Alternator is good battery is new but no power after siiting an hour

have battery and alternator tested most auto stores offer this service for free

Could be either, or could even be a failed starter or other issue!
No magic bullet fix here or "fix" button... you'll need to test the battery first, and once you have it fully charged it should start the car. If it does not, next suspect the starter. Once you have gotten the vehicle started and have driven it for awhile, turn it back off and let it sit for two hours. After two hours, feel the BACK of the ALTERNATOR. If the back of the alternator is hot after two hours, replace the alternator.

Does the engine crank, but not start or will it not crank?

If not cranking, test battery, clean post and check wires for corrosion and good contact. Also check the ground wire between the engine block and the car body for good contact. If all good there, may be a problem in the ignition switch.

If the engine cranks but will not start, check the pressure on the fuel rail. If good pressure, check the ignition module.

This car MIGHT still be under warranty? Have you noticed if the brake lights are stuck on all the time? This sometimes happens when the switch on the pedal sticks or pops out of place.
Something might be draining the battery. A power seat switch can do it.
I'd take it to Ford and ask them if it's under warranty or service bulletin.They might fix it for free and at least they can tell you what's wrong. don-ohio (:^)

That could be anything from a bad ignition switch to a faulty neutral safety switch or a starter motor going bad. You need to test for battery voltage at the starter "S: terminal to see if you are getting the proper voltage to the starter solenoid.

it could be your bat but if its completely dead then your alternator is going bad or your charging mecahnism. autozone will check that stuff free

It could be the alternator but is most likely the low battery. Best to start with the simple things. to check if its the battery disconnect the low battery when you stop. Check the low battery then after 12 hr's check it again if it has lost power then that's the problem. If this does'nt sort it repeat the process with the main battery as although its good when you have checked it I can still loose power when sitting. If it is not a battery problem check the under bonnet light, boot light and glove compartment light dont stay on when closed.

What engine? 5.7? If yes, replace the distributor cap.

See your other post. Good Luck, RAC

Interesting problem. There are a number of things that can contribute to these symptoms: Battery not holding charge, charging system not working, bad/corroded battery and/or starter cable connections, and of course something draining the battery when the ignition is off.

Before doing these tests, make sure the battery is fully charged by disconnecting it from the car and charging it 24 hours with an external battery charger.

Is the charging system (alternator) working? Accords have an idiot light, not an ammeter/voltmeter, so it could be your car isn’t charging and the indicator light is burned out. Connect a voltmeter to a fully charged battery and observe the voltage (should be about 13.8 volts). Now start the car and observe the voltage again, should be higher than before (around 15 volts). If the voltage doesn’t increase at least slightly either the alternator belt is loose and slipping or the alternator is bad.

Are the battery terminals tight/clean? Any corrosion on the terminals or wires? How about the end that connects to the starter? How about the ground wire to chassis? Any corrosion could produce an intermittent connection problem that acts like a dead battery.

The battery may be new…but is it good? Charge it, connect it and confirm the car starts. Then DISCONNECT the battery, let sit 24 hours, re-connect and try to start. If the battery now acts dead maybe it is bad. Exchange under warranty.

And last, something is discharging the battery. First question, do you have any non-Honda add-ons like an aftermarket audio system with a power amp? Audio power amps have a direct wire to the battery for greater power, if the amp isn’t turning off then you’ll have a drain. Try disconnecting such equipment and see if your problem goes away. If that’s not it connect an ammeter in series with the battery with the ignition OFF and start pulling fuses one by one until you find what’s causing the drain.

Hope this helps!
