hi all - i have posted a bit on the cosmetics clean up of a 'rougher' sure shot i picked up on a bit of an 'impulse buy' the other day that i am regretting a bit .. but trying to make the best of it i figured it is time to learn how to really get into understanding my ems top to bottom and the proper process for getting one running properly when it won't start!
this is i am sure is a good idea so i don't burn my place down .. just ask jason
at any rate - i have no idea where to begin on a 'project' run through and someone far wiser than i said i should just give the machine and every switch and relay the once over, systematically rather than trying to chase problems which could likely create new ones ...
so, i have the manual and i have the schematic ... where do i start ? what do i do first ?
here is the low down on where machine is at ...
i removed two mods - a button wired to 15amp and kick out hole ..? and one wired to coin door too
i resoldered those older wires / connections
power on
backbox lights up
press start button
playfield lights up but ball does not fire into shooter lane
finger flip ball into shooter lane, a chime sounds??!? and flippers are activated
no ball in play light lights up
on playfield most items register a score ... the lower slings actually award 10 points and 100 at same time! and chimes don't typ sound on any
i suspect the good old ax relay is all gummed up, and the sequence bank that tracks the rollovers and pool ball 'rack' somehow isn't fully awake either
lots going on and lots to sort ... but where to start on a systematic approach??
calling em gurus - come to my aid
can take pictures as needed too
cheers, Ron
