It sounds like you have a circuit staying hot all the time, like a bad switch or even a radio. Also might have a defective new alternator or battery or both. Start with the most obvious places first. Hope this helps
It could be the voltage regulator.
It could be two things. As you know, the alternator charges the battery so it will not drain. If the alternator is not working properly to charge the battery, the battery will continuously drain. Have the alternator tested at your local Auto Parts store (NAPA or Advance Auto) If it is good, have the battery checked.
check to see if the alternator is working properly or maybe an alternator wire came loose with the new battery installation.
Not likely but as alterantor keeps trying to charge a weak battery it may wear out, however as you are not likely to keep a bad battery in the car for so long there should be no damage to alternator if battery is replaced.
English translation: "I have a 1997 Chevrolet Silverado. Keeps losing the battery charge, I've checked the alternator. Can someone help me?"
Sounds like the alternator is not charging the battery up / WORKING check charging system. Charge battery to 12.8 volts and then start engine and hook volt meter to battery and it should read 13.8 to 14.3 volts. If it don't then replace alternator. Also need to make sure the alternator belt is tight.
The battery "starts" the car...after that the alternator keeps the battery charged. They work together in other words.
Fully charge your battery then take off cables. If still charged after sitting unhooked overnight, then you have a short somewhere and need to take to an electrician. If the battery is dead after sitting unhooked, buy a new battery.
Believe it or not. ADD COOLANT>
I'm assuming its a riding lawn mower of some type. Our own lawn mowers of this type have an alternator in them that keeps the battery charged
The battery will run down and he engine will stop. You will not be able to start the engine. The alternator keeps the battery fully charged.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
