Looking at the manual, should be a red wire & a brown/violet wire. Red goes to the banded side of the diode, brn/vio goes to capacitor. But first check the coil and diode. Coil must not read less than 1 ohm. If bell starts ringing when machine is turned on, then there are problems on the driver board. Q43 is the driver, Q42 is pre-driver, IC4 is the trigger for the bell.
