Chgeck for a short by installing a AMP meter at the neg battery terminal, if you have two batteries take one out of the system. After installing meter, with key off see if you have a draw, a small draw of .05 amps is ok, just the memory in the system. If you have a daw check components by disconnecting them ie... the alt. the glow plug and so on. Make sure both batteries are good one can draw down the other

Has new battery and alternater but next day the battery dead


The battery and or alternator maybe defective, even new parts can be defective, look into getting the alternator and battery checked, if they are good, than you have some other electrical problem, maybe parasitic draw.

Truck is draining charge and not charging battiers


I just went thru same thing with my 2003 f-350 diesel. I hooked up my horse Trailor and drove to Von's parked went in came back out and truck was dead. I tried to jump it didn't work. Then over next two hours two tow truck Drivers hooked up to both batteries full power charge direct to my truck and would not start.
End story required two new batteries alternator and cilanoid discussed above. In other post. Also contributing to the cause was really badly coroded cables they looked good at the connection point but wher discovered to be coroded inside the tubing just above the end connections so bow it has all been replaced and I have had no trouble since. Hope this helps. Tanya

Replaced starter, alternater and battery car still drains battery. whats wrong?


First you can not test an alternator by disconnecting the battery cable. That is what we did back when cars had generators. Today you can fry the computer and alternator running the engine with the battery cable off.
Meanwhile, I would look for a fuseable link or main fuse problem. The alternator circuit may not be connected to the fuse box and battery.

Not charging


First tell me why you don't think it's charging.
Because of the voltage reading you are getting at the battery terminals? The range you want is between 13.6v to 14.2v. The higher the voltage the lower the amps. and true the other way, the lower the voltage the higher the amps. If you get a reading of 13.6v or lower, the alt is nearing or at max output. An alt can only run at maximum for around fifteen minutes and it will start slinging solder from overheating. It's a good indication the battery is either totally dead or junk. Charging above 14.2 the alternater is running wide open and is only putting out high volts which will cause the battery to boil , in turn destroying it. This is a bad alternater. All alternaters have integrated voltage regulater with the exception of ver few of the earlier ones. You cannot test an alternater by removing a battery cable to see if the engine keeps running without taking great risk of damaging the alt, regulator. So tell me why you feel it isn't charging. Remember an alt is not made to charge dead batteries. Their sole function is to maintain the battery charge. Without a battery, the alt won't last 10 seconds.
Hope to hear from you and good luck.

sounds like alternater, is on its way out, if it is not charging or over charging, it can drain your battery dead.
