Won't turn over Battery ok

[StuntMan]

Tried to start up my 4.6 and won't even turn over. The battery indicator is green. So I'm stumped why the starter won't turn. All that happened is all lights on dashboard goes out and click.

Those built-in hydrometers are only showing the charge of one cell. So they are basically useless. If you have a voltmeter read the battery voltage at the posts then at the terminal clamps. They should be at least 12.4v for a battery at 75% of charge.

Might be a bad connection. Are the terminals tight and clean of corrosion?

FYI - a bad connection will show up as a drop in voltage for those of us that use meters.
For those that don't have meters, these connections need to be clean and tight. This is also one place you don't want to use dielectric grease.

Update: I got an attempted jump start. Still the same problem and tried bridging the solenoid with a screw screw driver, and still won't start.

If you have bad connections it doesn't matter how much battery is there. The power needs to get to and from the load.
Meter time and you can try hitting the starter body with a hammer. One good solid whack.

I'm going to assume that the "no start" is the engine isn't turning/cranking.

Yes soon as turn the ignition key one "click" and all dashboard and hood light go out. As soon as release the ignition key. Those lights come back on.

Meter time. A half way decent one will run you about $25-50, doesn't have the safety features of the better meters. Ok to use on low voltages but can burn or kill you on higher voltages should you make a mistake taking measurements.

Starter might be shorting internally if the lights go dim.

I'll take a shot...How old is this battery?

It amazes me how many guys reason "... It can't be the battery. This one was brand new when I installed it seven years ago."

Are u sure its in park

Less than 4 months old.

Yes I'm 100% sure.

Use the advanced search function for "PATS" and look for a thread that best describes the condition you are experiencing.

Pretty sure pats doesn't kill the starter circuit. Takes the injectors off line and may kill the fuel pump.

If the lights are going dim on the dash when he tries to crank it, something is pulling amps from the battery.

 

[stamp11127]

Agreed. He hasn't posted any info on voltage at different points so we don't know what voltage is at the starter. Therefore we can't approximate the amp draw. Some assumptions are being made, such as charged battery, clean connections, cables in good shape etc.

This has the symptoms of a stuck or shorted starter. He should verify that he is getting battery voltage at the hot lug on the starter. A whack with a hammer doesn't hurt either.

There is one other scenario that would have the same symptoms - a seized engine. For giggles check the oil level and make sure that it isn't the problem.

Try to start it in Neutral

The shifters on these expeditions get tempermental and worn out and u said your battery is good

Agreed.

Searching "PATS" lists many threads with conditions similar to those described by the OP. Solutions that are found there (PATS related or otherwise) might help steer the guy to a fix. Worth a look.
