Question about 2002 Ford F350 Super Duty DRW Reg. Cab
Sounds like the battery cables have corrosion inside the insulation (causing high resistance ) but have the Batteries tested FIRST The batteries must be checked and fully charged or a bad cell in 1 battery will drain the other battery causing low voltage and amperage . They have to be checked individually ! This system has dual batteries in series for 12 volts inturn requires high amperage to operate the glow plugs , controller , computer . Follow the positive cable from the passenger side to the drivers side look for corrosion at the battery terminials these models have the circular squeeze type clamps unless replaced ( you can find this by feeling the battery cables after trying to crank the engine becareful the high resistance areas will be warm or very hot ) the most likely places are right at the battery terminals if you are'nt sure about the battery cables,, simply peel the insulation back from the cable ends and inspect the the inner wires .
Hope this helps ,
