Marty - I'd be checking the Fuse Holders on the Power supply. They are notorious from problems like the one you describe.

Check connectors - Which I think you have done.

Rebuild the 5V section.

That should cover it, I'd think.

Fuse holders done on Power Supply.  Connectors look OK...None appear burnt or discoloured and seem to fit OK (ie not loose)...

I think perhaps the 5v needs looking at...I've got all the bits except the 2N6059 and 330uf 35v cap.  I will order some from futurlec.com.au and see how I go.....




Go ahead with the rebuild.. This is a new issue with the game - isn't it ?

Just wondering if the reset is caused by any particular action on the playfield  - like hitting the same target etc.. I've seen a switch wired incorrectly which threw the switch matrix on a Bally/Williams and it caused a "slam tilt" once in a while..





Not really a new issue, has done it 3 times since I finished everything else (over 1 month period)....No particular action otherwise I would be looking at that matrix...Flippers have been used - that is the only commonality, but no targets the same etc...Unless a G.I wire is done incorrectly I cant suspect anything else...When it does go into tilt / slam tilt it comes up on the DMD as TILT, which has never done...Just finishes the game.....

Check and replace the metal fuse clips.  Replace them don't solder them up.

Yep, all fuse clips replaced with new ones on powerboard.  All others checked and seem OK.
