In discussions regarding starter switches, there is mentioned of a "Ford Type" solenoid. Is that a particular solenoid that is preferred when using one in addition to the original floor switch? If so, how do they differ from other solenoids?

I believe the reference to a Ford solenoid was to the 3 pole configuration since a distributor lead was not necessary. 4 pole normally unused , but if necessary for a ballast resistor or distributor ignition coil (not really necessary)
There tractor styles look a bit period correct. Note if you read the instructions you carefully you'll see that you don't need to hookup the floor switch at all but can have it in place for appearance sake and hide the push button some where as a ant-theft device

'56 and earlier Fords are 6 volt, pick your favorite auto parts supplier. The '57 Ford went to 12 volt and added the second small lug which would normally not be used on a T.
No clue how long the tractors stuck with 6 volt.

Personally I have kept the stock Ford model T starting system, no issues, no problems. 100 year reliability is hard to beat.

Actually in 1956 Ford went to 12 volts negative ground.

The 49-50 Ford Pickup solenoid has a button on it for a manual override. In case something goes wrong with anything. Dan

Go to www.yesterdaystractors.com and look under Ford and you’ll find them. 6 and 12 volt.

You can bye modern style solenoids 6v or 12v with 3 or 4 poles at any automotive parts outlet. The "Ford" style refers to the 3 pole 6v not really a specific look, but mounting hole positions. https://www.google.com/search?q=6v+star ... V6BQgBENsB

Early Ford solenoids 30 and 40s were activated by grounding the small terminal . The push button in the dash had one wire and used dash mounting connection as ground. They look like the one that uses battery voltage at small terminal. Be sure you know which type you have.

I use a stock Ford solenoid on my flathead and T. Both are g rounding type.

John's is a good answer of what a Ford type is. Model A up until the 12 volt systems were positive ground.

The majority of the Solenoid's listed on an earlier post have to be ordered from the Auto parts outlets. They are available upon request but they don’t have them in stock.

I agree with Jeff above. Why change a proven system?

Here is some pro and con about changing to 12 volt in old tractors which might apply to any old 6 volt engines. https://antiquetractorblog.com/2008/12/ ... lt-system/

As far as Model T’s are concerned the original set up 6 volt worked for years and still works until you think you can improve upon it but why. To each his own in that dept.
