Quoted from L_satan:
Something strange with the Williams Flash I am restoring for a friend. It works fine, needs the basic board care, mechanical updates, but one very unusual thing; every coil has a fuse. I'd like to clean it up and get rid of them and the excess wires, but is it possible there is an issue upstream; if so,what might that be?
Curious to know if any one has seen this before.
It's possible that there *was* an issue where the main solenoid fuse was blowing at some point. And to address the issue, a previous owner probably fused each coil so that the game would still operate for the most part--probably while on location so it could still earn, even if one coil was out of commission.
It's entirely possible that the original issue was fixed when the owner found out which coil(s) was causing the main solenoid fuse to blow. When there's only one main fuse for all the coils, it can be an annoying trial-and-error process to try to track down which coil is actually causing the main fuse to blow.
Before you start taking out those extra fuses, make sure all the factory-installed fuses are correct according to the manual and see if you have a problem with it blowing. Also, make sure that the original wire on the harness is still long enough to reach the coil's lug.
