Hi Kurt, I'm glad to help!
Kurt, we need to first check the "FUSABLE LINK" that powers the Alternator. The link is usually a larger GREEN WIRE and either attaches to the battery cable OR attached to the Alternator. It is in different places depending on manufacture. When you find it you need to free it up so you can grab it and pull real hard. NOTE: If it get longer then its bad and needs to be replaced. If it doesn't get longer then check all related fuses and relays if applicable. Hope this helps and have an awesome day Kurt.

Stecorbett:

May I suggest that you drive your car to one of the major auto stores and they can and will check your alternator for you to make sure it is good/bad.These places like AutoZone do this all the time. They do not charge for the check out. (Of course they are hoping that if you need a part you will buy it from them.

One other suggestion. If you do need a new alternator, get a rebuilt one. It is cheaper and most always comes with a warranty.

Hope this helps Good luck Loringh PS please take a moment to give me a rating

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.

I don't think it's a battery. The ticking noise along with the dead battery leads me to believe you might have a belt/pulley issue. The serpentine/accessory belt and pulleys are all part of your charging system. It's how your alternator charges your battery. If there's something up with one of the pulleys or the belt (slipping?) in that system then your battery isn't going to charge properly. I have 6 yrs and 225,000m on my original battery in my Jetta - although I have a new alternator because the pulley fell off of mine...

SOURCE: 2003 Pontiac Vibe with 110,000 miles. Over a three

When you say the battery has a full charge, what voltage are you reading? 13.2 volts for a 12 volt battery (2.2v per cell x 6 cells). The solenoid is the usual suspect. My dad had a truck that occasionally wouldn't start and he wacked the starter solenoid with a crescent wrench and then the engine would turn over fine. The facts are that the solenoid is nothing more than a moving contact big enough to carry all the juice the battery can dish out. Over time the contacting surfaces wear away. The worn away contact material doesn't escape the housing, so the solenoid housing fills with dust. Dust impedes the movement of the contact. Wack the solenoid with something like a hammer or wrench like my dad did. One thing though - be careful not to short out anything or hit hard enough to dent the housing. If the wack does the trick, then thank my dad...

Put in new altinator onlly reaing 10 volts


With the motor running, the voltage reading at the battery should read between 13.90 & 14.80.
Get a good fuse tester, test each fuse with the ignition switch in the " on " position. most fuses can & should be tested while still in the fusebox. There are fusible links in the fuse/relay box under the hood that are the main source for the alternator to charge the battery. the fuse tester may not work with these. they will need to be visually inspected with a flashlight & or glasses. They may have a see-through top to see if they are blown or not. Use the tester for the normal fuses. There is a fusebox on the left side of the dash that needs to be checked also.

1989 subaru gl 2wd auto trans Intermittantly won't start, just clicks, upon jump start car will started ok for a few days then same thing again, battery ok, new starter assembly installed 6 weeks ago,...


if battery is ok and new starter installed then the problem would be your spark plugs or your fuel pump...If It's not getting fuel to the carb make sure there is pressure in the needle valve on the fuel regulator.

Killed then we jumped started it it went about 2 miles and killed again. we jump started it again,got it running as soon as we took the jumper cables off the running car it killed


if you have a bad altinator it will drain your battery causing the enguine to stop running. and if you killed the car that was jumping it then i def would get the altinator tested on both cars as jumping a car with a bad altinator can cause charging issues on the car doing the jumping.

My 99 Jag xj8 turns over slow with a battery thats ok. like it is dragging, the car has been in the garage for months now. only has 58000 miles on it.


ok, just because the battery is cranking over, does not mean that the cell inside the battery are not weak. they will always take a charge. but as to how long they will keep that charge is the problem. all 12v systems are as follows so check yours.

all should have no more than 14.5v during a charge(engine running) anymore it will fry not only the battery, but other componets as well.

all should have no less than 12v with the engine off, and a load test of no more than 15sec, and a drop of 10v or higher should be present.


with a good battery and alt, there should be a drop in voltage no less than 8v during a start crank, and after it starts it should rapidly return to a 12.5v to 14.5v charge. I suggest to have the battery and altinator tested for a load, and cell state.

Turn ignition key and just get click from soliniod under front hood one white wire and one black wire and dash lights go out,new batt and starter fitted


here are a couple of quick easy thing to do to isolate what the problem is. if your battery is new and fully charged. then take a set of jumper cables and put one clamp on the negitive post of the battery and its corresponding clamp on the alternator bracket on the motor this will insure that you have a complete ground which you need to ingauge the starter. in dc current the amperage is constant and the voltage is variable. a good ground is needed.
if the charge in your battery is depleted jump the car to get it started. then remove the positive cable from the batteries possitive post if the car stays running then the altinator is charging this illiminates the alternator from being the problem. if the car stays running its good if the car dies then the altinator is bad and needs replaced.
check the wires hooked to the starter to make sure that they are not gounding out on the block or the exaust.

Only when i come to a complete stop, while in drive, the battery and emergency break ligt come on...


Idle is to low,or the alternator is not charging enough.It needs to be 13.65 volts,to 14.25 volts at the battery with the lights on,and high blower on.If it is lower than this,replace the alternator.

Car won't start


buy a cheap volt meter check voltage on both sides of the starter seleniod on the fenderwell if you have 12 volts on both sides while cranking test voltage at starter if you have 12 volts at starter with fully charged battery and it doesnt start you will need a starter it also sounds like you might need an alternator once you can get it started

if the charging circuit is low, then it appears that your alternator is going bad....

Battery terminals, when car is off, should read 12V+-.2V. When the car is running, terminals should read 13V-14V=-.2V
