I've had an issue with my Flash Gordon that I attributed to a power surge, but it was probably just a coincidence.
I've now determined that something located on the playfield makes the F5 fuse blow (cause it's fine when I remove the J1 plug), which controls the GI and apparently part of the sound (sometimes just the speech will stop, sometimes all the sounds).
I just can't seem to find the source of the issue, as I can't see anything that could cause a short-circuit on any of the lamp sockets. Sometimes it'll work again for a couple hours of play after I twiddle a bit here and there under the playfield, but the fuse will blows again at some point while playing.
I know I'll have to be a bit more systematic to locate the cause of the issue (I would appreciate some advices to get there the most efficiently possible), but I might go through a lot of fuses.
To get to the point, F5 is a 20 amp fast-blow fuse, and I've had no luck getting a 16 amp circuit breaker to work in its place. I'm afraid to use a 20 amp breaker because I believe it'll be too slow compared to a fast-blow fuse and it might damage the circuit.
As far as I can tell, there's no circuit breaker with a value between 16 and 20 amps. Would it even be advisable to use one ? Am I condemned to just use lots of fuses ?
