pfaff 474 post bed

[Hurbie]

hello all , 

 

a question about a "new" to me , Pfaff 474 post bed sewing machine , the machine looks like it is altered by the previous owner (the top roller system doesn't seem original to me). it's fitted with a Efka euramot AB62CV1466 , al seems to work as it should do , except i can't find a reserve lever/button .

so am i right in thinking the reverse is controlled by the Efka motor control ? if so , how does that work (if you reverse the motor the bobin would turn the wrong way round )

i don't see anything electrical that would reverse the bobin , only solenoid is for a (now defunctional) thread cutter .

next to the column is a little switch board with 2 buttons (red and yellow) and a small toggle switch above it , nothing seems to work from that control box , so i need to see if there's a wire damaged .
