2007 rav 4.Battery light came on, drove 20 miles on hwy. stopped, shut car off.started car with a very slow crank. Power steering was gone, all warning lights came on barely made it home. now dead.


Used your battery up just getting home. Now recharge the battery, and test the charging system- could be a bad alternator not charging the battery.

Normally, the alternator powers all the car's electrical needs when the engine is running. If the alternator fails, the battery will then be used to run the electrical needs until the battery is depleted, then the car will shut down. Dead, just like yours. No big deal, just find out why the charging system stopped.

My 2003 nisan bluebird had a faulty selenoid switch which was replaced . The engine cranked and run for a while.Now the engine refuses to crank and would sometimes crank and run only after some heavy


no crank
did you first try a live hot jumper cable crank? off a live donor car.
AAA Tow style.?
USING REAL JUMPER CABLES, not china tin foil?l
that be first. ok it always cranks , that means the battery is dead, not charged,or the alternator is shut down or you have phantom drains.

if the battery known good, and charged
we can hotwire the starter, if that works the starter is good.
if not bad.
if it hot wires ok that means the key line is dead.

this is how this is done,
if key line dead, wiggle that silly slushpump shifter lever or try cranking in neuTRAL.
OR HIT STARTER CASING WITH HAMMER 3 TIMES(3 FOR LUCK) CRANK NOW.?

THIS WORKS ON ALL AT CARS.

MY CAR: (X3)
m/t CAN PUSH START, IT , AND GRAVITY START IT.
AND SHORT THE CLUTCH SWITCH TO FIX BAD KEY LINE;.

If all this ok the ignition switch can be bad, or bad power distribution can not teach in 1min.

99 suzuki vitara v6 turns on all power but wont


the starter uses 10x more elect. power than the head lamps
or 100x more than dash lamps. it means little.
what matters most is jumper cable starts.
does it crank with jumper cables to a running, donor car,(aaa jump)
no bad starter
no, bad starter key line( immobliizer or such) ask how to test.
yes, cranks great, now.
that means the battery was dead,
i charge the battery and it now cranks, due to lights left on or
charge system failure, if battery goes to 13.3 to 15v running good
if on the charge system failed. (causing battery discharge)
if after charging a battery it will not crank car, its a bad battery (jumps ok)

Car was cranking fine then I shut it off went in a store and came out and it wouldn't turnover, so I thought the battery was dead so I got someone to jump me off. But when we put the cables on and waited a...


Hold on!!! 3 elements, power/spark/fire, fuel, air. If the car cranks, there is power, if it wont ignite it's usually the fuel system, did you check your fuel level? If you smell gas and its cranking then theres an air problem but thats rare. And people, if you have a car sit for a month or so, yes you may end up with a drained battery as some cars have alarm systems built in. or like my 79 vette a phantom power leach. And please jump your vehicles properly, first leave jumping car running, connect red/+ to good battery then Red+ to bad car then neg black- to bad car battery terminal then black to frame of good car. never hook up cars while jumper car is not running as the drain is immediate and you may end up with 2 dead batteries. and just because you start dead car doesnt mean the battery is charged for the next start up, you have to charge it with alternator by driving at least a good hour. if your battery is good then go to fuel system...start with the tank hole...is there gas, next is pump, then filter then carb or injection but fuel regulators and hoses are there too. good luck

Short answer, your batter is bad. or is disCHARGED:
Long.:

wont crank?
no engine, cranks ,unless the starting system works.
unless pushed fast, like my car or i park on a hill and coast jump my car.(M/T tranny rule)

NO crank, is the true failure here:
slow Cranks are , bad battery , or a discharged battery , due to bad charging system or parked for 3 months or longer.

so ill assume its NO CRANK.
I turn the key TO START and the starter fails to CRANK.
the starter motor is dead. (key clue 1)
so i attach a set of jumper cables to my Caddy, running and this car
now cranks and RUNS (you left that out. above, huh? runs)

turnsover means nothing, because the engine starter turns over
and the engine can turn over and the engine can run,
once running the EFI system SUSTAINS runninng.
so there are 4 states there. (4 phases )

No cranks #1 reason to be slow , are a bad battery
so I charge that battery, and see how if it cranks , now?
it dont crank means a bad battery
it does work( crank) see how long it works.../?
if it dies again, or better, check the cars Alternator for by measuring
accross the battery terminals running , with any volt meter.
13.3 to 15vdc is a good alternator running the engine.
if NOT, the charge system is bad. (system)

On some cars the IMMO can block Cranking or for sure blocks
fueling after 2 seconds. So. watch the IMMO light on the dash.
Immo is the Immoblizer. option.

Yes, a car will keep running with the battery disconnected, although that is not a good idea with all the sensitive electronic circuits on cars today. You can fry something expensive quickly. It will keep running because all power to run everything is supplied by the alternator, not the battery.
Have the battery charged up again, and see what happens. I don't know why it went dead, unless you have a charging problem. Does the battery/alternator light go off after the car is started?

91 Cadillac Deville battery keeps losing its charge. I charge it up and it runs , and then I dont use it for a few days and it is dead when I go back. I had alternator checked and they said it was fine,...


you need to do a load test on the battery first to verify its good,charge battery fully,turn headlights on high beam,wait for five min and crank engine with lights on,see if you still have a good cranking time,if you don't replace battery,if you do charge battery up to full again,check voltage at battery post with a multi meter,
should be 13 volts at minimal,now turn headlights on ,heater on,and flasher on and pull in gear,have a friend check voltage at battery to see if it is staying above 12.50 volts,if it is below 12.50 the alternator is not putting out on a load,replace it.if these check out good,check for dome or hood or trunk light not shutting off ,or something else draining battery.

Draining juice out of battery like a open relay or something...


Try going to Autozone or local auto parts store they will check your charging system for free a good battery should not go dead just sitting there ,must be something draining it a light in the trunk or glove box or a radio that doesn't go off or a dome lamp
