Question Strange rear light problem on 94 Haritage

Hope I can explain this clear.

Lights on ,The only light that is lit on the rear is the lower fender marker light.

Amber lights dont light but the turn signals do work. Front ambers are on and than flash when signal is on. This is normal, but the rear signal lights only display when flasher is on .

Rear brake light works when front brake is engaged but does not when rear brake is engaged.
Rear tail marker light does not work although the lower fender one does.

To me I have power to the rear brake or the light wouldnt come on when the front brake is pulled in. I would asume rear brake switch but I have no marker lights . So this is got me baffled.

Any ideas here what I should be looking for before I start pissin around?
I was going to seperate the conector under the seat and do a test there of all light circuits before going back to the rear lights.

Start following the wires to make sure that nothing got pinched, or tire worn.

The rear directionals, are only rear directionals. They are not marker lights like the front.

I kida figured that as there is only one wire a side in the back and I belive 3 at the front.

I can see the wire to the tail light marker light being screwed but the fact that the brake light works from the front brake only. Thats 2 seperate lines messed
I have a manual for my 97 so wonder how much different the rear wiring would be.

If ur saying that the problem is when applying the rear break.. than u should start from there... test the rear brak switch for continuity when pedal is pressed, if it works, than move up the line to see what's troubling. I have the manual with a wiring diagram for softails from that year, clymers manual, but I can scan the diagram maybe during the weekend... early saturday I can have it scanned... as for now, that's what I can think off.

I have a different problem, rear brake light won't shut off, I tested for continuity in the rear brake switch and there's my problem... might be the opposite with u

I thought it might be the rears brake switch BUT!! I also have no marker light in the tail light, only in the lower light on the rear fender. So because I have 2 different isues, I cant see the marker lights tied to the brake light switch unless they both share the same ground, Than again if so why does the marker in the fender work.

Something tells me its inside the rear fender light itself.

Not being a smart *** but... Have you checked the bulb.It could be the filiment for the running light is bad. And my money is on the rear brake switch for the other problem,I think its 2 seperate problems.IT could also be that the switch is corroded where it plugs on.

This seems like a good place to start from.

it's all a common ground, so if the ground would be the problem, the brake shouldn't light up with the front brake applied

I know that, I was refering to the lights themselves sharing one ground or if the brake had its own ground and the marked having there own ground as well.
Anyways I know what to look for. I just thought it really odd that a switch for the brake would die the same time the marker light would die as well. 2 seperate systems. Was only curious if by chance somhow there linked in any way as to fale together and at the same time. coincidental!!!! or what!!!!!
