Question:
I have a 1999 Ford Expedition...battery won't hold charge, yet new batteries drain and alternator checks out as okay...replaced connections, can't find problem. Could it be the physical wire going from the alt. to the batt.? I've heard these wires are an integral wire to the harness, so not easily replaced and expensive, is this true? Any advice would be greatly appreciated. ;)

yes........it seams anything to do with electrical wiring is expensive......but there are things you can do to isolate the problem...........all you need is a 12v.test probe & the help of a friend..............have your friend disconect the neg.batt.terminal & connect the probe between......it should glow a little.........thats your on board computer & programed radio sucking up juice.....but on yours....it is probobly glowing bright...........then you remove fuses from the fuse block.....one at a time...so you can identify the problem circuit....youll know when the test light sudenly glows less...............good luck!.......oh bye the way make sure all controls & switchs are off.....even an open door will cause the interior light to stay on.I have a stain on my car, and every claner I use doesn't work, does any one have any sugestions?
about the only thing you can do is take the positive terminal off and just touch it to the battery post with the key off and see if you get a spark and if you do you have something draining the battery, start pulling 1 fuse at a time in the fuse box and go back and recheck to see if you still get a spark when you take the battery cable and touch the battery terminal with it and keep repeating the process until you find the circuit that when the fuse is pulled stops the sparking.everything slip said, but pull the radio fuse out first to get rid of that draw then continue.
ok nom if your charging filter caps the whole time then youll never get rid of your amp draw. you just contradicted yourself
he was saying youll see a draw its your radio and computer but if you want to get technical about it and if he wants to use a multimeter then you should not see more than 30MA draw on the negative battery post to negative battery cable, anything over that is not just your radio or computer.
What can you do to stop your drive belts from making noise ?
Don't listen to these hicks. You always get a spark when you touch the cable to the battery because you're charging filter caps in several devices. It doesn't mean anything. A 12 Volt probe isn't going to tell you anything either. You need to put an amp meter in series with the batter cable and then start disconnecting stuff and pulling fuses until the current draw goes away. It's not the wire to the alternator.More Questions & Answers ...
