It's gotten to the point that a new-to-me vehicle gets its charging system worked over, first thing. The Exploder didn't pass and I ended up replacing both battery cables (voltage drop on cranking). Emissions tests sure work better that way....
i'll be damned,battery cables?i've been chasing grounds all around this thing while waiting for the ford tech manuals to get here.the original cables are on it and look ok,any idea what the risistance should be through factory cables?
