Hi, all, my little car have no electric power and the battery is drained if I don't drive it for several days. Battery replacement doesn't solve the problem. Is it because it is aged and have to be often charged on high way? Does someone have any suggestion?
Thanks! Jing
Usually a parasitic load from the glovebox, underhood or trunk light on the GM's...make sure that or a map light isn't that problem...close them slowly and verify the light goes out...
If you don't find anything, you'll have to do a parasitic load test by running a test light between the battery and a disconnected cable, and pull fuses until the light dims (a small amount of load to the ECM and Radio is normal), then check the manual to see what's on that circuit and check all the items until you find what's staying on...
Put an ammeter on the battery, or just put a light bulb in series with the battery so you can see that it's draining. Go to the fuse box and start pulling fuses until you find which circuit is draining the battery. Then go look at what is on that circuit.
You need to identify where the problem is, then fix it. Things break. When they break, you fix them.
