Posted April 18, 2008 Share Posted April 18, 2008 I'm currently having the ALT replaced. Is a Bosch ALT good? It's a little late to ask now, isn't it? You should've selected the equivalent of a Nissan Quest alternator, which puts out 110 amps. The OEM Pathfinder alternator only puts out 90. Not sure what the rating is on the Bosch you're having installed. Oh well, maybe next time. Link to comment Share on other sites More sharing options...

Whats the differnce between a 90 & 110 besides the amps? please give me an example. like will it die quicker, not start right. I have the part number and will look up which one I have. I also had new brakes put in (ceramic). less brake dust cleaning...I hope. Thanks, Link to comment Share on other sites More sharing options...

The Quest alternator is more powerful, but if you don't run a bunch of electrical accessories, stereo, lights, winch, etc, then it's probably not necessary. Your truck (if your avatar is a recent pic) looks pretty stock. Link to comment Share on other sites More sharing options...

No upscale audio system. oh yeah I run my A/C a lot since I live in Florida. All items are plugged to a multiple outlet. Is that good for the ALT?

deej Posted October 1, 2008 Share Posted October 1, 2008 Looks like I'm due for a new alternator too. What years/engine Quest alternators will work? Are they the same as the Mercury Villager alternators? Link to comment Share on other sites More sharing options...
