Super C electrical

I got a new battery today and put it in the Super C and found that the starter turns the engine, there is spark at the points in the distributor and the lights all work. There is a wire with alligator clips on the ends with one end on the top terminal on the voltage regulator and the other end clamped to the air cleaner screw, would that have been done as a way to keep the generator charging all of the time or did it serve some other function? I forgot to get a picture of that. The lights are on in the photos but the camera flash dulled the a bit.

Zach, If the jumper wire is from the body of the VR it is to keep it grounded. If it is form a terminal on the VR it is to keep it charging. Eather bad ground or bad VR. oldiron29
 
The wire is probably a way to ground the field to make the gen charge more. You mite need to service the gen. Tons of gens are running around with the field terminal grounded and have been running that way for yrs. The owners manual even says to do that.I would check the regulator to see if its original or a replacement which had a seperate terminal for the lite circut.Check the Delco # on the gen to make sure you have a correct regulator. You say top terminal means you do have a later C as first ones used a cut-out on the top then later they went to a reg mounted below the genand then also ghanged lite sw to three positions instead of 4 because the hi-charge was no longer needed.
 
I'm pretty sure that's a Super C so it has a regulator.

Everything made after 1950 definitely has a regulator. 1948 might be the cutoff for cutoffs, though... not 100% sure.
