if i'm not mistaken zaccaria used a lot of williams parts so most of the hardware and underplayfield stuff should be interchangeable. switches, post, solenoids, coin door.......that sort of thing. for the stuff that's not standard fare you'll need to find a parts game or post wanted threads on the zaccaria list, mr. pinball,......zac em's do come up from time to time, so just be patient(doesn't have to be a combat unless you after game specific stuff, plastics, backglass...). you should be able to use or convert domestic parts to get the game functional tho.
the first thing to do is clean all your switches(don't adjust them just clean them, you can get into trouble adjusting switches too much). if you have a flexstone use it, then see where your at.
when you say it's stuck in reset mode. are the score reels just spinning? what exactly is it doing? on and em at start-up the score reels reset to zero. if the switches in that mechanism are dirty or missaligned the game will never know they are at zero and just spin, very common problem.
it's been a while since i've worked on one of these older games, so i will only be able to help you so much. clays guide is indespensible here. besides the sound board, your game should be like any other em. when i had my klondike, i just went through the guide step by step. after a day or so i was playing games.
