Low voltage Won't start

Check your honda accord exhaust pipe to mak sure whether it is frozen, or the ignition system is not working well..

Hi Leigh, Have the charging rate of the alternator checked. If you have a voltage test meter, select a voltage range above 15 volts DC and measure the voltage across the positive and negative poles of the battery. It will show a low voltage before the vehicle is started. Jump start and measure the voltage again. If the voltage is about thirteen volts or more, the problem is with the battery, which you'll need to replace. If the voltage across the terminals remains at the voltage first recorded before start up, the problem is with the alternator. Regards John

Ford products are sensitive to changes in Battery voltage. The system views low Voltage as an attempted theft and makes the Alarm go off.

Remove the Battery, return it with a full charge or new Battery. Some other symptoms would be slow cranking or clicking like a dead battery. The Antitheft reduces starter Voltage to around 7 Volts making starting nearly impossible.

Please rate my info. If all else fails, the Identity in the car memory may no longer match the identity on the car keys. You would need to have a Dealer rematch the keys to the car.

The alternator may be charging at 14v but if the battery cannot hold charge, then a low voltage issue may be present. If a jumpt start worked to get the vehicle going, then I'm assuming your battery is close to dead.

Many batteries may only last around three years. Check battery voltage at rest before starting. Any voltage in the low 12v range may be a sign of a faulty battery.If low voltage present, then perform a parasitic drain test:1) Disconnect battery POSITIVE terminal and connect ammeter in series, between battery positive terminal and positive lead.
DO NOT START THE VEHICLE!!

2) With all vehicle doors closed, alarm off, lights off, radio off, and all other accessories off, wait for around 20 minutes and then read the ammeter. A healthy system should read about 0.03 amps and little more. If reading more, then the vehicle could be suffering a parasitic amp drain, and you will need to locate this issue.


3) Reconnect battery when finished.


If no major parasitic drain present, yet low battery voltage then:


4) With vehicle started, check the voltage charge from the alternator. Connect voltmeter to battery terminals and take reading. A healthy system should be charging in the range of 14volts or down to around 13.5 volts. If reading around 12 volts only, then check and replace alternator.

THAT PART ABOUT BARELY GETTING HOME BOTHERS ME LOW VOLTAGE TO COMPUTER CAN BURN IT OUT HAVE IT TESTED GOOD LUCK CHECK RED FUSES

First thing to do is to have the battery teasted..Because a battery with low voltage will cause unusual things to happen..Take it to autozone ,,and have the battery load tested and they can also make sure the alternator is charging...You may have two problems going on..If the GEM module is getting low voltage it will cause that to happen...The GEM operates your inside components ,,like the wipers,,and dome light and stuff..

Check the battery terminals for cleanlyness and tightness.
Check the voltage when stopped, it should be 12 volts.
Check the voltage with the motor running, it should be 14 volts. If not the alternator is not charging.
If the battery voltage is low then it may need replacing.

Sounds like you have a low voltage problem.Take a volt meter and battery voltage first it should be 12-12.7 volts not running and key off.Then start engine and check the voltage coming out of the alternator it should be 13-14.7 volts.If one of these are not within these specs then replace which everone that is bad.

Hi, if the car engine fails to crank, there is a fault in one of the components in the battery/ignition/starter circuit. Low battery (Check battery voltage, recharge if low, or jump start with another vehicle or battery charger). Bad starter relay/solenoid (Check for voltage at relay, if relay has voltage but there is no "click" when key is turned to start, replace relay). Bad ignition switch (Check to see if voltage reaches starter relay/solenoid when turn to start. If not, check for open P/N switch and brake or clutch pedal switch. Replace ignition switch if defective).
