Put new alternator on 2004 trailblazer now check engine light is on and automatic running likes won't work


Was not like that before you had the alternator installed so I would have who ever installed the alternator go over everything they did because something is messed up with the wiring. Could be nada more than some disconnected wires.

Okay, so I bought a 2001 Ford Focus zx3 5 speed, and when I went to go test drive it, the alternator went (so I thought). anyway, he lowered the price, and I still got it and replaced the alternator. about...


your alternator is still under warranty get a new one, based on your info thats the problem, just make sure when installing the new one the battery polarity is correct because that is one cause of damaging the alternator, reversed polarity will burn regulator ic, once you have installed the new alternator run the engine on idle remove one of the battery connector if the engine still run it means the alternator is charging, if engine stops check wiring connection

Changed alternator now engine won't stop reving


I'd first check all the vacuum lines that you may have removed to install the new alternator. Make sure you didn't forget to put one back or accidentally knock one loose. Does it do it while driving too? Check engine light? Codes?

2005 lincon aviator charing system 12.2 volts after alternator install


check the black/orange wire at the alternator for battery voltage if no power check the fuesable link ( A )

check the orange/light blue wire at the alternator for battery voltage if no power check the fuesable links ( B & C )

check the light green/red wire for 12 volt with the engine running if no power replace the PCM.

if all wires have the proper voltage then replace the alternator

GOOD LUCK

Why does my battery light stay on after i installed an alternator and new battery


Hi,

The Battery indicator light usually means the alternator is not charging the battery. Most common solutions would be a bad alternator, bad connection, or loose alternator belt.Since the battery and alternator test ok then check the connections to the alternator and battery.
The alternator should have 2 connections.

Good luck...

2 Dashboard lights have come on 1 check engine


well if the battery light came on that means your alternator is not charging the battery,,you need a new alternator,,,and maybe a new battery if it killed it,,,,that set the check engine light on,,,,,for it not charging,,,,,do not buy a aftermarket alt,,,,only saturn/gm,,as they do not meet gm/saturn specs and you will install it and still have a battery light on,,,,,,you need a factory alternator,,,yes it costs more,but unless you feel like putting a few in and out to find this out,,,,,

Battery light is on


this light points to the alternator not providing enough voltage to keep the battery charged. most alternators should have 13.5 to 14.5 volts output. continuing to drive the vehicle like this will cause the battery to go dead. have your alternator tested on the caravan by your local dealer,repair shop or some auto parts stores can do it. a remanufactured alternator will cost around $100 to $200 plus diagnosis and installation.

Just installed a new alternater and the battery gadge is reding discharge I had the battery checked and its good. Can you help


Check the 'Bat' / 'Charge'/ 'Alt' indicator on the dash panel lights when the vehicle ignition is switched on prior to starting the engine.
This indicator should extinguish within approx 1 second of starting engine.

If the indicator is not operating the alternator cannot provide charge current - check:-
1) the wiring connections to the new alternator,
2) the indicator lamp is not blown,
3) the alternator is properly grounded.

If the indicator light works normally, check the output voltage of the alternator is approx 14.5v when the motor is running.
If its about 14.5v, the battery should be charging.
