Charging system failed. Why is new alternator output ranging between 11 1/2 and 12 1/2 volts?

11 1/2 to 12 1/2 is not charging . That's less then battery state of charge , Battery stat of charge should be 12.6 volts , when charging with a volt meter you should see 13.1 to 14.1 volt at the battery posts . Is there a battery symbol lit on your instrument cluster ? Is there battery B+ voltage at the wires hooked to the alternator How to Test an Alternator

What is a rectifier block 2000 gmc sonoma

The belt could be slipping. Is the thick red wire hooked up at the alternator it should run from the alternator to the battery. Check voltage at the stud where the thick wire comes off the alternator if its not reading high 13's or low 14 volts your alternator is bad. I've gotten multiple brand new rebuilt alternators that were bad from the get go.

I have a draw on the battery on my 85 Toyota pickup it kills a fully charged battery in about 2 hours... Ive put a volt tester between the disconnected positive battery cable and the positive battery post...

Go to You Tube Video & see how to do a parasitic CURRENT
drain test

What you have done so far with a test light & volt meter is basically
doing nothing

You need an amp meter & a wiring diagram,then pull fuses one
at a time, to get to the circuit that causes the drain,then use the
prints to test that circuit for voltage drops

I have an 83 siverado 305 I have changed the alternator and the battery both are new and have been checked by autozone , the starter is only about 3 months old and i am still showing low volts below 1

if you think alternator is putting out the proper voltage. then check the post on alternator for voltage. its a possibility, that the wire is bad ! coming from alt, to battery and starter. if vehicle is running, there should be at least 13.6 volts to14.2 at battery posts. the higher is better. its also another possibility that the fuseable link in wire has blown ! that goes to battery. good-day !

Ive already put a new altinater and a brand new battery in my cutlass. it will start when i give it a jump from another car but then as soon as i try to drive it it dies on me.. and ive also cleaned the...

New battery and new alternator,you are looking for a open fusable link,If all are good you maynot be looking at a charging system, start the vehicle at idle, leave it running turn on the light and use the battery gauge on the car and turn the lights step on the brakes (vehicle in park) does it stall then, If it does then you are looking at a charging system can you exhange the battery and can you get the alternator tested from an outside source or better yet uses a voltmeter and read the charging system the battery at charging will need to be 2 volts above battery

Battery indicator light is on,replaced alternator,had battery tested,belt is tight,what could cause this?

voltage regulator?
bad alternator - yes you may have gotten a bad one.
main fuse.
wiring - did you put all the wires back the right way?
test the battery in the car.
1. voltage at battery not running 10-12 volts
2. votage at battery car running 13-14 volts
if all is well - you may need to reset computer / replace computer.

Just dropped in a new die hard gold series battery. Everything was fine for a few days. Last nite, we were coming home from the movies, had to turn on the headlights and windshield wipers. Dash lights...

Sounds like a bad alternator if the other battery also died suddenly.... make sure all wires are connected correctly to the battery and alternator and if so take alternator off and take it to autozone so they can check if its good..... Also take battery back so they give you another but take it after you take the alternator because sometimes they give you attitude and won't honor warranty because it was a bad alternator top begin with.......

Vehicle: '97 Nissan PU, alternator

ok we have four connections at the alternator( black wire is ground) (white with blue positive direct from the battery)
and two wires connector in the regulator(yellow with black that goes to charge indicator the red light and goes to fuse 7 10a fuse block inside) the blue with yellow goes to fuse 65- 7.5a in the left fron engine comparment fuse box))#1 check for ground at the black wire= #2 check for positive at the white with blue wire (allwas with power) this wire is protected with 100a fuse is in the left front engine comparment fuse box,
remenber== check the 100a fuse
and the two fuses that protect the regulator.
when you turn the ignition switch to the on position power goes to the alternator by the yellow black wire and activate
the alternator to work.
