1997 Ford F150 6 cyl Two Wheel Drive Manual 137000 miles
New battery will not charge. New alt/reg did not solve problem. During testing, grounding the regulator proved 18 volts from alternator. New regulator and known good regulator all act the same.
At one point, grounding the regulator would make the system work properly until engine was shut down. This no longer happens.
Followed testing procedures laid out in Haynes manual and everything says replace regulator. Does not fix problem
have the same problem?
