Hi guys
got the red battery light come one , has a voltmeter handy in the cigarette lighter and was showing 11-12v
starter the car a few times before I got home.
I also had a few noises that were hard to track .
removed the belt and alt and tried to start the car to run without belt and alt and car now does not even turn over ???
what can this be?
thanks guys

To start with, what car is this that you're talking about? Your signature doesn't list a GL. But, assuming you are talking about "some" GL...
Second, it's a little tough to understand what you're saying. Can you re-word this (especially the bolded part): "got the red battery light come one , has a voltmeter handy in the cigarette lighter and was showing 11-12v

Was the 11V to 12V with the engine running or engine off? Either way, it's way too low. Double check with the volt "gauge" you can access through the center display.
What happens if you re-connect the alternator?
All that said (trying to weed through things here)... charge your battery and get it load tested. Even at 12V with the engine NOT running, it's way too low. Lot's of strange things can happen when a battery isn't up to snuff.

Sorry for not being clear
as the car was running was getting 11-12v.
charged the battery it is now at 12.4 with engine off.
the alt is off the car , and car will not turn over . Is this normal with alt off the car?

OK, with the engine running it should obviously be higher. Upper 13's to low 14's. I don't know if it's normal for this engine to not start with the alt not wired in - what I was saying was, try wiring it back in, even temporarily without actually mounting it, and see if it allows the engine to crank. That should answer the question.
12.4 is still pretty much at the end of it's life.

This is the latest
all started Friday when I came back from a 2 week vacation.
started the car and heard a whining noise from the belt
then 2 min later the red battery light came on , went to diag mode and saw 11v so I figured the alt was bad . Did a few stops on the way home always with the red warning.
got home and removed the alternator . Tried to start the car and key turns but nothing happens . Just put the new alt on with a full new battery and till nothing.scanned with my star and get codes for glow plug module and shifter module
they both won’t go away. Now also get message car not in P close door and drive to dealer no shifting .
I can sometimes put it in neutral but not always . Can this be front sam related or something else
all fuses are good
also when I turn ignition the voltage does not drop
thanks guys

removing the alternator should not affect the ability to crank the engine.
as mentioned, i believe your battery needs to be load tested as it is probably dead and has an internal short between the cells which might manifest with so-so voltage at rest (12.x), but will fall flat on face when loaded up with the starter spinning.

You mentioned you just put a new battery in. Double check that it's healthy with good voltage (should be about 12.8V at rest) and even load test it, just to be sure. Also, check that you installed it correctly and connections are tight. Low voltage can cause all kinds of gremlins.
Voltage won't (significantly) drop when you try to start the car if the starter doesn't kick in.

just installed the new alternator and the car is back to normal
crazy. A bad alt won’t let the car start

But... you stated above you already put the new alternator on and it didn't work. What's going on here?Originally Posted by ertech;7584513[b

Sorry my English is terrible
I put the old alt on before the new one arrived and it did not start
the new one fixes all.
Thanks all of you

Ah, OK, I got it. You tried putting the OLD alternator back on again. I'll be curious to here Alx's take on this - if he has happened to have heard of this, before.
