Unplug the electrical connection and remove the two bolts holding it. Reverse order to install.
To hookup the solenoid switch on F150 pick-up 5.0 after replacing it, first connect a voltmeter or test light to the solenoid's S terminal. Make sure the starter receives voltage at that terminal when the ignition switch is in the on position.
it will be a silver box 3 to 4 inches square with a wide flat plug either bolted to the firewall or one of the fenders
alternator probably needs replacing not charging battery or bat is dead and not taking charge
What question
They might have a different internal voltage regulator that is used.The idiot light in some systems acts as a resistance that makes the regulator to charge.try putting a small automotive bulb in series with regulator connection at the alternator and see if your gague reads any voltage then.Check a motor manual to define the correct connection post.
I believe it is built into the altenator.
window regulator cable is broken need new regulator
