Rooster,
I just went through the same problem. My solenoid would just click but the starter wouldn't engage, sounds like the bendix needs a little grease/oil. Is the starter turning but the bendix won't engage? Just my thoughts.
NO grease, better with a light oil ( light oil only, NO WD-40, Crc5-56, Crc6-36 or other spray lube ) .Should have used grease.
