Thanks for the help. Cut the 330's and flashers working. Played around and with LED's the back flashers worked again as before. Playing with #6 got a faint glow, so think the socket is bad...will try to clean it and see what happens. Pretty sure #4 is a solder issue. I stink at soldering and after 3 tries have failed. So, perhaps this weekend I will just take the time and do some soldering practice on some spare wires. Moving too fast for my skill level. But enjoying it. It's an addiction I never saw coming. Thanks for all the help. Will check back in when I have an update.
