I had a similar issue. Battery was brand new red optima and charged full. Starter solenoid clicked rapidly when key was turned or connected directly
to battery positive terminal. Solved it by adding a 4 gauge black wire from
the fender side to one of the starter bolts, 24" long. Before it was added I
had a 6 gauge lawn & garden wire connecting the fender side to the front
of the engine block, but that didn't help. The small wire may have broken
inside, or may be too thin. The 4 gauge did the trick, of course you must
clean the contact points. Starts every time now.
