Electrical problem
1997 Ford F150 V8 Two Wheel Drive Automatic

truck was clicking from starter and not starting, removed starter and got it checked. Ok. Took battery toget tested and needed replaced. Done, started and ran a few days then clicked again. Jumped and it started. Ran another few days now it wont start. Tried to jump but nothing but a single click from solenoid. Battery in dash display says full battery. Could solenoid be the problem?Dont think its the altenator cuz all lights and electrical have full power. Help!

STARTER LOAD TEST
Connect starter load tester and voltmeter to battery terminals. Ensure no current is flowing through the ammeter and carbon pile of tester. Disconnect terminal "S" of starter relay. See Fig. 1 .
Connect remote starter switch between terminal "S" and positive battery terminal. Ensure transmission is in Park on A/T models, or Neutral on M/T models.
Crank engine with ignition off. Note voltmeter indication, then stop cranking engine. Adjust carbon pile to match voltage obtained while cranking. Read ammeter. Replace or repair starter if current exceeds specification. See STARTER SPECIFICATIONS .

STARTER CIRCUIT VOLTAGE DROP TEST
NOTE:If starter cranks slowly and battery is okay, perform following test.

Check engine ground strap and negative battery cable connections and repair as necessary. Prevent engine from starting by disabling ignition system. Ensure transmission is in Park or Neutral. Connect remote control starter switch between starter solenoid "S" terminal and positive battery terminal. See Fig. 1 .
Connect voltmeter positive lead to positive battery terminal. Connect voltmeter negative lead to "M" terminal on starter solenoid. See Fig. 1 . Crank engine using remote starter switch while observing voltmeter. If voltmeter reads greater than 0.5 volt, go to next step. If voltmeter reading is less than 0.5 volt, starter feed circuit is okay, repair or replace starter.
Move voltmeter negative lead to "B" terminal on starter solenoid. Crank engine and record voltmeter reading. If voltmeter reading is still greater than 0.5 volt, excessive resistance is present in positive battery cable or cable connections. If voltmeter reads less than 0.5 volt at "B" terminal, check cable connections at starter solenoid. If okay, replace starter solenoid.
