18" cable from the Positive post to the head stud nearest the thermostat housing. 

18" cable from the negative post to the starter solenoid terminal, then 18" from he solenoid to the terminal on the starter. 

All cables heavy gauge.

The above are not incorrect, but there were a couple alternatives for the ground engine end. Some generator bracket mount studs are long enough to accept the end of the ground cable.  Alt. 2,  you may have two or three head bolts that have a larger head (11/16ths comes to mind) that have the head drilled and tapped for a bolt. The cable can go there.  The other option is a braided ground strap to any of the three mounting locations.  You may also mount a cable or strap from the fire wall to the engine via a bell housing bolt or another threaded head bolt.  Clean secure grounds are vital to 6 volt system's proper function. Its amazing how much brighter headlamps can be when they have clean secure connections and a proper ground.

My most informed opinion is that the factory location is one of the bolts or studs that holds the generator bracket to the block.  Most likely reason that alternate locations are used is that it is a pain in the a$$ to fasten it there with the generator, fender, and battery shelf in place!  Good luck.

MACS,

    Greg and Niel are exactly right! I have '46 D-24 engine compartment factory photos. The ground cable goes to the front bolt holding the generator bracket to the engine block.

The bolt is double ended, meaning it has a hex in the middle and threads on both sides of the hex. One thread is longer to go into the block through the bracket. Once tightened, the ground cable, or strap in my case, goes on the exposed threads on the outer end of the bolt. PITA !!

Niel,

    Again, you're right on target.

   Chrysler calls that front-most fastener a "Generator Bracket and Ground Terminal Screw". Part number 866 890 is described as '3/8-24 (5/8) 7/16-14 (1 in.) x 1 31/32 long'.

    For your info, the rear fastener is 122 253, named a "Bolt" and described  as '7/16-14 x 1 in.'.
