Re: New altenator and battery car loses charge
Bad regulator, is about I can figure, I have gotten a bad alternator before also. I am not sure if it is in the alternater are not, Some cars have a seperate regulator mounted under the hood if that is the case follow the wires from your alternator to locate it, Hope this helped you

So you are buying junk parts, or you really dont have a Alternaor problem? Have the charging system checked out by a Qualified Reapair Shop NOT the guy at the parts store selling you these wonderful parts. They will want to verfiy that the Alternaotor and Battery are indeed good/bad and check all connections, terminals, and ground points. If these are all good , then they need to find out what is going on.
It sounds like you have a major compent shorted out somewhere. Some thing is causing a discharge. Therefore your altenator is not responding and the car is draining the battery. Is the circuit between the altenator and the battery broken?? Also, you may need to check all the chassis grounds. Sometimes all your problems can stem from just a bad ground.
if you can charge the battery and drive it for a while then sounds like the altenator has failed and is not re-charging the battery, good way to test is to charge the battery, start the car and turn the light on, if everything is dimm or the motor dies there is little to no charge voltage, and will require altenator work
lf you have replacement cable ends on your battery, check that wires are not corroded under the straps. Also check alternator ground (run a ground wire directly to the alt case) I have seen "lazy" regulators at times but this is very rare. Also make sure drivebelt is tight enough to prevent slipping. Has your battery been charged and load tested?
well for starters your altenator is bad because what it is dolinging is over charging the battery hence why it boiled off the water/acid in the battery. the regulater is intergrated into the altenator. there is not a short because numberone your car would not start and two your battery would explode. i never test a battery or altenator at a store like napa or Oreilly's because they are not mechanics ......they are parts guys. your altenator should charge the battery at no more than 14 volts and the average is 13.5 volts. you need to replace the altenator the reason why you are losing a charge is be cause as the car is running the battery is being discharged because the regulator is defective in the altenator. please rate this thanks
well Marie the reason your vehicle is acting this way is because even though you put new battery in you still have to have a viable altenator to run the vehicle. the battery is only used to start the vehicle and run the radio and lights and other accessories. while the vehicle is running the altenator is not only suppose to charge the battery but it is suppose to supply the amprage to energize and coolapse the coil to give the vehicle spark. a bad altenator while driving doesn't charge the battery it drains it . a quick check is to have the vehicle running and then remove the positive battery cable if it dies you know it's the altenator.... please rate this and good luck keep me posted
