OK folks, I tested the wires at the starter, and I am getting 11.5 v. So I am assuming that the solenoid is good? Disassembled the starter, and cleaned and inspected the brushes. They look good to me. I sprayed the whole thing with electric cleaner, put a bit of oil on the shaft at both ends, and reassembled it. Tested it to be sure it was functional, and that's where I stand now.
Any ideas? This has me a lot confused.
Thanks
