It shows a flasher all right but is not showing it correctly. If you look at it, both indicator lights R&L are connected to the same terminal.

The factory diagram is correct. Say you want to flash the L signals. When the lever is moved and the flasher starts the L side flashing, both indicator lights get power from P on the flasher at the same time. Notice the wire from the other side of the L indicator bulb. If the bulbs were connected so the left and the right indicator bulbs were connected to their respective sides then you would have the same power to both sides of the indicator bulbs at the same time and no light. With the other wire from the L indicator bulb connected to the R side lights, when the flasher puts power to the indicator bulbs it goes thru that filament and over to the right side which is just sitting there not connected to anything but ground thru the filaments of the outside bulbs. The L indicator bulb gets a ground by going thru the filaments of the R side outside bulbs and will light while the R side bulb sees the same 6v from the flasher P terminal on one side but also 6v coming from the flashing L side on the other wire so with no ground it cannot light.


Turn signal power is shown coming from battery side terminal on the back of the gas gauge. That is the terminal that was fed straight from the ign switch and Packard frequently used it to provide power to accessories because it was easier to get to than most ign switches. Connecting directly to the GA terminal of ign switch was done whenever it was easier.

Heaters were an accessory and Packard generally did not include many accessories on regular diagrams until 48 or so. Some earlier diagrams might have an extra single illustration of the dash showing a few common accessories. I found one diagram for the Clippers that showed the Deluxe heater, radio, fog, spot light and reverse light.
