Excellent info.. Thanks for the time to label everything JohnieG.. I do appreciate it. To get to the transformers, I need to pull that other cover off the back of the changer. There are a bunch of screws holding the cover on.. I didn't know if they were holding anything else or just the cover. Guess I'll find out soon enough.

Is the failed zener a common problem on these changers ? Mine had scorch marks just like bubba's, again with no other physical damage evident..
Do the CREMs run off AC line voltage or regulated 12V ? What about the payout motor (inventory switch) ? (I'm guessing CREM is AC and payout is DC?)

Depends on the make & model of your coinmech, check your electrical schematic on the machine, typically, most CREMS are line voltage, BUT, that depends on the machine, ie;a 24volt coinmech will fry it's CREMS on a 115 volt machine application, the payout motors can be either AC/line, AC/low voltage, or DC/low-voltage, again it depends on, some of the very early motors were AC/line voltage, this is why I'm cautious & don't like to generalize, besides, "ifin ya' kill 'em, he won't learn nothin' (the riddler/batman) 
As for the the Zener, it's as I descibed it, it's part of a chain of failure events, if you exceed the circuts design, it will lead to component failures, most often, it is the victim. not the cause, but once damaged, it'll damage a lot of components & you end up with a "ghost" in the machines coinmech.
Once you replace any component, you have to benchtest & "burn-in" the 'mech before you put it back into the machine, the coinmech can , and will damage the door-wiring harness, not only is it a pain in the butt, (damage someones V-81 RC Cola & see what happens!) but it's a fire hazard too, sometimes it doesn't pay to "patch" |

I should've mentioned that I'm using an S75-9800A mech.. I think it was you that helped me through replacing the zener.. and I know what you mean about damage.. mine came 'welded' to the wiring harness.. (well pin1 was welded anyway).. I do have a new mech, I just figured it would good to have the old one as a spare..

Well, the more I'm hearing, the more it sounds like I'm not gonna play with it. I've got a working board changer now, and I don't need to fix this one, just wanted to play. I'm gonna shelve the changer, and prolly toss the board.. It's not worth causing more damage to my now working machine to save a few bux. I learned alot from this discussion though... thanks!
