Some time ago there was an article about dash turn signal lights fizzing out due to a bad ground. It said to add a ground wire to one of the flasher terminal's but But I don't remember which of the three terminals to attach it. Tung Sol 535 X, L or P. I think it's P. Anyone remember this or has the article? Thanks as always!

Guy, I've never seen one before but I found this info on the 535.
P goes to the Pilot lamp. Not sure but if that gets grounded it may damage the flasher.

This 6 volt flasher came on many of the 1950’s cars. It is also considered to be the most universal 6 volt flasher in that it has 3 terminals when needed and is a heavy duty flasher.
These instructions are always on the box flashers come in
X — Power (hot lead)
L — Load (to switch operating lamps to be flashed)
P — to Pilot indicator lamp (this connection may be omitted. Flasher will operate properly either way)

Guy, After more research, I'm now thinking grounding the P wire going to the indicator lamps may work, as thats how the lamps get their ground.
But you may have to remove that flasher P terminal from the socket so it won't damage the flasher.

Do the pilot lamps flash in sequence with the external lights, or opposite? Ie when externals are ON, the pilots are OFF, and vice a versa? Looking at the schematic I think the pilots are opposite to the externals.
If opposite, bad or resistive grounds at the external bulbs and sockets would affect the pilot bulb operation. (When the flasher is OPEN, the P terminal is powered, and the pilot bulbs ground through the front turn filaments.)
If 'opposite' operation isn't important for Ops or PV, remove the wires from the P terminal and ground them directly. The pilots will be in synchrony with the external lamps. Leave the P terminal on the flasher vacant.Comment
