I replaced my battery, and the lights and other electrical all worked but the engine will not turn over. Factory alarm (a clicking noise since I disconnected the alarm horn) goes off when I put the key in the ignition. No clicking sounds from the starter solenoid (which might be poor quality or corroded cables). Ran fine before dead car battery. Key fobs also have dead batteries. Who can help? Internet search...

YES!!! This is a working solution for 2002 Ford trucks.
mine: 2002 F150 King Ranch, 150k, all stock, only one battery.
Many Thanks to this forum, cheezit, and
