2003 ford ranger 4wd 4.0l automatic, wont start. Clicking sound (0ne click) only. New battery With 12.6-12.8 volts standing charge, drops to about 11.5 or below when attempting to start, but recovers back to 12.5 shortly thereafter. Fuse to starter is okay. Starter relay was exchanged with another relay and seems to be a good relay. I jumped pin#30 and #87 on that relay and only clicked again. Starter taken off and benched checked. Both solenoid and motor worked fine. Taken to autozone and had them check it out, and passed. I bought a neutral safety switch, and a starter switch and installed both with no results. I even checked to see if by chance the engine seized, but I was able to turn the crank with a breaker bar with little resistance.I have 12.6v at the power side of the starter, but only a surge of about 6to8v at the service side for less the a second when my wife turns the key to start. I can't think of any thing else that would cause it to not start. I don't know the amount of volts the service side (small wire) at the starter should normally have and for how long. I'm sure this is the problem but I don't know how to proceed from here.
