I have a 1997 F150 4.6 . I have a new battery and a new starter on this truck.I put on new battery cable ends both cables. Cleaned grounds, as you turn the key to start, the starter motor starts to turn over but it won't and the amp gauge goes to zero.

 

CAN U HEAR STARTER CLICK IF SO MAKE SURE ENGINE ISN'T LOCKED UP,IF STARTER DOSEN'T CLICK CHECK STARTER SOLENOID
