change your battery cables and check all wires on the alternator for loose connections, expecially the grounds.

How long did the 2nd alt. last before it died? The voltage regulator is, I believe, attached to the alternator. Have u had the voltage regulator checked?

You must have blown a master fuse or fusible link.

Refer to the maintenance manual.

this happens sometimes during a jump start or a direct short in the elect system.

2004 ford freestar 4.2l Not charging, new alternator tested and working new battery.


Hotrod, Recheck,clean and tighten all connections. If you say you had new alternator tested and is working OK, the new battery must be defective. With the van running, use a DVO meter and check the battery, if it shows above 14 volts then the alternator is OK, a good battery should show 12.4, that leaves either a faulty battery not holding a charge or you have a parasitic draw(something draining battery). Which would have to be diagnosed by a good Tech.
Check the attached links,instruction and guides, Good luck

Battery keeps dying, no headlights


Check to make sure the power lead from the alternator to the battery has a good connection. Sometimes the connectors get corroded, or the wire separates inside the insulation. You can check the wire for continuity with an Ohm meter...make sure to disconnect the wire at both ends when you use the Ohm meter.
Make sure the battery has a good clean ground. Make sure the alternator is grounded to the engine and the engine ground strap is intact and has clean grounds on both the engine and frame. Test the alternator with the engine running using a voltmeter across the battery. You should read 13.5 to 14.7 volts. If the alternator is not charging the battery will go dead under normal operation. If you don't get the correct charging voltage either your connections are bad or the alternator is bad.

My '91 ford festiva will start and run when jumped but will die when the lights or radio is used replaced the altnator already and batteriy is good idk whats wrong can anyone help


You or someone will have to figure out why your new alternator is doing absolutely nothing. Not only is it not putting out enough power to run all the car's electrical systems, it is also not charging the battery, so you could start it next time off the battery and not have to get it jumped. With it not working, the car has to use battery power to run everything, and when you use lights, or radio, or any accessory, the battery runs down even quicker.
One reason alternators don't work is loose or poor connections between the battery and alternator. You could remove your battery cables (check them, if they look old or worn badly, replace) from the battery (negative first) and clean the cable ends and the battery posts till the metal is shiny clean. Do the same for the negative cable to frame ground point. Then check the big cable end on the starter, make sure it is tight. Put the cables back on-positive first, negative last, then move to the alternator and check the connections there for a clean tight connection. A couple of other ground points you could check is the engine to frame ground-somewhere on the engine is a ground strap bolted to engine metal and the other end will ground on the car frame or on the firewall in back of engine. If this ground is lost, strange electrical problems may result. One more ground: often the engine and computer wiring harness will have a ground wire coming out of the harness-a short wire-and may be grounded around the top of engine-many cars do have this visible ground, so check for it and check if a good ground.
If you do all this, and still no help, cheeck all your fuses in the under hood fuse block-sometimes there is an alternator fuse there, a big maxi-fuse. Check if good, check all fuses. If no help, you likely need a mechanic or shop to figure it out. Good luck. Hope you find it.

My 04 Ford Focus the battery light keeps coming on & going off, have fitted a new alternator belt but it didn't solve the problem. The battery connections are good. Also the rev counter, speedo & mileage clock keep going haywire when the battery light is on. Do you think it is the alternator? Or is it some other common problem?

How to install 03 ford focus alternator?


Removing the Alternator
Disconnect battery ground cable
Remove the ground wire (black) from the alternator
Disconnect the positive wire (red wire held on by a retaining nut) from the back of the alternator
Now disconnect the wire harness from the alternator
Remove the drive belt
NOTE: Some models use a belt tensioner that applies tension to the drive belt.
The best tool to use for this job is the serpentine belt too.
If you can borrow one from a neighbour you can get one at PartSource. (Part# 648451)
On other models you will have to loosen the adjusting bolt on the alternator bracket.
If you're not sure about how to remove the drive belt, visit your local PartSource for free print outs of vehicle specific instructions.
Take off the mounting bolts from the alternator bracket
Now remove the alternator from the engine compartment There. You've removed the alternator. How easy was that?
Installing Your New Alternator
Put the alternator in the engine compartment
Install the mounting bolts that connect the alternator to the alternator bracket
Connect the alternator wiring harness
Now connect the positive wire to the alternator
NOTE: Your new alternator should come with a retaining nut.
Remember to remove the nut before you install the positive wire.
If it doesn't keep the old nut.
Connect the ground wire to the alternator
Now install the drive belt
This is a great time to replace your old worn out belt. When inspecting your old belt look for signs of cracking, oil soaked, hard glazed, splitting or fraying.
All these signs mean it's time you replaced your drive belt.
If your vehicle no longer has the belt routing diagram under the hood, visit your local PartSource for a free print out of the belt routing diagram.
Reconnect the ground battery cable .

turn your vehicle on, disconnect the battery, both terminals(while truck is still on) if it dies on you, then either the alternator is bad or wiring is wrong. if it stays on, then you may have a bad battery or voltage regulator. Check the voltage on the battery before you turn it on(should be from 11.5v-12v), when you turn it on if the alternator if working properly you should have around 13v-14v.

Battery is dying with in 5 min. sitting or running? what could cause this. starter was changed out and is new same for battery. after market stereo was installed and was stolen from dash.?


if it dies while it's still running it probably needs a new alternator. you might also remove the radio fuse to see if maby the thief grounded something out.
