ok u have a new batt, make sure that the terminals are covered with distilled water.<br> <br> get a jumper and take it straight to the mecanic.<br> <br> get them to test the output of the altenator should be around 30 to 35<br> <br> it weired but about 3 weeks ago, after about 3hrs of coninueous driving, i stoped the car to check the post box and the batt was dead flat. starter didnt even flinch. had the output of the altenator checked it was fine.<br> didnt get the batt charged just drove it for about 20mins no problems since.<br> <br> it is a freak thing but a batt can go dead flat if there is a lot of static in the air or if lightning hitst the car.<br> <br> one other poss could be the glow plugs are comming onn without you knowing.<br> <br> while your driving- keep lookinh down to see ig the light may come on<br> <br> when the key is in the first position - that they arnt comming on then<br> <br> when starting the car- that they do not stay on for too long<br> <br> the glowing process takes alot of power, if you are driving and the altenator is sending the batt a max of 35amp and the glow plugs come on at 70amp there isnt any chance of keeping up with demand. the batt would go falt in a matter of minutes.<br> <br> also , if u have the head lights, the aircon to the max, the cooling fan on, the radio and cd playing and demister, all on at once it can amount to about 5amps of draniage which means you are using all power comming from the altinator plus any stored in the batt. can take an hour or so to flatten the batt that way.<br> <br> some poss reasions.<br> <br> good luck <br> <br> louis
