Thank you for providing the scan of the 1933 wiring diagram and the Mazda bulb numbers for the headlights.

I hope you can find the scan of the bulb chart with full bulb particulars as that would be interesting to see too.

Does anyone know where I can find the types of light bulbs that are used on my 1934 Packard 1100?

Is this information in one of the shop manuals?

Or is the best way to accomplish this is by pulling each lamp on the car and look for a label?


I have the following lights on my car:

2x headlights
2x pilot rays (non-Packard accessory)
2x fender lights
2x tail lights

1x interior dome light
1x interior dash/map light
(unknown quantity of) instrument lights

While driving a 1946 Packard Clipper Limousine I noticed that the needle in the gas gauge moved around alot - a considerable, distracting flutter. Is this correct behavior for this car?

The wiring diagram shows a simple circuit. According to a recent post in this forum, the Tank Unit (sender) is a resistive model in which it changes resistance depending on level of fuel.

Is it normal for the float in the tank to move around a lot and cause the needle in the gas gauge dash unit to move a lot as a result?

It's been a couple of weeks since my last update on this drivability issue with my 1934 1100 and I am pleased to say that we found the cause.

Took a break from work so I could drive the '34 over to the shop. We removed the distributor and placed in into a Sun distributor tester and discovered the following:

1. Mechanical advance was correct and working properly
2. The dwell was not correct - so we corrected it
3. Spark plug wires were working properly
4. Replaced two of the spark plugs as the screw tops were stripped.

The car now drives well throughout the RPM range, no more loss of power, no more bucking or stumble. How interesting that the dwell makes such a big difference.

Thanks for the helpful responses. I will update this thread with my progress and the solution, once found.

Drove my 1934 Packard 1100 Standard Eight with a stock (but rebuilt) carburator on the highway today. As I approached 50MPH I could feel the car start to hesitate as if it was losing power. As I pressed the accelerator to increase speed past 50MPH the car started bucking and backfired.

As soon as I slowed down below 50MPH the car behaved normally again. I left the highway and for the next 20 minutes the car continued to drive strongly under 45MPH which is its normal behavior. It idles well with an infrequent light paff but again that's been normal for all the time I've owned the car. The car starts easily, even after sitting in the garage for a couple of weeks, idles smoothly and warms up without issue.

After this behavior on the highway I experimented with the throttle around town. I noticed that in any gear as I increase the throttle past 2/3rds throttle, and the engine RPMs increase towards the higher end of the RPM range, the power drops, the engine power seems to hesitate, and it doesn't seem to breath correctly as if its being held back. I am very gentle with this car and cannot be accused of racing the engine in any gear. I should be able to drive the car faster than 50MPH on the highway with its stock 3-speed transmission and non-highway gears, correct? I know it should not be bucking.

Anyone have ideas for diagnosing the source of this hesitation and the associated lack of power at 2/3rds throttle?

Looking at photos of the final 1935/37 version of Macauley's Packard Custom Speedster I noticed the resemblance between the fenders on the Packard in your photo and the fenders on this last incarnation of the Speedster. Doesn't mean they are the same car, but food for thought.

I should read my own library of Packard books more closely. First I checked the mascot book and came up empty.

However, the book titled "The Magnificent Packard Twelve of nineteen thirty four" has a clue. In the chapter devoted to the "Packard Custom Speedster" there are photos of each iteration of the car. The caption for the photo of Edward McCauley (sic) standing next to the car states that "E. M.'s special running dog radiator mascot is in place".

That's a good enough answer for me.

I've attached a couple of images of the book, including a photo of the final incarnation of the car. Note that with the creation of the 1935/1937 car the radiator mascot is now the LeBaron "ring of fire" style of hood ornament.

Thanks for the links to the original scans of the 1933 version of the Macauley Packard Speedster.

After blowing up the image I can tell that it is not a hood ornament from the Packard accessories catalogue. And it definitely is not the LeBaron style hood ornament. It looks like an animal with ears and a tail leaping out from the radiator cap. I am made even more curious by these photos.

I wonder what it could be?

Does anyone have an idea what hood ornament appears in the photo of the 1933 Packard Macauley speedster as seen in the "Making of Modern Michigan" archives?

When I look at the photographs of the car the hood ornament appears to be attached to the radiator cap, has a low profile, and stretches out over the front of the radiator grille. It was suggested to me that this was the LeBaron hood ornament but the "ring of fire" ornament is much shorter in length than this one appears to be. To my eyes it looks like a rabbit leaping from the radiator cap, but the images aren't clear enough to be sure.

Perhaps this is a one-off ornament used only on this Packard? Does anyone have a better photograph of this car and the hood ornament?

Inscribed on photo back: Packard MaCauley speedster, note alterations on 1933 version: full front fenders; high peaked crowns, full deading, skirts, pontoon rear fenders; high peaked crowns, beading around wheel openings, "Packard Twelve" hub caps, twin tail lights with vee lenses; tops of rims repeat Packard radiator shape theme, shortened rear bumper to fit within pontoon ends; slightly veed, plain dash replaces engine turned dash of 1932 version, 1934 type instrument panel; radio heat at top center, brake sector.

P.S. I don't know if this has been discussed previously on this forum (I searched but didn't find a discussion) so I apologize if this has been discussed at length.
