Dead batteries again!!!!!?
Ok so I've had battery problems for weeks now I was having problems with the batteries dying I my truck set overnight well come to find out the voltage regulator on the alternator was bad and somehow I made it back from Tennessee after this happened by jumpin it off and hitting the road.. Got home put a new alternator and batteries in... The truck ran great for about 2 days then started running-idling rough until warm so I knew I messed the ficm up so I took it off did the fix myself at work yesterday but I didn't unhook the batteries before I took it off and I put the fixed module back on 2 days later and the batteries were dead as crap? Could me not unhooking the batteries caused this? I jumped it off and it ran great.... Funny thing though my alternator was warm to the touch after sitting all day? Could the switch be bad? Idk I've tried everything
