Transistorized ignitions

On pages 7, 9 and 13 of section 120 of the Master Parts catalog, it lists specific distributors for the '66 F100/F250 with 240, 300 and 352 with transistorized ignition. I have found nothing in the sales literature indicating that it was available in anything smaller than the F500. Also, if you look up the amplifier required for the transistorized ignition (12A027), it doesn't show it being available for anything smaller than an F600. Does anyone know if this was available as a dealer option?

Trying to put together a working transistorized ignition today would be a huge gamble as it requires specific wiring, coil, points, ballast resistor assembly, and amplifier (it could be done by using simple junction blocks in place of a tach block). The probability of an amplifier actually working is probably low too, but it could be restored by replacing the main component. I think it would be super cool to have a period correct ignition that lasted 4 times longer than standard points. Also, in '66 Ford simplified the design to eliminate the cold start relay.

Anyway, if anyone has first hand experience with one of these, I'd love to hear about it.

We used to work on an F750 dump truck back in the day that had one of the transistorized systems in it. They could have been ordered in an F100 on up, but how many people did? Back then most people thought of power windows and air conditioning as things that can go wrong. Transistors were a fairly new thing and people were uncertain about them. We've come a long way....

I had a '66 Merc 250 CS with the system. It caused me a lot of trouble because it used a ballast resistor instead of a resistance wire, and I couldn't solve the problem of the breaker points burning. I had not seen such an arrangement on a Ford and I couldn't find a wiring diagram (in those pre-internet days of old) so I simply replaced the whole system. I didn't notice if the distributor was different in some way. The amplifier was mounted on the right side kick panel. The engine tag had "T" stamped to the right of the other data.

I found it interesting that the MPAC lists standard points as replacements, but there were special low mass tungsten points made specifically for the transistorized ignitions and in the drawing you posted it depicts a lead with a bullet connector instead of a ring terminal or 90 degree boot. I certainly don't want to make my ignition even less reliable, but I was thinking of putting more modern guts inside the amplifier to still use the points as a signal to trigger a higher current to the coil. There was supposed to be a 7.5 +/- .4 ohm resistor in series with the distributor (wire 851 in your drawing) to reduce the current through the points significantly (like .65 amps IIRC). Maybe it was missing or it was bad/out of spec.

It's from the 1966 Light Truck Facts for Combination Salesmen. Covers the following models and series

Ranchero
Econoline
Bronco
F-100
F-100 4-Wheel Drive
F-250
F-250 4-Wheel Drive
F-350

I have the Ford and the Ford/Mercury editions. As I understand it these were one per dealership, unless you ordered additional ones (see below).

So your Mercury truck book shows all the options available on my 1966 Mercury Ranger??

LOL. The only option available on the Ranger was the Console.

Good one, though. Same book, just an insert page up front to clarify the measurements.

Your response was not what I expected. Sorry to burst your knowledge bubble but if I were to recall your previous testimony optional on the Ranger was bucket seats and optional console. Only the carpet was standard. Also, just to be a weiner my Ranger truck could have had the option of tu tone paint, styleside box and long wheelbase, cargo box, spare tire holder, 16 inch wheels and last but not least...automatic, overdrive, extra gauges and radio!

Those options are not specific to the Ranger and were optional on any truck so you can sure include them if you want. The bucket seats were certainly optional in later years and the Salemans facts book does show the seats as Optional in 1966 but I have not seen an example that could be verified yet. And it upsets ND when such things are said, so I try to keep that to a minimum unless he's not around.

Here in the 1970 Salesmans book they show both the Ranger and Ranger XLT with a bench seat.

And the bucket seats, while available, had apparently nothing to do with the Ranger package and couldn't be had with a Custom Cab and were only available in Parchment with black carpet and back cover.

One other thing to consider for 1966. While there were red and black upholstered bench seats in both Standard and Custom Cab - the only Parchment that I know of is in the bucket seat choice. Ditto for 1965 and Palomino upholstery choice.
