Winnebago, F53 Dim Low Beams only
We have a Winnebago Sightseer on a Ford F53 chassis. It has a four sealed beam headlamp system with H4651 single filament halogen hi-beams and H4656 dual filament combination halogen high/low beams. I...

I also have a F53 but Chevy P series also have the same issue. I just build a new wiring harness and hooked up to the battery and use relays to control the power, using the same switches inside to hook up to the relays. If low current due to wire size this will help you.....

You most likely have a poor ground for the headlight circuit. The easiest way to find out is to disconnect the plug and follow the wire to the ground stud. The ground studs are generally welded to the frame or a frame support member. They are rarely if ever painted or otherwise coated after welding so they rust rather quickly. The rust acts as an insulator, reducing the current flow.
If you can't easily find the ground stud push another wire into the ground terminal on the socket and run it directly to the negative post of the battery. If you have an improvement in the light output you'll know what needs to be done....
Thanks. I normally try to respond, let people know if I've tried their solutions, and not leave the thread hanging but wet weather has kept me from tackling this. I wanted to solve this before a big trip next week but, in California, I won't complain about the rain and snow.
As I noted in my original post, I've considered both of these issues...poor ground AND an inadequate wiring harness. In fact, I had almost pulled the trigger on an aftermarket upgraded harness and relay kit at the time I got the headlights. I'm going to do it, and soon, but don't know if I will have time before this trip.
In the meantime, I'll at least have time to chase down possible ground issues AND, remove the spaghetti of extraneous wiring left in the dash and under the hood by the previous owner. Some of this may be part of the problem as well. I don't need the FM modulator since I'm installing a proper stereo with proper auxiliary inputs. I don't need the Audio/Video modulator since I already jerked out the old CRT TV's and installed flat screens with proper digital tuners and HDMI inputs. I certainly don't need the multitude of dead end wires he had hooked up to Lord knows what. (shaking my head at some of what I've seen.)
I will let everyone know how this turns out.
