Hi All! Has anybody else had problems with the opto board for the jeep? My second one has just failed and I am having trouble finding one. The part number is 520-8102-00. This opto board is directly underneath the playfield jeep and senses when the jeep swings left or right. Has anybody fixed this opto board perhaps. Stern has them on backorder and I can't find a distributor that has one in stock.

Any help would be greatly appreciated!!

Had the same issue, just resolder the contacts and is good already, but yes... is a issue for sure.

RGAires, when you say resolder the contacts could you indicate which one on the card ? The four by each opto ? In total the eight ?
If you can indicate me on the picture I made, the correct contact to resolder I appreciate your help. Regards.
