Hi,
I am having an interesting think happen with my Mata Hari. This just started happening. The 4k bonus lamp starts off unlit. Once it is lit it remains lit until the next ball. It seems to happen when the 2x bonus (and 3x and 5 x) has been achieved and then it stays lit. When no bonus multiplier is lit the lamp behaves normally.
I swapped out the SCR that controls that lamp before I noticed the pattern with the multiplier and it still happens so I am not sure where to look next. Any ideas? Connector issue?
