Gauges don't work, battery goes dead, ignition changed, battery changed, alternator changed problems presists

Sounds like a charging system problem and the alternator may not be working. The gauge light will come on if the charging gauge is showing low so you will look at the gauges. Have the battery and charging system tested

When you say everything goes dead are we talking all lights, radio, wipers? If so, main power or ground cables bad or fusible link. If just engine, check coil, ignition module, crank/cam position sensor.

I would be getting the alternator checked out first, faulty relays are not something I have had problems with in the past, so I would go with the alternator, unless your battery is duff, don't forget a battery can be fine the last time you use the car and then it just goes dead. I would suggest you try a charged battery first and check when the engine is running that the ignition lights are all out, if not then change the alternator

SOUND LIKE ALTERNATOR FAILING.TURN OFF AC OR RADIO TAKE LOAD OFF THE ALTERNATOR UNTIL YOU CAN GET TO A REPAIR SHOP.

SOUND LIKE DEAD BATTERY.HAVE BATTERY CHECKED AND REPLACED.MAKE SURE ALTERNATOR CHARGING BATTERY.WITH ENGINE IDLING BATTERY VOLTAGE OUTPUT AT BATTERY SHOULD BE 13.5 - 14.5 VOLTS. IF NOT CHECK ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES FOR DAMAGE OR LOOSE CONNECTIONS,CHECK ALTERNATOR FUSE AND MAKE SURE ALTERNATOR DRIVE BELT NOT LOOSE SLIPPING OR BROKEN.

If it goes dead, it has to do with the charging system. Make sure the terminals are cleaned and they have good contact. You may need to redo them or may need new ones. Make sure all wires are correctly on, starter and alternator. Make sure the wires to both are not damaged. Make sure all wires are in the right spot. Make sure nothing is being left on to drain the battery. Make sure your alternator is good Steve. You can start the car and take off your hot side terminal. If the car dies instantly, change the alternator. If it stays on, you have a bad connection in the charging system more then likely. If you have any questions, just let me know.

You may have a bad battery or alternator, its best if you take in to the Auto parts store where you bought the Battery and Alternator to have them check it on your vehicle, they have tools to test the charging power from the alternator as well as to check the battery condition. Just because their new does not mean they are always going to work.

Your alternator may be on it's last leg. Start the car and while the car is running, remove the negative cable from the battery. If the car dies, the alternator is no longer working. If you have a volt meter, put the meter on the battery positive and negative. You should read 13.8 - 14.2. If it doesn't show this, and reads under that, your alternator is not charging enough to keep your accessories going.

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

on the alternator did you put the little washers where the regulator bolts on back of the alt they must be tight and also the ground cable from the battery to the alt bracket must be tight and grounded sounds like a loose connection
the washers go between the alternator and wires coming out of the harness and the alt also it probalbly goes dead occasionally when you crank it up
