So I don’t own one, but I repair it for the local arcade. Any suggestions on how to rebuild the hand or any good guides for it? Can it be done in one shot? The game can’t really be down for long so if it’s extremely involved I probably can’t do it.
Also the hand works in test mode, I can move it just fine, but in game it blows a bunch of fuses.

Also this game suffers from the constant rebooting issue if you have too much going on, and the operator insists it’s not the power supply even though it obviously is. Is it cheaper to put the little board in it instead of rebuilding it or whatever needs to happen to fix it properly?

Quoted from cynric:

There is a fairly big capacitor on the cpu board (100µF I believe), try replacing that against the reboots. For the fuses there is a service bulletin from WMS to power the hand magnet from another fuse: https://www.ipdb.org/files/3683/Williams_1995_Johnny_Mnemonic_Service_Bulletin_87.pdf

Considering the batteries I just replaced had a GOOD TILL date of 1997 I assume he probably bought it, opened it and plopped it down and never ever did this. I will check to see if this fix has been implemented.

Thanks so much for the help!

Quoted from dudah:

Take it apart, clean everything, relube the screw rods with SuperLube, clean out the old grease of of the gearbox and relube with SuperLube, replace the X and Y nuts, reassemble in reverse order.
Take lots of pictures before you take it apart.
Should be able to knock it out in under 90 minutes.
When retesting the first time, make sure none of the wires get snagged.

Thank you, I will do this aswell!
