Signals OUT Again!!!!!!!!

I now have E.Flashers, Tails, Brakes, but no signals. When I test the wire to the flasher, I get erratic behavior.......a good positive on the black side, but when I plug in the flasher, I get a dim positive on the red side.....turn on the flasher, and it tries to work, but poops out on the second or third try...then loses it's hot connection..........

The car starts OK, runs OK........As I said, I changed the neutral safety switch after the problem started.......it doubles as the back up light switch......that circuit is tied together with the turns on down the line.......If the switch isn't the problem, it seems it would have to be a wire coming INTO the power block on the firewall, or going OUT of the same into the car......be that as it may, I cannot find a THING that has burned in there.......

I'll check the amp guage connection in a bit here.....don't know if it's in the same circuit.....the smoke was kinda putrid.......

Just bugs me that there is no sign of heat anywhere..................
