'36 P1 ,P2 fuel gauge question and turn signal question

[Lew]

Re; the gauge, I found info. in a ' Motors Manual' that  the '36 used an AC Neco gauge which is non adjustable. I think one can disconnect the tank lead wire and see if the gauge reads full with ignition on, thereby suggesting the tank sender is faulty.
The front turn signal bulbs are 6v. sealed beams in fog lamps. I replaced the battery with an optima and the bulbs light as connected to the battery via the ign. switch. Perhaps we should add front independent turn signal lamps as suggested with lower cp bulbs.
Many thanks for the info.

Lew,
With respect to the fuel gauge, if you take the gauge assembly out of the tank and move the arm from all the way down
(arm at rest) to all the way up, the dash gauge should move from "E" to "F".  If you can't get it to read "E" when the arm
is all the way down and or "F" when the arm is all the way up, then there is most likely some problem with the resistance
in the tank gauge.  But, the problem could also be with the dash gauge.  Tod Fitch has a good gauge test write-up on his
website about fuel gauges.  You might want to take a look at that.  Google the phrase Plymouth the First Decade.

Looking at my copy of the factory service manual, it seems the '36 uses the two wire thermostatic type fuel gauge. Sorry, but I don't have a write up about that.

Re:  using fog lamps as turn signals.  I would think that the bulbs in the fog lamps are not designed to act as turn signals &
draw too many amps to be used that way.  You need a smaller bulb for that purpose, like the size of your taillight bulbs.
Your turn signal assembly should have enough wires coming out of it so that one wire goes to each of the four turn signal
bulbs.  I added turn signals to my car and I can send you the wiring diagram for it.  It should be the same as what would be
used to wire your car.  I don't remember if your car has dual filament bulbs for the taillights or not.  If not, they will have to
be changed to dual filament sockets and bulbs.  I know your front parking lights are not dual filament.  The front parking
lights on my car were not dual filament, so I had to change them to dual filament when I added turn signals to my car.

Good luck and take care.

A number of the early fog lamps used 21 candlepower bulbs and that is the same as the typical stop light for a lot of years. So, given a conservative/run of the mill fog light bulb (as opposed to a high power one) might be a good match for the application. For what it is worth, I know a number of people who use fog lamps for their front turn signals and it seems to work reasonably well.

Does any one know how to calibrate (if that's even possible) the 6 volt elec. fuel gauge ? I understand that sometimes the gauge needs to "heat up" to register properly. A ground wire has been added at the tank sender to make that a more solid connection. The sender appears to be functional , along with a new float, because the gauge needle moves.  Is bending the the sender float the only way to make adjustments?
2nd question: Have 6 v.front  fog lamps used as turn signals and the lamps appear to be connected directly to the battery  via the flasher. We're in the process of trying to trace down the signal wiring which isn't original color coding. The battery sometimes can't keep the turn signal circuit lit. Where can we hook up the circuit to the alternator? Would the power side from the flasher connect to the back generator terminal of the ammeter ? One of the 2 terminals appears to connect to the horn and starter, the other to the generator (alternator).
Thanks for any input.
