Ugh...I keep burning Turn Signal Switches
I thought I had this problem licked but it keeps coming back. As mentioned in the subject line, I keep burning through turn signal switches and I can't figure out why. First off, its on a 65 Coupe with stock wiring which I replaced two years ago with new Alloy Metal harness' from NPD (Main Harness and Tail light). Every time I replace the TS Switch, everything works fine for a few months then out of nowhere the right brake light will stop working followed by the turn signals and I'll see smoke come from behind the steering wheel. I originally thought the problem came from the right tail light connection itself because when I first noticed the issue, I jiggled the connection and it worked for a split second then stopped and I saw the smoke from the behind the steering wheel. Since that time I replaced the tail light buckets as well as the connector type, from the socket plug to the two wire pigtail. Everything was working fine until this weekend when I was installing a new steering wheel boom it blew again. I'm tired of blowing money on these things and thinking I got a cheap defective one and the next one will be the one that works/lasts. It's time to get in there and figure out whats going on. This last one, I took apart a can can see where the short happened, my question to you guys; is this happening at the turn signal itself or a result of something else in the system. If so where should I start?
Just to add to this, looks like the short is happening between the orange Blue (right Tail light #5 on Wiring schematic) and the blue flasher wire.
