1994 Ford Bronco Will not crank

There is a solinoid on the passengers fender the battery cable connects to one side the oppisite side connects to the starter cable. There will be one or two small post on the front of the sol run a wire from the pos post on the batt. To the post on the sol if the truck cranks sol is ok check wire that plugs to that post use test light hold key on crank position light should light up. Hope this helps billymac
