I am having trouble with my left turn signal. Let me detail; ground tested and is good, replaced , replaced column switch, new relays, new bulbs, swapped housings from left to right, new fuses. noticed that when I clicked the emergency flashers it blew that fuse. Right works fine, the left turn filament is very dim and the read does not do anything. I have spent two weeks trying to track this down. I have built entire harnesses for vintage race cars and this has me baffled. Please help! Thanks, Jeff

There’s a possibility the TS switch has a short inside.
To verify; remove the switch. Test from the bottom. There are 2 rows of round terminals. One row for turn signals, the other row for parking lights. The center terminal of each row is power in; the terminals to the right and left of center correspond to the left or right signals. To test: put one MM probe on a center terminal, move the switch handle to left or right and see if there is continuity. If you get continuity for both sets of terminals, the switch is ok.
