I recently acquired a Gottlieb Abra Ca Dabra. I've gotten most of the bugs worked out except one: On five-ball play, the pop bumpers are supposed to score 10 points when unlit and 1,000 points when lit. But on my game, the pop bumpers score 100 when unlit. (They do score 1,000 when lit.)
I know that on three-ball play the pops are supposed to score 100 points when unlit - and mine do. The only issue is the five-ball games, where they score 100 instead of 10 when not lit.
NOTE: There is no problem with 10-point scoring. The slingshots all score ten points when hit. Also, I cleaned the I-relay and that seems to be working fine, advancing the target light and alternating the lighting of the pop bumpers. It is only the scoring that is the issue. Any help would be greatly appreciated!
