spark plates
#3

from antiqueradios:
(′spärk ′plāt)
(electricity) A metal plate insulated from the chassis of an auto radio by a thin sheet of mica, and connected to the battery lead to bypass noise signals picked up by battery wiring in the engine compartment. in other words, a cap to ground on the power line.

more than anything, i don't understand why it doesn't just short the 6 volts to ground with only a few ohms resistance. almost like the resistance increases [substantially] once the capacitor has charged up.

here's a picture https://www.antiqueradios.com/forums/vie...6&t=354480
