I need some help getting this question answered:

I finished working on a Skylab to deliver to a friend. This is the first game I have fixed to sell to someone else. After setup, the game worked for about 10 minutes when it shut down completely. Checking the fuses, the 15 Amp fuse on the 24V line had blown (red arrow on schematic). Losing 24V took out the Lock Relay which controls the two 6V lines (highlighted in yellow). When I pulled the fuse on the 24V, 15A spot, it was the fuse in the picture below. It's a 5A fuse!

Here is my question, how can a 5A fuse handle being on a 15A circuit? I ran this machine through a lot of games after I finished fixing it before delivering. I had no issues - please help me understand what could have happened.

I felt awful - way to deliver a giant paperweight.

Installed the correct 15A fuse and the game started right up. Thank you for the help
