    If you have access to a multi meter check voltage at the battery and the alternator B terminal they should be the same round 14 volts.

Car will not start. Dash lights come up when key is turned, but are dim. When turning the key, there is no sound or click. Battery was tested at and confirmed to be fully charged. What is wrong?


Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection.
Problem is most likely the Solenoid or starting relay, whichever the car uses.
Hope this helps.

Flickering/Dimming Lights


you forgot, does it do that running engine or not.?
ok the main battery is car is doing that.
use a voltmeter, at the battery or even at the CIG lighter port.
12.6v DC, not running. rested. running voltage is 13.3v to 15vdc,

start engine, is rpm above 800 RPM at all times, or more?
if not, the alternator will be too slow, and drop out and when that happens , the lamps will dim. (a 3 volt drop does that)
1: all fuses good
2: battery term lugs clean, not green
3: fan belt to alternator not loose. slipping.
4: charge lamp on dash not ON, running.
5: check engine lamp not on, running (if yes,scan it now)
6: test the battery , batteries are LOW life objects, (die-easy-not-hard)
test the battery , using a load tester or take it in for testing, it's free.
or try a spare battery from another car. do not reverse POLARITY.
this gets the lions share.

My 1994 honda passport will not stay charged new altnator and new battery


is the engine running at 800 rpm or more.
if engine RPM is way low the Alternator will die out.
trans light , where is that? name it. exactly
lets focus first on the engine, and RPM
does the dash have a tachmeter, ? yes, then use that.
we keep a hand tachometer (optical , ready for no tach cars)
RPM is everything.... maxwells laws. and such.
1: rpm 800 or more all the time. rule 1, do not skip this.
2: belt to ALT not slipping'
3: battery good. terminals on battery cables tight both ends and
NOT PACKED in green corrosion, .
4: alternator case is grounded good.
5: The connection and ALT, all good.
6: you key on, and the dash charge light must turn on,
if not fix that now, on old cars, the dash light , causes the ALT to self excite, if the lamp burns out the alternator boots up DEAD.
or fails every other car starts. (does)
7: new alt is the wrong alt. zillion wrong ones, only 1 works.

1997 bmw 328i dash lights all lit up at once and after several minutes they faded, and eventually the headlights and dashboard lights dimmed.


Alternator. Have it tested with a voltmeter while on the car and running. Or take it off and have it tested. The current to run the car and the accessories is from the alternator when the engine is running. The battery light coming on alerts you that the alternator is not doing its job.

Car will not crank and the timing chain is fine


Well, that's good, but even if the chain was broke, the starter would still be tryiing to start the car. Since your starter wont crank the engine over, your start circuit has a malfunction. Possibly the starter went out, so you need to have that tested for a malfunction. A simple test of part of the circuit is to turn the key to on.. Now your dash warnimg lights (oil, alternator, and check engine light) should be on. Are they on, and your gauges working? If not you have lost power to the ignition switch, so check your battery connections. If the key switch turns the dash on, then turn key to start. Do you hear a click from the engine area? If not, have the starter checked. If you do hear a click, or several clicks, then power from the switch is causing that click, probably at the starter. Turn the headlights on and observe them. Are they bright? If not, charge the battery up. If they are bright, watch them while a helper turns the key to start. If the lights go dim in start, probably a bad starter. If the lights don't dim, it could be a bad connection somewhere, like the battery or starter. Good luck

1995 mercury villager will not start i turn the key and all the lights come on but no click no nothing.... my husband could get it to start by jumping the starter so he replaced the starter nothing he then...


mcdevito75 her, My immediate thought is a dead or weak battery, but it could be a bad starter also, here"s what to do, inside the car turn the key 1 notch to the on position, note the dash lights, now turn the key to start and note the dash lights again, do they go dim?? if they do you most likely have a weak battery, if the dash lights do not dim, open the door so the interior light comes on, any interior light, try to start the car, if the interoir light dims, you have a weak battery, if it does not dim with the key all the way to start, check and clean the battery connections, and suspect a bad starter. Any electrical appliance can go bad very quickly. Also if the battery is2 years old, replace it.

1990 buick no start turn key dash lights go out and all is dead


When you say "turn key dash lights go out and all is dead", do the lights come back on when you turn the key back to "off"?
With key off, try turning on your headlights- are they bright?
Flip to high beams-do they get brighter?
**If lights get dim while trying this, it's the battery-(dead/needs charged or replaced-which may have been caused by a bad alternator).
Leave lights on, now turn your ignition switch to "on"-do the lights get dim or go out?
Try and start the car-anything change?
If the lights were fine until you tried to start the car, more than likely your battery terminals need cleaning/tightening.
The lights should at least get dim when you try and start the car but only while the starter turns over: when the engine is running your lights (as well as all your other electrics) are powered by the alternator.
If you do all this and lights are okay all through this procedure, your problem is probably in your starter circuit. (Starter relay, ignition/key switch)

Hope this helps.

Issue with dash lights dimming while driving,


If the battery and alternator tested fine. I would have the charging system rechecked when engine is hot and at high rpm's. This way the checks are being done as if you were driving and driving for a long time. Alternators can work fine when cold but weaken when hot or stop working. This problem is not rare but only is seen occassionly. Unless it was checked at an electrical shop the average shop doesn't run these tests for they don't see the problem often enough to automaticly run them at all times. Good luck and let me know how you make out.

Won't start lights dim and then brighten


Did you try to boost battery? Sounds like low charge. Check battery terminals for tight and clean as well as groung connection at body and power connection at starter for clean. If battery OK test for power on starter wires. Large wire will have contant battery power small wire will have battery power when key is in crank position. If power ok on both it will probably need a starter. Hope this helps...Good Luck.
