As above help needed on my dads car its a 4x4 sapphire cosworth and the battery keeps going flat on him it has got a new battery on the car if he use the car every day it does not go flat but as he only use the car at the weekend i was just asking incase any one as had this problem before as it is doing my head in


Thanks for any help on this

 

Mmmm had a simalar problem about 2 times and most recently on my 3 door , all times its been at my alternator , theres a blue wire goes ont a thread , shouldbe the same colour i think on yours , anyway i think this sends a signal to the battery to charge it ? i might be wrong , but 99% sure , anyway had this type of problem recently and checked it out the other week and mines was all split and corroded , got new connector , redone the connection and shes been great since , bought a new battery too before finding this

Maybe even worth cleaning it up just incase , even if it looks ok

 

Sounds like its not holding its charge? Try and change the alternator, check connections on the coil also

 

Mine also does it

I just think its my alarm draining it.

Steve.

 

Both mine drain too, mostly the alarms but a trickle charge for 24 hours and back to normal

 

Do go changing anything until you have done some proper tests. Have a look at this:

Volt drop your alternator and do an amps draw test on your batery.

ONCE AGAIN THANKS FOR THE HELP
