Reverse Polarity on rear bulbs

[Shugalou]

Something strange is going on when I went to replace a burnt out bulb in the rear. The signals stopped working and when I put the bulb in the wrong way the signal will work but when I seat it correctly it doesn't work.

I will be checking grounds in a few minutes but wondering if anyone else have insight into this.

Everything worked fine before the I tightening some bed bolts...Hoping it's an easy find/fix.

Thanks

So after more inspecting around the front signals no longer work. I'll be searching this site for some guidance.

Flasher unit isn't making any noise so I will start there....I have replaced this about a year ago but we'll see if this fixes the issue.

Problem solved...turned out it was the flasher unit. I swapped out the hazard flasher and everything works. The one socket is kinda loose but after some shaking around it's working.

I'm looking to use the old lights for a few months than switch to LEDs
