I've just picked up a Mata Hari with Alltek MPU and SDB.
Top LET Bumper and 1 Chime have cooked coils with all wiring in place (power not cut off).
Wiring to both coils is still in place and the associated LED fires in test mode.
The game continues to play despite the burnt coils getting triggered.
Does this sound right - typical behaviour?
Is the coil protection kicking in?
Not sure if I should be seeing errors on the Alltek SDB - the game continues to play complete games???
Safe to assume I can simply replace the Coils?
