2001 cadillac deville

Deville 92 old. lots to find bad that old. !
here it is, ID #2 below
you were told wrong, the reg is inside the ALT, actual.
the internet lied again.; 1/2 the time, asking 8year kid same.

the top parts sellers online,shows, no REG outside, so strike 2 on reg outside.

learn to keep that old (how old is it?) battery charged fully until car runs perfectly. or it can take 1/2 to jump start it or worse. dead batteries do not start engines and overload the poor donor cars electrics, doing so.(jumped)

once battery is new, or charged or load tested in a real shop
start the engine, see if GEN/CHARGE lamp goes out.? on dash.
if not alt is bad. wow no fuse then, scary then. lots of car fires.
or use voltmeter idling, at bat terms. 13,to 15vdc good below ALt is dead
140amp alt here.

check for battery connection or starter relay for a short to ground or volt..

Electrical problems require tracing from where you have current to where you do not. For example, it could be dirty battery terminals, back chassis ground connection, missing engine ground strap, bad neutral safety switch, bad ignition switch, bad starter solenoid, bad starter field or armature brushes.
See if there is current at the starter solenoid, when you try to crank it, with a test light. They move further upstream if there is not.

Sometimes if the battery is really dead, even jumping it wont help it start up. It just sounds like a dead battery. Just try getting a new batter first then go from there.

starter getting hot, check the shield

If the battery checks out good then have your starter tested. This can be donr by completing a bench test. Dont forget to rate this!!

First, I would determine it is bad. I have a 1990 Cadillac Sedan Deville, and sometimes it doesn't turn over. But, if I toggle the switch a few times or up to 5 times, it starts to turn over and the car starts.

I have the same problem with a 1997 Cadillac Deville.

If you are set on changing it, here is a picture and instructions on how to test:
Starter TESTING Voltage Drop Test Fig. 1: Schematic of a voltage drop test
NOTE: The battery must be in good condition and fully charged prior to performing this test.

1. Disable the ignition system by unplugging the coil pack. Verify that the vehicle will not start.
2. Connect a voltmeter between the positive terminal of the battery and the starter B+ circuit.
3. Turn the ignition key to the START position and note the voltage on the meter.
4. If voltage reads 0.5 volts or more, there is high resistance in the starter cables or the cable ground, repair as necessary. If the voltage reading is ok proceed to the next step.
5. Connect a voltmeter between the positive terminal of the battery and the starter M circuit.
6. Turn the ignition key to the START position and note the voltage on the meter.
7. If voltage reads 0.5 volts or more, there is high resistance in the starter. Repair or replace the starter as necessary. NOTE: Many automotive parts stores have starter bench testers available for use by customers. A starter bench test is the most definitive way to determine the condition of your starter.

Remember to disconnect the battery and remove the wires from the starter at the hex nut.

Then, remove the 3 or so bolts that hold the starter on using an extension and ratchet if necessary.

Hope this helps.

IT SOUNDS LIKE THE BATTERY NEEDS MORE JUICE TO TURN THE STARTER. HAVE IT CHARGED. AND THEN HAVE THE ALTERNATOR TESTED AT YOUR LOCAL AUTO PARTS PLACE FOR FREE. PERHAPS THE ALTERNATOR IS NOT FUNCTIONING PROPERLY.I HOPE THIS HELPS. THANKS FOR USING FIX-YA.

it isnt making a good conection on the body ground
