I believe this is a southeastern controlled , but it’s labeled as a kiekafier , does anyone have a similar schematic I could use to help fill in the missing information. ? This is the best I could fill in the old faded print
If it is labeled Kiekhaefer in the controller it’s a very good chance the controller was made by CJ Anderson out of Chicago and private labeled for Kiekhaefer. CJ Anderson is still in business and impressively still has copies of prints for almost all the controllers they built. I have gotten replacement prints for jobs made in the 20s-30s from them.
It is 100% an old Southeastern. I have (2) of them on my route. Unfortunately, no prints! I can tell you that 90% of the time the small shunt on the wafer relay brakes (as shown in the pictures you posted yellow wire). I have found that using "Super Flexible" wire from McMaster and soldering a new shunt will fix it better than a standard wire. Pull all the small shunts fix the broken ones then pull them again!!
