Thanks for the heads up, saved me a lot of headache searching for a problem with wiring. changed my regulator on a remanned alternator with the old one, works perfect.
I noticed that the *Motorcraft* labelled voltage regulators -- the black ones -- have a 1995 part number ( 'F5' = "F" : 1990's ; "5" : 1995 ) , but I couldn't ascertain the aftermarket ( referred to as 'The Original' in your video ) regulator's number , nor could I ascertain it on the *Motorcraft* white coloured regulator . I have a 2004 Crown Vic P71 ( I bought it from a private party two weeks ago ) which has a replacement alternator . Everything was good until today ( 28 / 04 / 2021 ) . I noticed tonight ( 21:55 HRS ) that the 'battery' light was flickering intermittently . I'll have to scope out the voltage regulator tomorrow ; I'd be surprised if it's an OEM Motorcraft part ; and further surprised if it has a newer part number ( e.g. , "F8" or "XR" --- Fo. Mo. Co. part numbers changed in 1997 , with most parts carrying an "F7" prefix , whereas others carried an "WR" [ et al. , ad seq. ] prefix ; maybe even a "3R" [ 2003 ] ad seq. ) . Thanks for the pointers regarding this 'Gremlin' .
For the past of two weeks sense I have my 08 grand marquis that had an alternator's problem but I didn't go to the junkyard but I know the place who knows how to rebuild an alternators but they have alot different of alternators on a shelf who already rebuilt thank God they had mine on a shelf, and I gave them my old alternator with $105 but if they don't have mine on a shelf I have to be waiting for 2 hours but thank God my problem solved, but in auto parts they asked me $250 plus $30 for the core charge, I saved a lot of money, that place rebuild alternators, starters, generators, and jump starters.
It started out that my battery gage would drop near 0 and my battery light came on so went yesterday to get another alternator which seems to have made things worse because now with the new alternator all my dashlights are coming on and the battery gage on dash goes all the way high maxing out and it's doing this on & off on& off I've had problems in the past with putting new alternators on til we thought we finally found the right one but the last one we put on (new ) was only less than 2yrs old My question is with this new alternator why is all dashlights coming on & off battery gage maxing out like over charging and before we put new one on the alternator that was on it would just battery light on dash would come on and the gage would go very low an then would go back to where it should be but the car never failed to start if my gage showed nearly dead when I would come out from store car would start back everytime???????? HELP
Your car has a pcm belongs to white voltage regulators, grey or black voltage regulators are meant for non pcm fords year 2002 and below after 2003 panther cars started using pcms so the grey voltage regulators wont charge due to pcm
That's a decent rate. Batteries rest at 12.5 to 12.7. Good Systems will charge between 13.3 to 14.7. The more load you have the lower the voltage will be depending on the amp rating and the technology in it.
i had the same problem in my 2006 Grand Marquis GS after the ford dealer replaced the alternator after 2 yrs of it being in car i find out why my battery light kept comingon it was putting out 16.5 D.C. so my dad got me a new alternator & belt for it problem solved on mine
brandon laielli just that I used the white voltage regulator and the light didn't come back on. I considered it fixed. All the research I read was that you should buy a motorcraft alternator because it has the circuitry to properly communicate with the ecm and keep the light off. If going aftermarket, I'd look at the regulator and see what color it is.

I’m dealing with the same issue on a 2003 expedition ( battery light). The bad news is I don’t have any codes or my old alternator.
Me 2 smh abs brake lights cut on and everything stops working

You're $$$ ahead to buy a used OEM alternator($35) out of the yard with 119,000 miles vs a brand new aftermarket one for $171.
Great video
Freddy Hollingsworth I bought a brand spanking new alternator at Rock auto for $95
It started out that my battery gage would drop near 0 and my battery light came on so went yesterday to get another alternator which seems to have made things worse because now with the new alternator all my dashlights are coming on and the battery gage on dash goes all the way high maxing out and it's doing this on & off on& off I've had problems in the past with putting new alternators on til we thought we finally found the right one but the last one we put on (new ) was only less than 2yrs old My question is with this new alternator why is all dashlights coming on & off battery gage maxing out like over charging and before we put new one on the alternator that was on it would just battery light on dash would come on and the gage would go very low an then would go back to where it should be but the car never failed to start if my gage showed nearly dead when I would come out from store car would start back everytime????????

I have a 2011 grand marquis just bought a brand new alternator and the battery light came on . It’s a duralast
I'm having problems with my grand Mercury Marques alternator maybe you could help ?
I would question the Amp output
I have the same exact issue and I need to check numbers on the altenator

Cool. Thank you
It’s in the wiring connecting the battery to the alternator. Got that fixed and my light has been off ever since
What was wrong with the wiring? Corroded? Bad connection? Fusesble link?
What do you mean the wiring if I can ask
I’m not exactly sure what was wrong or what wire it was I’m not a car expert, the person that was working on my car told me that
My grand marquis 2001 charging 13,1 with ac on and 13,3 with ac off when i started morning charging 13,5??
That's a decent rate. Batteries rest at 12.5 to 12.7.
Good Systems will charge between 13.3 to 14.7. The more load you have the lower the voltage will be depending on the amp rating and the technology in it.
@@russellp73 i can't install sound system it will eat evry thing😓
Have the battery and charging system checked. Maybe one of them is weak

im dealing with a similar issue. do you have an update on this?

03 and 04 are 03 and 04 only.
You can install a 220 amp out of a 2011, just need the plug and to switch the 2 outer wires in the plug. 03+ are all pcm controlled.
