Joe thanks for the photos. I actually have re-wired one before. I soldered the ends. I am going to re-do one today that has obviously been messed with before. I opened it up and one of the wires is fried and it's due to it having been re-wired incorrectly. I thought so when I saw it but ran to the computer to search out the wiring pattern since I remembered it differently from what I saw inside the block.
Good photos! Now off to tear this down and clean the contacts before I grab up some new wire.
