I have a first gen Cummins and I have replaced the alternator, external regulator, grid heater selinoids, battery, starter, battery cable from starter to battery, fuses. It pulls down in no pattern and sucks juice in a pattern of on off on off every few seconds and then it will quit. It also charges eleven to fifteen volts and sometimes charges one or the other for a long period of time and then when it is steady for a while the battery guage bounces very slitely constantly when the truck pulls down. I have unhooked the grid heater and it still does it. Any help would be appreciated thankyou. Battery does not go dead just boils if I rir it at 18 volts
