Voltage isn't the problem here. You are correct in using the 12volt battery. However, what you need is more power and power comes from the amperage. Make sure the battery you have, has sufficient CCA (cold cranking amps) for your new starter. Try removing the battery cables and jumping from your car. Make sure you ground the black lead on your car (not hooking the black cable up to the battery directly) if that doesn't start your mower, you have a different problem all together possible being the new stater and hopefully not compression problems steming from the intake and exhaust valves. There are typically saftey switches to shut down or prevent the motor from running. Easy trouble shoot, if the starter kicks over, it's not a saftey switch.

My 2004 Ford explorer sport Trac won't start up after short drive

O.K. Bernie you say it cranks & tries to run //// you have plenty of power in the battery not a cable issue but what I needed to know is does it happen then start again and then you drive a little bit and it happens again then you wait 20 minutes and it starts again or are you stuck with a lot of cranking power from the battery but no start and then later it will start again /////// there are a lot of things that could be happening so you must bare with me here I'm not at the vehicle first what is the condition of the ignition wires(do you have regular spark plug wires or a 4.0/4.6 with coil on plug boots)if it's regular wires they may be old and leaking voltage and will cause the no start especially if it has rained or is raining at the time because the +voltage leak is able to jump/arc to the engine - ground instead of firing the plugs ==no start next are the spark plugs new/old in gap if they are (a) out of gap to much air space for the + voltage to make contact with the bottom electrode so when the truck starts and runs it's barely making it but as the engine gets hotter fuel is vaporizing fast and the spark plug is not producing the voltage to cause the fuel combustion explosion that happens in the cylinder for each plug because they are out of gap they'll fire up a cold motor but not a hot one /////stay with me Bernie there's a lot to explain here next/// do you have coil on plug with spark plug boots yes/no //if yes you must take each one out & inspect them for (a) very soft (b) cracks in the boot ////check by flexing the boot back N forth to see the strength of the boot should be stiff if they are very soft there's probably a leak in it even a pin hole will cause problems with leaking voltage also squeeze the ends of the boots multiple times to see if there are cracks in the part where the spark plug fits into it below you will see the wires & boot with the contact for the coil the spring you see if this is your system of coil on plug you must after taking the boots off pull out the spring and look into each coils hole at the contact it will look like a blade that the spring fits over if it is green or has a powdery coating clean it using brake parts cleaner or alcohol & emery boards that the ladies use for there nails trim it down and get that blade contact shiny also check the base of the coil on both sides === plug side from electrical system coil connector/spark plug side for cracks marked below with ^^^/>>/<</// if this kind below check the coil towers>>>>>> for cracks on the coil and the actual wire you plug in

Trouble starting had startor motor replaced smething is draining battery 12 v cranking voltage 6 volts

something electrical may be remaining on like a light somewhere that you dont normally see like a trunk light that should be off, also could be something with a blown fuse with power still going to the relay area (but it wouldnt affect anything because of the blown fuse)

It is almost definitely a bad alternator, but could also be a limited number of other things. A bad battery terminal could cause this problem as well or other loose or corroded connections. As for your 12 volt reading on the alternator, I should explain a little about electricity. If electricity travelled down a highway, the number of lanes would be the voltage and the speed limit would be the amperage and the wattage would be lanes multiplied by the speed limit. 12 lanes travelling at 2 miles per hour aren't getting anywhere fast. Also, a car battery's charge voltage slightly above its' output voltage, so it should be roughly 13.4 volts up to about 15 volts.

If your battery is years below you need to change it to new one if this happen the voltage become low mean your the battery plate is getting week, or the water becoming low, battery wont last for 3 years you are lucky if you reach that time. For better performance battery life is only 1 and 1/2 years and be ready to ready replace it soon

My 06 Coblat LT wont start unless I jump it almost every time. Is this the alternator?

