1999f-150 battery goes dead if I leave battery connected I check find a short I checked for shorts but could not this by unconnecting battery ground

The procedure for finding this problem there is a short some where, if not lit I’m stumped— If it is lit remove the fuses one at a time, when the light goes out that is the circuit that has the load— Once it is narrowed down it is usually easier to find the problem— there are circuits that are not fused on newer vehicals and wires before the fuses can also be the problem. If it is in the charge start run circuit it may be difficult to find and if found difficult to fix. Oh I almost forgot, you will have to disconnect the radio and any alarm is to remove the positive test light between the positive on the battery— make sure every thing is cable clamp and hook a cable and the positive post off— if the light is lit (always on circuits)
