Just brought a Joker Poker back from the dead. New CPU,Driver and power supply. Went through the entire pin and everything works as it should except for two things. 1st- with the starting a game or going to the next player the drop target bank with the aces and joker will not reset, it will score properly. 2nd- if you knock all 4 kings down with one ball, they reset during play. The one reset bank with the queens,jacks and ten works and resets as they should. So basically, the kings reset during play and the aces will not reset after draining the ball and moving onto the 2nd player. Thanks for the help.

Thans for any help that is given.

Did you check the fuse? If so did you check the pin in the connector?

Also, there is a transistor under the playfield. I cant remember which drop targets that drives..

I may have to go in the basement and check mine out.

The fuses are all goood (new) and tested. I repinned all the connectors but that doesn't mean it was a good crimp or something else.,I'll check it.I have the king issues solved, because hitting them all first scores 500 then it resets and they are worth 5000. Am new to this so please have just a little patience. I do need help with the issue of the aces and joker never resetting. If they are put up manually , they do score properly. Everything else works as it should, so am real close to having a100% working pin. thanks again for all the help.

So do the aces and jokers ever re-set, or only if you do manually?

They only reset when turning the pin on and after that it blows the fuse. i just checked the connector and everything is tight as it should be to the driver board.

Is this the EM, or the ss version?

Oh, after re-reading the original post, I see this is the ss version, missed that the first time through. Check the transistor for that coil.

Thanks for all the help. Inslalled an old driver board and everything works perfect. Will be sending back the Ni-Wumph driver for repair.
