Your problem is you blew a fusible link. Located in a black box in front of the battery are the fusible links. The one lablled battery is blown. The fusible link is a loop of insulated wire that will melt in cases where too much current is passing throught the wire. You will notice a burnt smell as well. A simple continuity test of the fusible link will show that it is open. Go to a junk yard or order through nissan and you will be good to go. If you make your own make sure of the type of wire and the gauge.

Battery will not help. You likely blew the rectifier in the alternator. (*And maybe a few other things as well.*) That's why it will start and run, but the alternator is pushing 0 volts/amps. Start with replacing this, and then go on down the line...such as bulbs, headlamp motors etc, that remain non-functional after you replace the alternator. Also, you will likely want to check the voltage regulator, and make sure that didn't blow as well. (*This item directly affects what your alternator outputs.*)

05 gmc envoy denali car was running replaced old batt now car wont start


Hey Stephen,,does the car turn over or is it completely dead?

If the engine, lights, horn don't work it your new battery.
Test or have tested, your new batteries charge and its performance
under load.

If the battery is okay and all the connections are tight and secure
and still no start..provide some more info on the no start vs no crank
question. Does the engine turn over?

Your owners manual might also provide some notes on changing the battery.

This van has the anti-theift component.....we go to town to the store lock it, go shopping we we re-enter the van it wont start a mechanic said it was the main computer gone bad what do you say?


i say the antitheft system probably was triggered when that happens it either wont let the vehicle start at all or it"ll start bt only run for 2 seconds try putting the key in and turning it to on and leaving it for ten to fifteen min if that dont work try reseting the computer by leaving the key in the ignition in the on position and first unhooking the neg battery cable then the pos cable then hold down breaks or horn to drain remaining charge all vehicles store even after battery is unhooked and leaving it for 15 to 20 min then take the key out and hook the battery back up and try an start it

I jumped car off it crunk on its own fora day,then batt went dead again,this time it won't jump off. It wants to crank but won't turn over.


not sure what you said but.
seems the battery is discharging,? 12.6v is fully charged,
own a voltmeter?
try a good loaned battery , does it start the car,?
i think you meant?
i can jumper cable start my car at any time. (off another running car)
but after running my car, the battery discharges and it will not crank at all. right?
this means ,the charging system on your car is bad.
if the starter cranks great, then the engine is flooded or is in great need of a tune up (sparkplugs etc)
if flooded try the super secret in the op guide, crank with throttle wide open , this magic trick cuts all fuel injection allowing the flooding
to purge away, and eventual starting.
my guess 2 is the car wont start, so you crank the battery flat
you jumper start it and it runs. (luck)
then day 2, same deal cranks ok but wont start.. ever tune up the engine?

Yellow security is light flashing, battery is charged, hazard light fuse isn't located under the hood for my1990 300zx won't start


If the security light is on then the car thinks someone is trying to steal it. If you can’t make the remote work then you might be able to clear it by disconnecting the Negative battery cable for about 10 minuets
