Machine is a Zaccaria Pinball champ 82
On connector Cn1 of power driver, I do not get the 6.5 Vac on the 9/10 and 11/12 pairs. Continuity with the power transformer is ok, only I cannot measure on th transfo as pairs come i to a plastic plug as show on the pic. Other voltages are ok. Does it mean the transfo is out of order, or is any action possible ?
