Quoted from dwightheinink:Hi guys,
I’n having some issues with the bulldozer, when I’m testing it in test mode he’s working fine with going up and down, but when multiball is lit he doesn’t goes up and down. I’ve allready checked the Eddy board and adjusted it.
Who could help me out?
Regards,
I agree its better to post in the RS club thread for more help.
Anyway. I had a similar problem where my dozer worked fine in dozer test but whenever I played the game it hung in mid-air and didnt move at all when it should. Eddy boards tuned in properly.
I tried pulling on the connector cables as suggested in the linked post above but didn't see anything register wrongly. Then I took off the dozer blade opto card (the card with the two opto sensors, close to the dozer motor) and when inspecting it with a magnifying glass I found several cold solder joints. I simply resoldered all points on the card (maybe 20 points at max) and added some fresh solder in the process. After that the dozer works perfectly.