If it starts and stays running it's most likely the battery. However,With a voltmeter while the car is running measure the voltage at the battery terminals. If the voltage is about 13.5 volts to 14.5 and there is no battery light indicator on in your instrument panel, your alternator is most likely good and trying to charge the battery, If the battery light is on and you have lower than 13.0 volts at the battery most likely the alternator needs to be replaced. Turn the ignition off and measure the voltage again if it's 12 volts or less try charging the battery with a trickle charger (2 amps setting) for about 12 hours.if the problem persists replace the battery.

Hello, Leoch 12V battery, DJW12-12Ah, is no longer charging. We bought a John Deere riding toy at a local Toys R Us in Michigan three years ago. My children have only used it for two summers and is...

Sounds like a battery problem.
Lead acid batteries should to be charged every 3 or 4 months even if they are not being used, or they can slowly self-discharge and will start to deteriorate if the voltage drops below about 12.2v (for a 12v batt.)
They can then be difficult or impossible to charge. The charger can see this as fully charged and show green.
You can test for this if you have a voltmeter. You should be able to work out if it's the battery or a connection (or the charger).
Measure the battery voltage (use a DC voltage range greater than 12V). The normal voltages you should see:
A) Key off, no charger: >12v, <14
B) Key off, charger connected: >12, <14.2, but higher than A)
C) Key on, no charger: >12, <14, but lower than A)

If voltage A) is low and immediately goes high when the charger is connected then the battery needs replacing.
If A) and B) are exactly the same then it could be the charger is not connecting or is faulty. Measure the charger output, should be >13.8v (unless it's an "intelligent" charger in which case it might need some voltage applied to its output before it starts charging).

Note: If A) and B) are low, say <8v it's possible that an "intelligent" charger will refuse to start charging. In this case it's probably worth jumping the battery to a good 12v battery (e.g. car). Be very careful to connect the batteries (+) to (+) and (-) to (-). Leave connected for 10 - 20min or even overnight and then disconnect jumper leads and check A) and B) again. Sometimes a battery can be recovered by this method (it's unlikely to regain full capacity though).

1997 pontiac sunfire will not start...not battery, lights still come on, sparking from battery when tested, gas tank full...electrical problem? How would I know if starter motor gone??

well make sure the battery connections are clean. Just because the lights come on means nothing. If you can go to the starter there will be a larger wire about the size of you're pinky and a small wire if you have a volt meeter check the voltage at the larger one with the key on it should be about 12.6 volts if not its not going to start now hook the meeter up to the small wire and have some one try and start the car if you have 12 volts the and it wont start tap the starter with a hammer if it starts the starter is going out if it dont start the starter is junk also good luck.

My 2002 suburban will not start

First thing I would try is checking the actual battery voltage. Most batteries should be roughly 12.5 if new when sitting at idle. If the lights dim and relays click this is normally a sign of a weak/bad battery connection or possibly a discharged battery. If the battery has good voltage, and the lights continue to dim I would suspect checking the primary wire going to the starter with a 12 volt test light. You will want to check the smaller wire going to the starter and have someone turn the ignition to start. You should have 12 volts there. If you have 12 volts and the starter does nothing I would suspect a faulty starter at this point.

you have a short in your electrical system,

try removing the positive all the wires attached to your positive pole of the battery, then slowly attached them one by one and observe which one would indicate a big spark. if you would pin point which one then you can start from there.

if there is no big spark, then you can bring back the new battery from where you bought it and have a thorough check applied to it. who knows, you could have a factory defect in the battery.

you can also test your new alternator by using a volt meter.

first, check the voltage of the battery, it should be at least 12 v dc or more.

then start the engine, it should read at least 13 volts or more..up to 13.8 volts, then rev the engine and still it should only read up to 14 volts.

then turn on the head lights, ac( if you have ) and check the voltage again. at idling speed, you may experience at least 12 v only on the battery because of the load you are applying.

then rev the engine a little bit, you should have at least 12.8 volts to 13.5 volts.

if every test the voltage are ok, then you have a good alternator.

i hope i was able to fix ur problem,

tnx 4 using fixya,
