Ford-Lehman Wiring Harness

[CharlieJ]

Can anybody provide the wiring harness schematic for a Ford-Lehman engine?

Maybe this? (the red is my mod).

Courtesy of member jleonard who I think got it from American Diesel.

Hard to believe many will be still completely factory. It did get me going in the right direction though.

Thanks, that helps.

Interesting mod. Looks like a starter inhibit addition. One of my two motors has this mod. Prevents starter engagement if engine is already running. [emoji106]

No, just a power post for all the connections....

Also one more to the house bank through an on/off switch.

Ah OK. Here is my mod to keep an absent minded skipper, like me from grinding in the pinion gear. On the little Volvo diesels. I should add that this also assumes a diode based combiner is used, thereby the B+ term is at 0 V until alternator spins. This is how the circuit knows that the engine is rotating.
