If your truck is running fine and all of a sudden stops dead with no warning, check the alternator. drop the belt and see if the engine will turn. if it does, get the alternator checked. if the pulley is bad, the engine will cut out with no warning.

Alternator Problems, help!


First snug up belt to alternator. With engine running check voltage at battery...should be 13-14 volts. If not check connections...both battery connections, ground wires etc. Is battery good? Sounds like a short though.

SOUND LIKE A DEAD BATTERY BUT CHECK BATTERY VOLTAGE SHOULD BE 12.6 VOLTS.IF NOT BATTERY DEAD NEED TO BE CHECK AND REPLACE.MAKE SURE BATTERY CABLES TIGHT AND BATTERY CABLES AND BATTERY POST CLEAN FREE FROM CORROSSION.AFTER REPLACING BATTERY MAKE SURE ALTERNATOR IS CHARGING BATTERY. WITH ENGINE IDLING BATTERY VOLTAGE SHOULD READ 13.5 - 14.5 VOLTS. MEANS ALTERNATOR IS CHARGING BATTERY. IF NOT CHECK ALTERNATOR FUSE AND CHECK ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES, MAKE SURE WIRES NOT FRAYED OR BROKEN. IF ALL IS GOOD MAKE SURE ALTERNATOR DRIVE BELT TENSION CORRECT.MAKE DRIVE BELT TENSIONER NOT BROKEN OR DAMAGE CAUSING DRIVE BELT TO SLIP OR CHECK ALTERNATOR CHECK ALTERNATOR PIVOT BOLT MAKE SURE NOT LOOSEN CAUSING TOO MUCH SLACK IN DRIVE BELT CAUSING BELT TO SLIP.WARNING TURN OFF RADIO FIRST BEFORE REMOVING BATTERY CABLES TO REPLACE THE BATTERY BECAUSE IF RADIO WAS LEFT ON WHILE BATTERY WAS DEAD WHEN YOU INSTALL BATTERY CABLES THE POWER SURGE WILL DAMAGE RADIO.

97 nissan 2wd 4cyl.pick-up battery and brake warnihg lights on,


Got a 85 Nissan 720 4x4 with the 2.4 engine with Weber.Have them test the alternator after you take it off,also check your fusible links and your positive battery cable connected to starter and the negative battery cable that is grounded to engine.My truck has a volt meter telling me what the system is doing which normal is 14.5 volts while running,battery should read about 12.6 when not running,could also be that your alternator belt is loose,maybe change that while your at it.You can crank engine up,have hood open,rev engine up and watch belts turn to make sure they are not loose.I f you need,I can send you a free repair guide on your Nissan.Here's mine. 85 Nissan 720 4x4 Silverbullet 4 with Samantha YORKIE at the wheel look out

While driving, all warning lights on dash suddenly were lit. When I stopped the car, it wouldn't start again and sounded as though the battery was dead.


Probably the alternator died, then used up all the power in your battery to keep the car running.
Have your alternator tested and maybe replaced. The battery needs tested also.

Hope this helps
