Thanks in advance for any help. I am a total novice at repair.

I just picked up a Tri Zone that functioned fine for a week or so. Now all coils quit at once. I suspected a fuse, but looking at the schematics, the coils for the flippers are on a separate fuse from the rest of the coils. What are the odds that both fuses failed concurrently? I should be looking farther upstream, I guess, but where?

All switches and lamps are still functional.

When you pick up an old game, it usually has 85% incorrect fuses installed, so anything is possible.

You need to pull EVERY fuse and carefully read that it is the correct amperage (1A, 10A, 2.5A) and the correct speed (slo-blow, fast-blow).

A fuse can be a slightly smaller value (like a 2.5A in a 3A socket), but NEVER larger.

Hey there! Got a moment?
