Hi folks i have a 91 Saph 4x4.Overnight the battery goes completely dead have to jump start it in the morning.Since this prob started last week ive noticed the heated front screen has stopped working too.During the day when im using the car the battery dont go flat.Its a new battery by the way.Any ideas?Thanks in advance guys.

 

does the charging light on the dash come on ?

does the blue wire connected to the alternator look OK ?

 

Looks ok mate yes

 

I'd check the charge rate next, the alternator even if charging perfectly can still be faulty, suffering from leaky diodes(one way electrical valves), so it being connected to the battery could be discharging the battery through the alternator, you could temporarily disconnect the battery one night and see if ok in the morning when re connected.

Thanks ive tryed that and battery was ok in morning when reconnected.I'll pop down to Bannings and get charge rate checked,thanks again.

 

Maybe worth a try and check how many current intensity is going from battery when ALL switches and receivers are OFF?
Put your keys off from ignition barrell, close the doors, turn off all switches and dissconect negative lead from batterry.
Then take a multimeter and check how many Ampers or miliAmpers is going between "-" terminal and disconnected cables. Take a lead "-" from multimeter to "-" terminal on batterry, and lead "+" from multimeter to the leads disconnected from batterry.
What You see on display?
Maybe have You any short circuit at instalation or any dimmer / relay is broken?
I have had this symphtom on Escos, when inner light relay was broken. This small unit draw current all time, and after a day my battery was flat.
cheers

check that the light in the boot ,is not on all the time when the booth is shut

 

Thanks guys will do.

 

Alternator is the most likely suspect.

The fact that the heated windscreen is not working, which only works when the engine is running, indicates that there is not a correct "engine-running" feed. This comes from the alternator.

 

Get a charger conditioner CTEK ones are good got some £75 put it on the saff and the battery lasts longer and always stick it on when i know i am going to use it the night before pm if yo want one got the £45 ones two

 

thanks

 

I had a similar problem on my cossie, my batt was draining after two days. Turned out it was the radio, the previous owner had put a cd player in and wired it direct to batt. My local autospark wired it back up to the factory wires and has been dead on since.

 

Thanks for that
