54 Convertible Turn Signal Issues

Good day!

I’m seeking the forum’s help in deciphering a turn signal issue. In reading other similar posts, I suspect there is a ground or resistance issue, but I have a mixed bag of functionality so I’d like to ask for the view of this group of experts!

1. When head lights or parking lights are OFF, I have front turn signals on right and left. The left rear turn signal works, but not the right. Flashing ‘speed’ is faster than I would expect it to be, but is not as fast as if a bulb is out. Dash indicator lights both flash at the same time regardless of whither right or left indicator is selected. Dash indicator lights are very dim.

2. When head lights or just parking lights are ON, I have front turn signals, but NO rear turn signals on either side. Flashing ‘speed’ is slower than described in #1 above. Dash indicator lights function as described in #1 above. All other tail lights illuminate as expected.

I have checked all bulbs visually and functionally to make sure there are no broken filaments. I have cleaned sockets, contacts on wires and bulbs, the interface between the socket housing and the taillight opening and cleaned what I believe to be the ground connections for the rear lights. I have checked continuity and all circuits appear to be intact.

Your thoughts/opinions are appreciated.

Thanks much!
