My battery be drained

(I replaced the battery this morning, it doesn't change anything and it for some reason is draining the battery) Something draining the battery - you have a parasitic draw on the battery, like something is on but isn't. More than likely the instrument cluster is the problem. Silver solder migration on the circuit board inside the instrument cluster can cause a parasitic drain on the electrical system. Also, can short out the serial data network causing no start conditions.

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 yearsmust try this bitman and reliable-store. Both are good

Remove negative cable from battery, connect a test light to negative terminal, opposite end off light to negative battery post. ( let sit for 3 to 5 minutes). Then start pulling fuses, when the light goes out that's your bad circuit. God-Bless! Its worth a try.

Sounds as though there is a charging problem with the car. It starts when battery fully charged but when the charge is low it fails to start. I would get a mechanic to connect his meter to the battery and see if it is charging as it should. It is also possible that something is draining the battery when not in use. Check interior lights are going out when parked up, nothing is plugged into cigarette lighter outlets attached to sat nav etc., things like that.

I finally found a mechanic who found 3 broken wires. The diagnostic machine now reads the car and no faults were found. He changed the fuel pump and the car now cranks but doesnt fire up. I got fed up with the mechanic scratching his heading after 3 weeks sat in his garage so i got the car back home. I changed the battery cos the old one was completely knackered. I need to get this started asap... any suggestions? its a 1.9 diesel

it could be the radio wasn't hooked up right and doesn't turn off when the car is off. Or you could have a broken or chaffed wire somewhere grounding out. either one will drain a battery rather quickly.

When the battery was disconnected, the HVAC system lost its calibration or one of the door actuators is stuck. With truck on, set all HVAC controls and switches to their OFF or CCW positions. Disconnect the battery, wait about 3 minutes, then reconnect. Turn ignition to ON position, doesn't need to be started, and don't touch any of the HVAC controls for about 3 minutes. This should reset the calibration. If this does not work, a mechanic will need to diagnose the problem.

It could be the battery. Make sure you get the battery checked. Make sure it is not just charging but able to hold a load and doesn't drain. The other problem it could be is with the firing of your distributor. I had a problem with my chevy s-10 where it would start and then after driving and stoping for a brief period it would not start. Then after a long period it would start again. I change all my plugs and still had the same problem. I changed the spark plug wires and had the same problems. I had someone to look at it and they changed a part in the distributor that had rusted. I think it was the relay.

have your alternator checked that may be what is draining your battery and not letting your car start after it has died

Starter turning slowly sounds like:

- bad starter, or
- bad connection to starter, or
- bad connection(s) on starter relay, or
- low charge on battery, and
- and maybe some others... but these are most likely
