SOURCE: 1994 Jaguar xj6 battery loses all power after

you have a battery power drain.  Remove one fuse at a time until you find which circuit it's in.  This will take a while but it will find the problem and it's free.

98 chevy malibu my alt isnt charging new alt batt test good cut out the fuselink on starter the alt wire runs thru firewall If i run a wire straight to the batt it is putting out 19v any suggestions


Did you check the fuse in the under hood fuse box ? GEN / BATT fuse 10amp . Is your check engine light on ? This is a computer controlled charging system , it should have four wires connected to the alternator . 1 - the heavier wire on the back ,this comes fro the starter - the one with fusible link , you could have checked for battery voltage with voltmeter ! The three other wires in the connector are the orange one ,this comes from the GEN / BATT fuse an should have battery voltage ! The last two come from the PCM - engine computer . The gray wire is the turn on signal from the PCM an the Red wire is the control from PCM ! Charging System Wiring Diagram MOTOR Magazine Article MOTOR Information Systems

1994 E150 van ford no alt power have changed the alt. charged the batt


There is a fuse or fuseable link between the alt and battery, and the alt gets a signal from the key to activate the voltage regulator.
I would check for batt voltage at the alternator and you may need a wiring diagram to check for key voltage.

The car died lights went dim then engine cut out with the key on there is no batt light on the dash. I unpluged the 2 wire conector at the alt and started the car after I charged the batt. still no batt...


sounds like you either have a loose wire that is preventing the alternator from charging the battery and keeping you going or the alternator has a bad diode. Take it to an auto parts store and have them test both battery and alt while the car is running.

I got 04 ford focus good battery alternator but no charge also i check fuse box next t the battery and the other inside the car everything is good but my alternator still dont charge


1) check 10A fuse in the batt. juction box (eng. comp.) hot at all times.
2) check the large red battery wire to the alt. for good conn.
3) make sure the alt. is grounded properly
4) gray wire sent from the alt. to the PCM
5) blue wire sent from the PCM to the regulator (alt.)
6) small red wire power frorm the 10A fuse
if all checks out and still not charge replace the alt.

Replaced starter, solenoid and battery on my 88 tempo. Started fine that day next day dead battery any suggestions?


Check voltage regulator. Also try to see if anything is possibly draining the batt while not running. Is the alternator charging at the right voltage? Do not remove terminal from batt to check alt. this can burn out a diode in the alt.

My alternator went out, or so I thought. I replaced it and the system still won't charge. I just replaced the battery and I know it is good. What could the problem be?


battery cables corrosion or lose. Also could be lose nut on alternator where large wire is. Clean and tighten all wire ends + - and alt. that don't work get an dc multi meter and check voltage on alt at nut when running should be like 13 to 14.5 volts black to batt ground and red to alt on multi meter. if it's not 13-15 your alt. is bad. Get your batt load tested free at autozone.

1989 Ford F250 pickup- amp meter reads backwards


If you had a dead short when connecting the neg. battery cable, the battery was being installed backwards or you had grounded the alternator + lead somhow.

I suspect whnen you installed the battery, you have burnt all of the diodes out in the alternator and the AMP meter is showing no charge. The AMP meter also could have taken a beating in the reversal.

Check the battery in in correctly first. If not reinstall or get the correct battery. Then check the battery voltage with the engine running. If less then 13.2. Replace the alternator again.

Good Luck

Charging problem 1991 volvo 240


14.6 means your voltage regulator or diode is suspect Despite having new alternator .Ive cross refrenced your smptoms in the haynes workshop manual and alternator is your only end answer.The haynes test is to start vehicle with multi meter connected across the battery terminals,increase the engine speed until the reading remains steady should be approximately 12 to 13v and no more than 14v.switch on as many accessories as possible(headlights heater blower radio etc)check that the alternator maintains the regulated voltage at around 13 to 14v.If the regulated voltage is not as stated then alternator is to be repaired/replaced.Good luck with it and a happy new year.

2001 F350 Charging problems


actually the only thing i can recomend is to have the alternator replace again for warranty and before starting the truck charge the batteries very well with a baterie charger make sure to charge them individually because with a low batterie the alternator has to put a lot of load and might burnt again
specially with dual batterie.
