Problems while charging a battery

it wont crank, no A/t car starts unless cranked first. (a key point)

fix head lights first. this is a feature in all cars.

that is SIMPLE and HOT all the time

they must work at all times and is the top way to diagnose

electric problems



you have a dead battery,.

only why remains.

i bet it cranks jumper cable started, call AAA or buy some cables.

or swap in a charged battery , or heck charge yours, buy a charger.

check fuses.

check battery lugs for green death?

check battery voltage. at 12.6vdc, if not charge the battery

if the battery continues to disgharge.

that is called phantom drains, or bad battery .

or the alternators is bad.(system)

once started the battery volts must be 13.3.to 15v, if not the charge system is bad ,(fuses, belts slipping and lots more possibles)

You may have fried the fuseable link that comes off of the positive battery terminal. Disconnect it from the post as well as the negative cable from the battery. Check the continuity along the length of the cable anywhere thrre is no continuity the link has blow, replace it or the entire cable.

P0230....Fuel Pump Primary Circuit

P0725....Engine Speed Input Circuit

Here are the codes but i have no idea what could be causing the problem ,Perhaps the dead battery has done something to the ECU ,i would check the fuel pump feed out but first i would charge the battery for at least two days on trickle charge so the engine will crank ok as if the battery is too low this could cause problems although it should start with a jump and charge itself up but if the battery is too low it will not charge as a alternator needs power to produce a charge unlike a dynamo

Sounds like a ground problem allowing a back feed issue.

Make sure your battery is grounded to the engine and frame.

try taking off the battery terminals and see if they have dirt and grime behind them thats not letting current flow clean them with wire brush sounds like not getting current

First thing to check is the battery on jeep. If the battery is low on power or dead,charge the battery or replace it with a new battery. It sounds like you are not getting enough voltage to the starter to turn it over and start the jeep. Once you get the jeep started use a volt meter to check the voltage at the battery. The alternator should be putting out 14 to 15 volts to the battery. Check the battery cables at the battery,clean and tighten if need be. If the alternator is not putting out the voltage as i described then replace it. Make sure the radio and a/c is turned off in jeep before you run your test. Hope this will help.

First check the battery you may have fried one of the cells this would have made the pop sound, take the battery out to have it checked at a parts store, Also do this check if the battery is good, with the lights on and heater fan on have an assistant turn the vehicle over while in the front to observe the headlights if they dim considerably it's a battery or starter if the lights don't dim there is a bad connection or bad starter solenoid or in line fuse link, follow the starter wire and check for the presence of bad connections or bad fuse link on starter and solenoid wires.

This could be a relay problem. (they appear to be a lot of the electrical problems with volvos.)
try twisting them gently while turning the ignition key.
You will locate them behind the ashtray, but in order to remove/replace them, you will need to remove the housing. 2 screws for the cigar lighter, and it will just 'pop off'.
good luck.

I just had this happen to mine the other day. In my case I had mine jumped but after a drive it around to make sure the battery was charged I had let it sit for 12 hours. I got in that night and it would not turn over. That that moment I knew the battery was not holding a charge. When I checked the battery I saw that I had the original factor battery. So after I changed out the battery I did not have any more problems.

Hope this helps

Sounds like you could have a bad battery/corrosion. The reason is your car was just fine until you turned it off. This means that the alternator was putting out the juice to run your car with no help from the battery. This indicates a good alternator but a battery that is no longer holding a charge. Take it to Autozone, Pepboyz, etc and have the battery tested.

If you have a voltmeter handy, put it on the alt and on the frame of the car or engine block to test for voltage output. If it's 14v then you got yourself a most likely bad battery or check for corrosion on both ends of your battery cables.
