Brass top coils

Post by Danny Carstensen » Fri Mar 03, 2023 12:23 pm

Are the capacitors the same in all coils, and the points look to be either style?

Ron or Brent would be the go to for a more detailed answer however it is my understanding late 1913-forward that’s correct but I stand to be corrected.

Danny be aware that the way that the wires attached on the inside are slightly different on brass top coils than the regular coils.
With the exception of the bolt with the spring tensor, the wires that go to the points and bridge on the brass top actually go through the top wood plate and are soldered to a rectangular piece of metal that has slots for the small metal carriage bolts to lock into. Those bolts may feel loose if you disassemble the points. Some folks solder them into the plate where the wire connects. I have not but I do make sure they are in the slots before tightening the new points down. Others may have a better technique. Best John
