I had to replace the ignition switch on 1958 Ferguson TO 35 with the Standard 23 C diesel.
The old switch was wired so that the resistor and glow plugs were NOT hooked up. Don't know why, I checked everything over on them and cleaned all contact points of wiring nothing seemed amiss.
Old ignition switch would engage starter if you turned it to right or left. I don't think this is correct.
Installed new switch which is sourced from here and is indicated the one with "heat" position for a 23 C.
I have again cold start with turn to right, and resistor/glow plug if I turn to left, but this also immediately engages the starter.
I thought the heat position was just that and you held it for 30 seconds, then turned key to start.
Have I connected the wiring wrong?
New ignition switch looks like the old one with 3 larger prongs on back, (marked 1, 2 3,) one of which has a smaller prong attached pointing toward the center of switch making a total of 4 connection points.
Any thoughts or pix of what the correct path is.
