been looking for a OD for a 1950 long time, as luck $200 complete locally.
Ok its on the floor, I marked input shaft and tail shaft with paint. I figured out the cable lever - left is direct and to the right is od. My Ford shop book not really help for wiring thats Nasa. I figured the pass side what it is speedomter control 28 or so MPH. Now the solonid on the left, whats that do? I power it up with 6vts it sparks but don't do anything. Try do get that out no way. I think thats something to do with freewheeling? So, as I test on the bench, I am thinking I will use the cable and push the cable (gas pedal down) and release just like a truck (two speed axle) with out all those relays and gas pedal kick down switches. Question is what does the left solinoin do? does it lock out
free wheeling? Two wires on it, on one a dead spark & the other nothing.
The bench test; I find that i spin the marked input shaft, I have to put into neutral put lever on OD shift back to third I now am in OD...Read some have
a 3 way switch no good if my solinoid is bad solinoid $500 and 12Vts.
any ideas? sam
