Trailer wiring problem

[Zen]

Hi,k have a 2000 f250 and I am getting power to the left hand trailer turn signal. No power to the right hand turn signal. I have traced it as far as the fuse block under the hood. Left hand gets 12 volts;. right hand gets .06 volts.

Any ideas on where the break might be or if there is a relay that controls this?

Thanks

Update - I am missing the two relays next to the PDB for battery charge and backup lights. What part or type of relay do I use there? Just the same as the other relays in the power distribution box?

Bump

I have read that it might be the actual flasher relay. Where can I find a whiring diagram?

Thanks

or a wiring diagram

Anyone?

These crickets are getting anoying

All relays and fuses have been checked. It is either the relay or a wiring corrosion/short issue. Can anyone help out with a diagram.

Thanks

Turn your flashers on and see if it works then. If it does not then your flasher relay is most likely bad.

All flashers work except for the right rear on the trailer. No flasher and no break light. Running light only.

Where is the flasher located?

Have the under-hood fuses been looked at? I think each side is fused separately. My left trailer signal seems to not like U-haul trailers... keeps blowing that one fuse!

All fuses have been checked and are good.

Ok so your right side truck flasher is working. If that is the case then flasher relay is good.

Yep, everything works excpet the right side trailer.

the only reason I brought up the flasher relay is I saw a mention of it in a web search, but can't find it now.

I have 12 volts at the #1 fuse inside the cab for all lights.
12 volts at the #1 fuse under the hood
.06 volts for #3 flasher under the hood (right side)

Need help with which wires to trace and where they go to find where the bad connection or corrosion is I am guessing.
