Left blinker not working on 19ft 1979 bigfoot

[theburro]

checking my lights before I head out next week, and I noticed that the left bliker isn't working. I just bought the trailer 2 months ago, and I've been getting it road worthy. Hoping to head out on Friday so any help would be great. I decided to change the tail lights with new ones as the old ones were cracked anyway.

Here's what I know

on the left side there are green yellow and red.

Yellow is ground, green is daylights running lights and they work fine.
When I check the voltage on the red one with the blinker going and not plugged in it alternates the voltage. when I touch the wire to the one it is supposed to be on the the new light, the voltage reader does not register anything while the blinker is on.

On the right side everything works, blinker and daylights.

It has yellow green and brown I believe and the voltages read the same as the left side.

Any help would be appreciated.

Thanks,
Lowell

Did you check your blinker fluid?

Electrical troubleshooting, always always always check your grounds first.

The ground should be good, as the running lights work, and it's the same ground.

Just because the running lights work, doesn't mean the ground isn't at fault. When I recently picked up my '72 Compact Jr, the running lights worked just fine, but the turn signals wouldn't. Same ground, same circuit. When I cleaned up the ground connections and rewired them, it worked fine.

But anyway, good luck figuring yours out.
