So one day I started my car slid my automatic shift lever to D4 and the light on in the gauges didnt light up the rest do light 1,2,D2,D3 but D4 not .Then it kille the battery thought it was alternator turn out it wasnt .....help plz
First of all never ever pull the battery cable off when the engine is running, if you do it could cause a voltage spike and fry your electronics. I had a customer that did that on his late model crown vic and it wound up costing a bunch of money to get it all fixed. Now on to your problem, you will need a good battery so have your recharged and tested to make sure it can do the job, now put the keys in your pocket, make sure all of the doors are closed and no light are on, disconnect the negative battery cable, but a test light between the cable and the battery, if the light turn on then you have a battery draw, now you have to eliminate circuits one at a time, of course the first one is the alternator, disconnect it completely, check the light if it is still on then you will have to remove all of the fuses one at a time, make sure you make a note of the location of each fuse, keep going until the light goes out, when it does that is the circuit to trace out, once you have found and repaired the draw start replacing fuses one at a time checking the light each time, finally reconnect the alternator, if no more light then no more draws. As far as the D4 light it may just be a bad bulb in the cluster or the selector switch on the lever not making contact in the D4 position. HTH
ok so when I put the test light on between the cable and battery does it matter if on the negative or positive side?
Nope one or the other.
