Thank you so much. John

I need help with a few more dash bulbs for my '48. I need the Bulb numbers:

1 - Instrument Switch Panel Bulb
2 - High Beam Indicator Bulb
3 - Flasher Bulb
4 - Ignition Switch Bulb
5 - And lastly, there are three bulbs at the center of the dash; High Beam Indicator, Flasher, and I don't know what the 3rd one is for. I need that bulb as well.

Thank you!

I want to add a push button start switch to my '48. I am trying to determine which wire I am supposed to route to this button. Would it be the wire from GA on my Ignition Switch that ultimately goes to the starter?

Thanks in advance.

John

Thanks a lot guys. A lot of help.

Hello All,

I have converted my '48 Packard from 6V to 12V. Some time back I came across a table showing all of the bulbs that needed to be replaced, but I can not find it now that I need it.

Can any of you help me out with this? Thanks a bunch.

John

One more question. Wire # 66 on my diagram.

For 6V, it was connected to AMM (+). With 12V should it still got to + since it is going into the splice that feeds into the light switch, the fuse block and the ignition switch? Or do I connect it to (-) as shown?

Attached is my updated 12V Small Block Wiring Diagram.

The changes are as follows:

1) I added a Start Button
2) Took the Alternator Terminal 1 wire out of the splice and directly wired it to a warning light.

So, I took liberty with the push button and wired it directly to the starter.

So this opens 2 more questions for me.

Regarding the Warning Light, if the owner does not want a warning light, what should I do with this wire? If he is OK with a warning light, where do I get one and how do you wire it up? Straight to ground? And what about this resistor I keep hearing about? Where does that go?

Second question deals with push button start. In the '48, when the gas pedal was depressed, the wiring circuit took voltage from the Ignition Switch (GA) thru the Ultramatic Transmission, then thru the Carburetor, then to the Starter. This is why I went straight from the Ignition Switch (GA) to the Starter. Is this correct?

Ahhh yes, the push button. I need to get that into my diagram.

The alternator is a stock 1970s style that puts out I believe about 50A?

I understand your point about not wiring the #1 Alternator terminal to the splice. I read your link and it says to use this wire for a warning light or resistor. The '48 does not have a warning light, and I have no idea what/where a resister is for.

Thanks again Howard. Funny thing is, the Temp Sender is the same between the two engines! I took the one out of the '48 Packard and it fit the Chevy perfectly. And there is good coolant flow around the sensor.

The Oil I have not figured out yet.

As for everything else that need to remain 6V, I am installing a step-down transformer for those.

OK, I need some validation.

Working on a car where the owner wants to convert from 6V to 12V. But it is a bigger issue than that. He dropped a Chevy 350 into the car.

I created 2 wire diagrams. The first one (entitled 48 Packard 6V)shows every wire that has anything to do with the '48 Packard engine.

The second one (entitled 48 Packard 12V Chevy 350)shows the '48 with the Chevy 350 wiring. I need to know if I show all of the wires correctly on the second one.

Please take a good look and either let me know if I have it right, or what (if anything) I missed or need to change.

So far I have been told to swap the wiring to the AMM Gauge + & -, which I did. My biggest concern are the wires from the Alternator & Distributor. Do I have these correct? Do I have everything else correct.

What a pain this has been, but learning a lot which is a good thing.

Thank you so much!
