    I have same problem, I have went threw 2 alternators and 3 batteries. Not sure but will try this trouble shooting tomorrow.

    I have the same problem. My 2001 Monte drains in much the same way. I have on the other hand found that it is a problem with the radio or something that is relayed through the radio. I have that fuse pulled, and the drain has stopped It has a radio display system RDS so it controls the dome and headlights, horn alarm settings etc. So I haven't found the problem beyond that circuit. Does your car have an RDS radio? Any ideas???

    We found out it was the alarm. If the car is locked manually, the battery stays full. If locked with the fob, the battery will be dead in the morning. How to fix this??

9 times out of 10 it is the factory amplifier. I had this same problem and it was the amplifier. Disconnect the amp located in the trunk by the speakers and see if the drain continues. You will not have music, but having the amp replaced with an aftermarket one will solve this problem,

I had this problem too. I took it in and they came to the conclusion, after much trial and error, i took them a week, that it was the amp mounted under the back window.

You need to monitor the ground side of the battery with an ammeter.
The unwanted drain is probably within the (unfused) 10 Amp limit of most multimeters since even a 5 A drain would be enough to kill the battery overnight.
Do NOT start the car or turn on any other loads while you are doing this.

Detach the ground cable from the battery, insert the meter with the leads plugged into the 10 Amp. jacks found on most cheap meters, set the meter to that range, connect (with clip leads or some other secure method) the negative lead to the minus terminal of the battery, TAP the positive lead on the ground cable.
If you see that the 10 Amp range will not be exceeded, clip the lead to the clamp.
As long as the current isn't above the 10 Amp limit of the meter (will most likely be less) watch the meter as you pull and replace each fuse you can find.

If this doesn't show the faulty circuit, buzz me back and we'll go on from there.

    Wouldn't have seen any reply if you had responded sooner; our trusty system decided to eat its Windows installation and I have been crippled for over a week and still have a mess to clean up after restoring.



    Let me know how things go-

Some how the alternator doesn't charge the battery. Do a battery voltage check with both engine on and off, should be 12V ish off and over 13V on. You need to recheck your alternator replacement to see if it's correct, everything plugged in yes? All the wires and eye terminal bolted on? It is very likely that the alternator you changed not charging the battery at all that's why after 20min rolling on un-charged battery power it must go down.

Had to jump start two times now, they replaced battery now same thing again. dead nothing


Well, something seems to be draining your battery. Are any accessories left on? Too unusual to get a bad new battery. Get a load test done on the battery...will tell you if the battery is holding a charge. If it is fine, then the alternator might be faulty and would not charge the battery as you drive. Hope this helps. Worst case there is a short somewhere in the electrical system that is draining your battery.

sounds like your starter motor is at fault.I have had this problem before and found the starter was draining the battery due to a short in the windings of the motor.

sounds like you have a bad ground. There should be a motor ground on the back of the motor anas well as the battery ground. The battery going dead could be caused by this or a bad regulator in the altenator unplug the altenator to check this for the starting problem
