No right turn signal

[Danish Farmer]

I lost the right turn signals. Only the rear will flash at half power. The other ones got no electric power to them.
Inside:
--On the dash the right turn indicator does not light up
--The relay will tick like normal
--The voltage guage will move into the red zone at every click
--It will blow fuse after a while. The hazard too

Left turn signals are perfect and the light in the dash as well

Do you have any hints for my trouble shooting ?

Look for a short to ground in your right turn signals. Sounds like you have a short somewhere up front since you say you have no power there.

What happens when 4 way flashers are on?

Inspect the bulb connection on the front for jumping the two connections. While bulb is out try it to see
If it pops fuse, this will tell you if it what part of circuit is shorted.

Thank you for advice. Four way flashers blows the fuse right after pressing the switch. I disconnected all bulbs and started checking for power at the connections while the truck was set to flash to the right. After one minut a light fog was coming up from the dash and things were warming up around the four way flasher switch.
I reckon the black thing with the 4way flasher button on it needs replacement.. or do I want to check other things before getting an order shipped from over seas ?

You need to identify the short before ordering parts. Trace the wire disconnect at "the black thing" and see of short is there. Smoke or fog is a bad thing, did you put in a larger fuse, it should just blow the fuse before smoking anything.

Sure sounds like a short right at or near the 4 way switch. Could be a wire or terminal at the switch.

The smoke from the switch is simply because that was the source of the most resistance and the easiest place for it to heat up. You most likely hurt the switch because of a short, but I doubt the switch was your short.

Finally my mechanic got things sorted out. There were two things wrong. In the inner fender om the right side, a positive wire to the turn signal was rubbing aginst some metal. And the electric plug for trailer light was erroded on the back side, making possible problems too.
Thank for your help
