99 olds alero 3.4 liter v6 starter not disenaging disconnected power wires nothing got it disconnected volt light came on battery drained charged battery took car off jack started car starter did not disenage
i tried a different starter, disconnected all power wire, and shimmed it too. plus when the starter does disenage(3-4times) a volt light comes on and the voltage does not rise over 11.83 volts on a rebuilt alternator putting out almost 15 volts.i tried a different starter, disconnected all power wire, and shimmed it too. plus when the starter does disenage(3-4times) a volt light comes on and the voltage does not rise over 11.83 volts on a rebuilt alternator putting out almost 15 volts.

WELL PROBLEM COULD BE BROKEN DAMAGED OVERRUNNING CLUTCH ASSEMBLY NOT ALLOWING DRIVE PINION GEAR TO DISENGAGE.OR BROKEN RETURN SPRING IN STARTER SOLENOID KEEP THE SHIFT LEVER DRIVE PINION GEAR ENGAGED.
STARTER SOLENOID COULD BE FAULTY. LOW VOLTAGE DROP COULD BE BAD GROUND CABLE OR BOTH BATTERY CABLES WORN CAUSING HIGH RESISTANCE IN THE STARTER CIRCUITSTARTER SOLENOID COULD BE FAULTY. LOW VOLTAGE DROP COULD BE BAD GROUND CABLE OR BOTH BATTERY CABLES WORN CAUSING HIGH RESISTANCE IN THE STARTER CIRCUIT

Have the battery tested if no good replace. Check for power at the starter cable and then while someone holds the key in the crank position check for power at the trigger wire of the starter. If you have power but no crank or click then you may have a bid starter or the engine is seized. If no power on the tarter little wire which comes from the ignition switch make sure you fuses and relay is good and that your ignition switch is working. If the battery tests good have your alternator checked as well.
A test for a battery drain in the vehicle is to place a test light between the battery positive terminal and the battery positive cable,with the cable disconnected from the battery.If the test light glows bright you do in fact have a power drain.Pull one fuse at a time until the test light goes dim or off and then you will know which circuit is draining the battery.If no fuse removal dims the light,then disconnect the alternator output wire to check for a bad diode draining the battery in the alternator.Do not open doors or trunk etc and cause a accidental drain masking the real drain.DO NOT try to use any accessory or start the car with test light connected.
Check for power at the switch wire when someone turns the key to start. I would say there is a break in the circuit of the thin wire between the starter & the ignition switch
1. disconnect the positive cable from the battery 2. press on the brake for 10 sec. to drain all the power out of the vehicles main computer 3. locate the starter and disconnect the positive wire from the starter motor 4. disconnect the ground wire from the starter motor 5. remove the 2 or 3 bolts that hold the starter in ( remember the starter only goes in one way ) 6. put in new starter 7. put in the bolts torque the bolts to 23 ft. pounds 8. replace the power to power bolt tighten up tight 9. replace the ground wire to the proper spot 10. return the positive battery wire to the proper spot 11. start the vehicle
the alternator will not die in one day unless there is a direct short causing diode or coil winding failure which would give signs of smell, melted wires. Disconnect battery and give full charge. what year is this? while vehicle is running you should be able to briefly disconnect positive battery post connection and vehicle will still run if alternator is good. For a new battery to die in one day, one of two things i think has happened. Either the batt is faulty from supplier,( not likely but i have seen it ) or there is a direct draw or grounding taking place whether its direct in the starter selonoid or a direct draw through accessories. Are you sure all switches are off ? Push switches (on interior lights) nothing like dome lights,delayed lights are staying on! Does vehicle start hard like it almost needs a jump. If it has to be (and it takes time). to find out what is drawing the power ( i am old school) disconnect positive power source on batt. 2) disconnect ignition power source on starter. 3) connect pos batt wire to starter, 4) touch positive cable to positive batt post and look for spark or contact. if this reacts then selonoid or starter motor is shorted drawing the current. Or if you have volt meter and know how to use it, this is good to. If checks good then hook ignition connection back on starter.(disconnect pos terminal on batt prior to re-connect) I think the battery is having the life sucked out of it by a short in the system ( A DRAW ) this could be a quick find or fix or this could take days to track down. alot of variables here to try to explain. but i would seek into the starter first as usually this drains the battery quickly .
Sounds like you have something else draining battery. Possibilities include the alternator. For starter cranking voltage place the positive lead of voltmeter on positive of battery and the negative on the other. Disable fuel, then crank for 15 seconds and read volts while cranking. This is your cranking voltage. For voltage drop on cables, place positive on battery positive and negative at battery cable on starter. Crank 15 seconds. This should be less than .5 volts. The same can be done with any cable or wire in the starting or charging circuit of a vehicle. Just place the positive on positive or negative on negative, with the other lead at the opposite end of the cable being tested. In charging diagnostics, you will get the charging system operating with the engine running while you do the readings. I suggest though, that you do a parasitic drain check. If you disconnect the positive cable of the battery and place a test light in series (one end to battery, the other to the cable), you should have a very dim light to no light. If the light is bright, you have a drain. Proceed by making sure everything is off and there are no dome or hood lights on. Start removing fuses one at a time until the light goes out or gets very dim. Replace each one after you check it to avoid having a pile of fuses to put back. Also disconnect the alternator wiring to eliminate this possibility. A fried regulator may feed voltage to the fields all night if it's shorted. This will drain both batteries in relatively short time.
check resistance in the wires to the starter if battery is fully charged it should work fine, put a volt meter on the battery and see what the voltage is. from the positive on the battery to the positive on the starter. If you lose any voltage between these 2 points replace the wire.same on the ground side. do this while the car is being cranked. there should be no voltage drop until after the starter. many people account this kind of problem to the starter when in the first place it was a wiring issue in the beginning.
On a service parts identification label on the spare tire cover, look for a 3 digit code that starts with M, I.E. MD9 or some such, that will narrow down which transmission you have.
