Question

My new battery on my 79 300 sd mercdes benz discharge most time if not run for 3-4 days,help me

Answer 1

have the alternator checked on it and also have the battery checked,if both check good then you have a small draw on the battery somewhere in the car,any shop can run a draw check on it to see if this is the case and they can usually find it and repair it ,anything that stays on in the car will cause this,you probably just have a battery going bad,a bad alternator would drain it in less than a day,good luck on it,

Answer 2

To check if it is the battery take the positive lead off and let sit 4or5 days.Or take the lead off and check the cable for gnd. with a meter(most likely cause).Then trace the gnd. down,
