How long have u got to charge it for for 1st use because I charge it all day when I turn it on the next day the battery kept going down I'm still charging it


A new battery comes charged well enough to start the car, if it keeps going flat u have a problem either with the charging system or a power drain, so once car is turned off sonthing is staying on draing the battery. Or the battery could be faulty but very unlikely. To check the charging start car and put a volt meter on the terminals of the battery should be reading aprox 14.2 v if it only reads 12 something then u have a charging fault. If charging fine then have to test for a power drain and the easiest way to do that is to open bonnet or boot depend where battery is lock the vehicle up and wait about 20 mins for the car to shut down Ecus etc remove earth terminal off battery and put a 12v bulb from the earth terminal of battery and the earth lead if the light shines u have a power drain remove each fuse in turn remember to put it back after until light goes out then u have the offending circuit. Hope this helps

After 2 days the battery dies what is the problem


if the vehicle is being run for two days and the battery goes down, it could be a charging system problem, if the vehicle is not driven in two days and the battery goes down, try having the battery disconnected from the cables while the vehicle sits for two days, if the battery goes down, it is the battery and if the battery holds a good charge , it is an electrical problem.

Car sat for two years there is no spark and i can't hear the fuel pump working what other problems could i have ( installed a new ignition coil)


So you have no crank no start correct?
Battery must be fully charged ( three day charge) or new.Make sure battery cables are clean and tight.
Use meter and make sure B+ making it to starter .
If B+ not at starter then check cable to starter and neutral safety switch and ignition switch.

This is for crank no start

B+ goes from battery to Ignition switch to coil to switching device( ignition module) to plug.
use a volt meter and find out where B+ stops.

I have a renault clio 1.4 sport x reg. ive always had a slight problem with it starting up frst time put it down to being old. however recently i have had major problems with it at first it seemed like the...


OK your problem is the Alternator isent charging the battery How to check it is to charge battrty first and then start the engine and turn on the head lights Noe see how bright they are and with lights still on turn off the engine Do the lights stay the same or go dim .
Now with lights still on start engine again and watch the h/lights Do the brighten up if no then turn all off and your answer is the alternator needs either replacing or change over as the battery is a 12 volt and the alternator charges at 13.5 volts AC current but the car is DC but the alternator changes the voltage to DC automaticly.
Let me know how you get on with it Ron
