Check the charging system first. With the car running use a multimeter to see output of the alternator at the battery. Should be 13.5 + volts if the battery is not at 100% charge. If the guage is right and the voltage drops off check to be sure you have power to the back of the alternator. It's possible you may have a alternator problem or if it's externally regulated(I think it might be) a voltage regulator problem.
where is the computer hook up on a 1995 300zx <<<<<<<<<<>>>>>>>>> LOOK UNDER THE DASH ON THE DRIVERS SIDE ABOUT WHERE THE LEFT KNEE WOULD BE.
sound like you have a bad alternator. it will kill the battery.
The alternator when the engine is on, and the battery when the engine is off.
Before we go any further, have the battery tested at, Auto Zone, it's free, or wherever, to see if it will hold a charge. If it is good, start looking at the alternator, or something possibly grounded pulling the current, causing voltage lose.
Remove the battery cables and clean the connections, then clean the battery posts. Charge the battery by using a plug in charger, or jump the battery for about 5 minutes. Your battery may be putting out enough juice to run lights and accessories, but not enough to turn the engine over.
The fuse box.
as soon as you open the hood look where the battery is there is a little fuse box to the left and should be just under the battery. as soon as you open up the box its the first spot all the way to the left.
Your alternator has failed, and the battery has drained from running the vehicle without being able to recharge it. Replace the alternator and the battery should be fine.
it is located behind the pass side kick panel behind the main computer
The negative cable is attached to ground. On some cars is attached to the frame and on some it is attached to the engine.
Hey, I had the same probelm with my 84 300zx turbo. The fuel fitler is locates on the far left side of the car under the hood. Just look at your battery and it should be right in front of it. Hope this helps
