My cheavvy tahoe batteries keep dying shortly after being put in


Battery failure on this scale, leads to suspect an overcharging fault with the alternator, continual over charging damages the plates in the battery leading to premature failure. Cold will effect the battery a little, but it should be able to cope. Connect a volt meter to the battery and see what the charge rate is. Engine running 2000 rpm, reading should be around 13.5 to 14.2 volts, if it is above 15.5 volts then it is damaging the battery. Hope that helps.

How to reset the battery dashboard warning light on chevy tahoe


a new battery will keep the volts up for a while. the light warns that there is a problem, usually its the alternator, one way to check is to loosen the positive battery cable, a little, start the car and disconnect the positive cable if the car dies the alternator is bad if it still runs its probably ok

My husband has a 2002 Tahoe and his battery light started flashing while on the highway. He turned everything off, A/C, Radio, etc. The battery meter is reading around 12 volts and he is on the highway...


Good idea to keep everything off. How far he will get depends upon the actual condition of the battery.
If it's the factory original, chances are it may not make it the full distance. If the battery has been replaced, and, it is in good condition, pretty good chance it will go that far. Watch the engine temperature though. If it isn't charging because the belt failed, it soon will be overheating too.

2002 mercury montaineer , battery light comes on , they gages shut down couple minutes after then the truck acts like it gonna shut off....when getting a jump, the truck fires right up, couple minutes...


Your battery is definitely low. First clean the terminals on the battery and the inside of the terminal rings on the wires. If you have a slow charger put it on that overnight and see if it holds a charge. If it still keeps depleting or doesn't charge overnight then either your battery or your alternator are done....possibly both. So take the battery to have it load tested. Most places that sell them can test them. If the battery is done replace it then test the battery with a volt meter. If the old battery is still good put it back in the vehicle and test the voltage with a volt meter. With the engine off the voltage should read 12 volts (once its fully charged or if its new) with the engine running it should read around 14 volts. If it is way higher than that or it doesn't go up at all your alternator requires replacing. Alternators are fairly easy to replace but if you don't feel comfortable with that take it in to a mechanic.

Engine light on. scanned and p1388 code. What is the meaning of this code?


P1338 - Fuel Pump feedback circuit low/high voltage. This is indicating that your fuel pump is either getting too much voltage or too little voltage as is sensed by the fuel pump control module. Now, this can be caused by either bad wiring connections or a battery not charging causing low voltage. Should read 14 1/2 volts if charging at 1500 rpms

I just had the oil changed in my 2002 Tahoe but the ''change engine oil'' light keeps coming on. How do I turn it off?


Turn the ignition to the on position so dash lights come on, but do not start. Now pump the accelerator pedal three times quickly. The light will go off for another 3,000 miles

Chevy tahoe won't turnover, power to everything, no clicking in starter to indicate that it is the starter, nothing happens when you turn the key? any sugg


have to make sure the starter is getting power. make sure the engine will turn over by putting a socket and ratchet on the crank bolt and turn it to the right. the two wires to the starter is battery the big one and the little one is for the ignition. ground test light check big wire, then have a friend key it up to check the little wire.
