2008 f250 5.4 shut off while driving
While driving up hill at 60mph the engine gradually
lost power. The truck shifted gears at 55mph and
ran at high rpm like normal but still losing power
until eventually the motor shut off. When I tried to
restart I just get one click from the solenoid. Radio,
lights, ect all working fine. Checked battery and
had 12.1 volts with key off. When turning the key to
start position it went down to 8 volts. Had the truck
towed home. Today I swapped the battery with one
on my other truck, same thing. Solenoid click.
Trying to figure out where to start
