Hi All, Proud owner of a Gen 1 Locomotion with an amzing playfield. It was not working when i got it, so cleaned up some old battery corrosion and got it functioning fine, then a month or so later it just stopped working. Since then i have double checked my clean up work around the ROM chips, and all tracks seem to buzz out OK for continuity.
I found that the machine powers up, displays 0's on all the displays, however i cannot get into any diagnostics or coin up. So i assumed the switch matrix was stuffed, replaced both IC 40 and IC41, and now the machine will go into diagnostics....however is showing some strange behaviour. In the switch test, the switches work - partiularly i tested the coin switch and start button which are good. However, when i try to add a credit and start a game outside of the test, nothing seems to work.
The other strange thing, is that when i get to diagnostic test 4, all coils seem to fire together, and then the displays go blank.
Any suggestions on where to look or what to try?
