No crank when turning the key. Battery is at 12.23 Volts across the battery terminals.

I have the battery charger hooked up to it right now and the battery is pulling in 6 Amps. If the battery was fully charged, it wouldn't be pulling any current, correct ?

The battery normally has 14.7 Volts when the engine is running.

Is 12.23 Volts not enough to turn the engine over ?

That should be enough to start. The voltage may go away under load though. Or it could be a bad connection somewhere between the battery and the starter (on either the power or the ground side).

Measure at the starter (big wire to the battery to starter ground), while someone turns the key. The voltage should stay up around 12. Then check the small wire at the starter to starter ground. It should become live when the key is turned. If both of those pass, the starter is probably bad.

Maybe but I wonder about it buddy. It is definitely hurting at 12.2. I know my Ford Fusion had trouble starting at that voltage. It would start and then not start... Battery had 66k miles worth of starts on it. Replaced it and it was done after that. And yeah it is pulling those amps it is certainly down on charge. How old is the battery man??

Evidently. 12.7 is 100% I would give it at least 1/2 an hour.

My lady had a friend who was going on vacation and I just checked her open battery voltage. It was 12.45. Their vehicle did not start three times on that trip... I had a feeling that the battery was shaky. It was 6 yrs old.

Is your starter relay getting power? Easy check to see if it's upstream or down stream

I just replaced the battery in my mom's car as it was 5 years old and was getting harder to start. Didn't want her to get stranded and for $100 it was a wise decision.

Turn the headlights on, turn key, lights go out or stay bright? Lights out? Bad battery or connection. Lights stay on, don't dim? Starter not being engaged, bad starter solenoid, bad neutral safety switch, or bad ignition switch. This check works 99% of the time.

Yes, check for voltage at the big terminal, and the little terminal while someone holds the key in 'Start'
If they are both at battery voltage, then the starter is bad.

Sometimes, like 90% of the time, tapping the starter with a hammer will make it work again. But thats a 'get it home' or 'get it to the mechanics' without a tow bill trick.

Very very good post oldhp.

And Mr. Nice that is a very good way to go. That's the way I do that as well.

Try moving the shifter to neutral. It's always worth a try.

Load test the battery.
Voltage test is non-conclusive in terms of battery health.

If you don't have the load tester, part store will be happy to help you.

If you have a nearby Harbor Freight, spending $20 will help you diagnose the battery issue in the future also.

Check the battery voltage when it has a load applied to it. Turn on the head-lights, and interior lights and check the battery voltage with that load on it. It should be above 11.0 Volts.

If you have someone to help you, read the battery voltage while someone turns the key to start.


Boy will I be happy when ALL vehicles on public roads are autonomous.

All is well now fellas. Thanks for all your replies. smile

Apparently, 12.23 Volts is not enough to turn the engine over -- but 13.85 Volts is.

After startup, the battery was back to 14.5 Volts with a little jolt from the alternator.

Earlier today, I put the car in neutral so that I could roll the car out of the garage for cleaning the garage. I must've either left something on, or didn't put the ignition tumbler back to the full off position.

You more than likely need a new battery. How old is it?
