Ok, I know someone can help me here, I've seen this before but forgot the fix. Battery is full charge, when I crank the Starter Solenoid on the fender wall "clatters" but the engine doesnt turn over. When I jump the battery terminal to the S terminal, I get the same thing, clatter but no engine crank. Tried it hooked up to another car with jumper cables too and still get the clattering but no engine turn over. Help!
