blueovalz Posted October 25, 2001 Share Posted October 25, 2001 I'm not good with hieroglyphics (my 12 year old daughter is though) but here goes: Your voltmeter (or VOM) would probably work fine, but you need it on the "dc amp" setting (if you have this), and not voltage. Start with the highest amp setting first, then work down to a useable range, as this will help prevent you from burning out the meter. With all your fuses in, you should read no amperage (except a very small amount for the electric clock and or to keep the radio tuner/clock set if you have an aftermarket radio). If you are reading a substantial current (my guess is anything over a couple of amps) then it looks like a ground is present on one of the circuits. With all the fuses out, there should be no current flowing. Look for changes with each fuse pulled. A big drop in current when a fuse is pulled indicates that circuit had a load on the battery, and should be investigated. With all fuses pulled, you should not have any current flowing at all (or the test light goes out). IF you have a bad cell in the battery, this may cause the battery to go bad regardless of the load. I would also suggest that both + and - wires be removed from the battery (making sure it has a good charge when you do this), leave it over night in the car, and the next day check to see if it is drained again. This will tell you the battery itself is bad. If the battery is still good, you've got some work ahead in finding the ground. Good luck Terry Quote Link to comment Share on other sites More sharing options...

blueovalz Posted October 26, 2001 Share Posted October 26, 2001 Well, if the ammeter is indeed showing current (ammeter is in series with the terminal and the lead), than you certainly do have a ground somewhere. Let us know what you find. Terry Quote Link to comment Share on other sites More sharing options...
